Abstract

This invention belongs to the field of water supply sludge, specifically a method and apparatus for co-preparing river and lake treatment filler using water supply sludge. The apparatus includes four support pillars, with two fixed rings fixedly connected between each pillar. A PLC control device is fixedly connected between the two fixed rings. A reaction vessel is fixedly connected inside each fixed ring, and a vessel cover is fixedly connected to the top of the reaction vessel. A feed pipe is fixedly connected inside the vessel cover, and a discharge assembly is located outside the reaction vessel. This invention uses a motor to drive a transmission rod in reverse, which in turn drives a reciprocating screw to rotate.

This prevents blockage and ensures smoother material discharge. Furthermore, the movement of the baffle plate accelerates the material movement, thereby improving work efficiency.

Description

Technical Field

[0001] This invention belongs to the field of water supply sludge, specifically a method and apparatus for preparing river and lake treatment fillers using water supply sludge. Background Technology

[0002] Water supply sludge is a solid waste generated during water treatment. It is produced in large quantities and has a complex composition, typically containing organic matter, heavy metals, and flocculant residues such as iron and aluminum. Currently, the main methods for treating water supply sludge include landfill and incineration. However, these methods not only consume significant resources and energy but may also cause secondary pollution. In fact, water supply sludge has a large specific surface area and certain adsorption properties. If it can be rationally utilized to prepare river and lake treatment fillers, it can not only achieve resource recovery from waste and reduce filler costs but also reduce environmental pollution.

[0003] When preparing feedwater sludge, a reaction vessel is required to add different substances to the sludge, causing the elements inside the sludge to react. This facilitates subsequent treatment of the feedwater sludge, transforming it into a hardened packing material. However, during the preparation of feedwater sludge, because the sludge is in a fluid or semi-fluid state, after the reaction is completed inside the reaction vessel, it may cause blockage of the discharge pipe, preventing the sludge from being discharged smoothly and reducing work efficiency.

[0004] Therefore, the present invention provides a method and apparatus for preparing river and lake treatment fillers using water supply sludge in synergy. Summary of the Invention

[0013] Preferably, the spoiler strip is spiral-shaped, and the outer side of the spoiler strip is triangular.

[0014] The present invention discloses a method for preparing river and lake treatment filler material using sewage sludge in synergy, the specific construction steps of which are as follows: S1: First, the sludge is placed into the plate and frame filter press, then sludge conditioner is added to separate the sludge into solid and liquid components, and then the solid and liquid components are transported separately. S2: After the liquid is transferred to the first reactor, tartaric acid powder and sodium bicarbonate are added in a ratio of 1:(1.8-2). The total amount of the two additives in the first reactor and the solid-liquid ratio of water are controlled at 0.8%-1.0% to make the water system produce dense slow bubbles. After the bottom is clarified, the scum mixture is taken for later use. The scum and the solid phase of the water supply sludge are quickly mixed to form mixture ss1. S3: The mixture SS1 is then transferred to the second reactor, where xanthan gum and gellan gum solutions are added. The mass ratio of xanthan gum to gellan gum is 3:1-5:1. The mass ratio of the xanthan gum + gellan gum compound powder to water (feed sludge dewatering liquid) is 1:125~1:100. Sodium polyacrylate (PAAS) solution is then added, and the motor is started to drive the transmission rod to rotate forward, thereby driving the stirring plate, guide block, limiting plate and guide plate to rotate, so that the sodium polyacrylate (PAAS) fills the interior of the mixture. After the mixture enters the second reactor, the motor can be started again to completely mix the mixture and form a semi-gel mixture inside the second reactor. S4: The semi-gel mixture is then transferred to the third reactor. During this process, the motor is started, which drives the transmission rod to reverse, thereby driving the reciprocating screw to rotate, which in turn drives the baffle plate to move up and down continuously. This allows the baffle plate to continuously squeeze the semi-gel mixture entering the discharge cylinder, making the semi-gel mixture discharge more smoothly and quickly. S5: After the semi-gel mixture is transferred, water supply sludge dewatering liquid (without step S2) can be added to reduce the viscosity. This is because both the solid and liquid contain a large amount of calcium, aluminum and iron. As the calcium, aluminum and iron ions increase in the gelation system of S3, a highly absorbent superelastic gel with a certain mechanical strength is formed. S6: Subsequently, the superabsorbent polymer gel is placed inside the fourth reactor and kept at 55-60℃ for 0.5-1 hour, with gentle stirring throughout (30-50 rpm) to slightly break down the xanthan gum and gellan gum. Then, the mixture is rapidly heated to 200-210℃ and held for 15-30 minutes to break down the sodium polyacrylate (PAAS) and polyvalent metal ions (Al). 3+ / Fe 3+ The cross-linked structure breaks down instead of the PAAS completely decomposes, eventually forming a filler. Fillers manufactured in this state have a porosity of 45-60%.

[0015] The beneficial effects of this invention are as follows: 1. This invention uses a motor to drive a transmission rod to reverse, which in turn drives a reciprocating screw to rotate. This causes a blocking disc to rise and fall continuously inside the discharge cylinder, thereby squeezing the material entering the discharge cylinder and preventing it from adhering to the inside of the discharge cylinder. This prevents the material from clogging the discharge cylinder, making the material discharge smoother. Furthermore, the movement of the blocking disc can accelerate the movement speed of the material, thereby improving work efficiency.

[0016] 2. The present invention drives the stirring plate to rotate by rotating the transmission rod, thereby driving the limiting plate to move, and then causing the guide plate to rotate inside the stirring plate. This allows the material to move along the guide block to the guide plate, thereby stirring the material and making the material more uniformly mixed. In this process, the gel-like mixture is not greatly dispersed, thus preventing a large number of air bubbles inside the mixture from escaping.

[0017] 3. This invention uses the rotation of a reciprocating screw to drive the connecting frame to rotate, which in turn drives the striking block to move. Under the action of a spring, the striking block moves continuously inside and outside the discharge cylinder, allowing it to strike the material that forms an air film at the inlet of the discharge cylinder. This allows the material to smoothly enter the discharge cylinder and be discharged smoothly, thereby improving the efficiency of material discharge.

[0018] 4. Colloidal phase (5%): Xanthan gum / gellan gum can be controlled to dissociate into small molecule polysaccharides at 55-60℃, and sodium polyacrylate PAAS + metal ions can be controlled to break down into small molecule polymers + metal ions at 200-210℃. The two types of small molecules are carbonized in small amounts during subsequent heating to form micropores, which become the "pore-forming agent" of the filler, improving porosity and specific surface area. Sludge substrate (95%): Gradient heating allows the sludge-bound water to slowly vaporize, forming a uniform mesoporous / macroporous structure. Organic matter is initially carbonized at 200-210℃, forming a stable carbonized skeleton. Clay / quartz serves as inorganic aggregate, enhancing the mechanical strength of the filler and preventing pulverization. Metal ions (Al) 3+ / Fe 3+ ): It does not completely decompose with sodium polyacrylate (PAAS), but is uniformly dispersed in the packing skeleton, becoming a functional active site, which can improve the adsorption of the packing (such as adsorbing phosphorus and heavy metals in wastewater), allowing the packing to have the dual functions of "skeleton support" and "water purification".

[0019] 5. Utilizing the controllable dissociation and pore-forming properties of 5% colloid, it overcomes the porosity bottleneck of conventional sludge carbonization packings. With a porosity of 45%~60%, it significantly exceeds that of traditional sludge packings and features an open, multi-level pore structure (micropores + mesopores + macropores interconnected). This simultaneously meets the core requirements of large adsorption capacity, high mass transfer efficiency, and smooth water flow. Furthermore, Al… 3+ / Fe 3+ The uniform dispersion of the filler allows it to also adsorb phosphorus and heavy metals, achieving a dual advantage of "structure + function". However, if the colloidal phase is greater than 5%, it is highly unlikely that a qualified filler can be formed under these process conditions. The core problem lies in the conflict between temperature sequence and temperature threshold, as well as the irreversible thermal decomposition of polymer materials at extreme high temperatures, rather than a simple "breakdown / fracture". The final result is not a well-organized filler, but rather an amorphous residue after carbonization and degradation. Alternatively, the gel may block the pores, preventing it from functioning as a filler. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] Example 1: As Figures 1 to 10 As shown in the figure, an apparatus for preparing river and lake treatment filler using sludge co-prepared with water supply sludge according to an embodiment of the present invention includes several sets of support columns 1, each set of support columns 1 having four columns. Two fixing rings 2 are fixedly connected between the four support columns 1. A PLC control device 3 is fixedly connected between the two fixing rings 2. A reaction vessel 4 is fixedly connected inside the fixing rings 2. A vessel cover 5 is fixedly connected to the top of the reaction vessel 4. A feed pipe 6 is fixedly connected inside the vessel cover 5. A discharge assembly is provided outside the reaction vessel 4. The discharge assembly includes a mounting frame 7 fixedly connected to the top of the vessel cover 5. A feed pipe 6 is fixedly connected inside the mounting frame 7. Motor 8 is electrically connected to PLC control device 3. A transmission rod 9 is fixedly connected to the transmission end of motor 8. A one-way bearing 10 is rotatably connected to the bottom of transmission rod 9. A reciprocating screw 11 is rotatably connected to the bottom of one-way bearing 10. A discharge cylinder 12 is rotatably connected to the outside of reciprocating screw 11. The discharge cylinder 12 is fixedly connected to the inside of reactor 4. A limit strip 13 is fixedly connected inside the discharge cylinder 12. A blocking plate 14 is threadedly connected to the outside of reciprocating screw 11. The outside of the blocking plate 14 is slidably connected to the inside of the discharge cylinder 12. The inside of the blocking plate 14 is slidably connected to the outside of the limit strip 13.

[0025] During operation, the motor 8 drives the transmission rod 9 to reverse, which in turn drives the reciprocating screw 11 to rotate. This causes the blocking disc 14 to continuously rise and fall inside the discharge cylinder 12, thereby squeezing the material entering the discharge cylinder 12 and preventing the material from adhering to the inside of the discharge cylinder 12. This prevents the material from clogging the discharge cylinder 12, making the material discharge smoother. Furthermore, the movement of the blocking disc 14 can accelerate the movement speed of the material, thereby improving work efficiency.

[0026] Among them, a scraping assembly is provided on the outside of the transmission rod 9. The scraping assembly includes a transmission plate 19 fixedly connected to the outside of the transmission rod 9. Scrapers 20 are fixedly connected to both ends of the transmission plate 19. The outside of the scrapers 20 is slidably connected to the inside of the reactor 4. The transmission rod 9 passes through the transmission plate 19. The inside of the scrapers 20 is fixedly connected to the outside of the connecting frame 15.

[0027] During operation, the rotation of the transmission rod 9 drives the transmission plate 19 to rotate, which in turn drives the scraper 20 to rotate, thereby scraping the material inside the reactor 4, reducing the possibility of material adhering to the inside of the reactor 4, and accelerating the discharge of material, thus improving the efficiency of material discharge.

[0028] The transmission rod 9 is provided with a stirring assembly on its outer side. The stirring assembly includes four stirring plates 21 fixedly connected to the outer side of the transmission rod 9. Two guide blocks 22 are fixedly connected to the outer side of the stirring plates 21. Four limiting plates 23 are rotatably connected to the outer side of the stirring plates 21. The four limiting plates 23 are divided into two groups. A guide plate 24 is rotatably connected inside the stirring plates 21.

[0029] During operation, the rotation of the transmission rod 9 drives the stirring plate 21 to rotate, which in turn drives the limiting plate 23 to move, thereby causing the guide plate 24 to rotate inside the stirring plate 21. This allows the material to move along the guide block 22 onto the guide plate 24, thus agitating the material and making it more evenly mixed. In this process, the gel-like mixture is not significantly dispersed, preventing a large amount of air bubbles inside the mixture from escaping.

[0030] The reactor 4 is equipped with a transmission assembly, which includes a cover plate 25 fixedly connected to the inside of the reactor 4. The cover plate 25 is rotatably connected to the outside of the transmission rod 9. A rotating shaft 28 is rotatably connected to the bottom of the cover plate 25, and a planetary gear 29 is fixedly connected to the bottom of the rotating shaft 28.

[0031] The transmission assembly also includes a sun gear 30 meshing with the outer side of the planetary gear 29. The sun gear 30 is fixedly connected to the outer side of the transmission rod 9. A gear ring 27 meshes with the outer side of the planetary gear 29. A first mounting ring 26 is slidably connected to the outer side of the gear ring 27. The first mounting ring 26 is fixedly connected to the inside of the reactor 4.

[0032] During operation, the rotation of the transmission rod 9 drives the sun gear 30 to rotate, which in turn drives the planet gear 29 to rotate, which in turn drives the gear ring 27 to rotate.

[0033] The gear ring 27 is provided with a disturbance component on its outer side. The disturbance component includes a connecting plate 31 fixedly connected to the bottom of the gear ring 27. A stabilizing ring 33 is fixedly connected inside the connecting plate 31. A second mounting ring 34 is slidably connected to the outer side of the stabilizing ring 33. The outer side of the second mounting ring 34 is slidably connected to the inside of the connecting plate 31. The second mounting ring 34 is fixedly connected to the inside of the reactor 4. A turbulence strip 32 is fixedly connected to the inner side of the connecting plate 31.

[0034] During operation, the rotation of the gear ring 27 drives the connecting plate 31 to rotate, which in turn drives the baffle strip 32 to rotate, thereby agitating the material and making the internal material mix more evenly.

[0035] The spoiler strip 32 is spiral-shaped, and the outer side of the spoiler strip 32 is triangular.

[0036] During operation, by setting the baffle 32 to a spiral shape and the outer side to a triangle, it is difficult for materials to adhere to the baffle 32, thereby keeping the inside of the reactor 4 clean, reducing the time required for subsequent cleaning, and thus reducing the consumption of manpower and resources.

[0037] Example 2: Figures 4 to 5 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a striking component is provided on the outside of the reciprocating screw 11. The striking component includes a connecting frame 15 rotatably connected to the outside of the reciprocating screw 11. A slide rod 16 is fixedly connected inside the connecting frame 15. A striking block 17 is slidably connected to the outside of the slide rod 16. The outside of the striking block 17 is slidably connected to the inside of the connecting frame 15. A spring 18 is fixedly connected between the striking block 17 and the connecting frame 15.

[0038] During operation, the reciprocating screw 11 rotates, thereby driving the connecting frame 15 to rotate, which in turn drives the striking block 17 to move. Under the action of the spring 18, the striking block 17 continuously moves inside and outside the discharge cylinder 12, allowing it to strike the material that forms an air film at the inlet of the discharge cylinder 12. This allows the material to smoothly enter the discharge cylinder 12 and be discharged smoothly, thereby improving the efficiency of material discharge.

[0039] The present invention discloses a method for preparing river and lake treatment filler material using sewage sludge in synergy, the specific construction steps of which are as follows: S1: First, the sludge is placed into the plate and frame filter press, then sludge conditioner is added to separate the sludge into solid and liquid components, and then the solid and liquid components are transported separately. S2: After the liquid is transferred to the first reactor 4, tartaric acid powder and sodium bicarbonate are added in a ratio of 1:(1.8-2). The total amount of the two additives in the first reactor 4 is controlled to maintain a solid-liquid ratio of 0.8%-1.0% with the water, so that the water system produces dense slow bubbles. After the bottom is clarified, the scum mixture is taken for later use. The scum and the solid phase of the water supply sludge are quickly mixed to form mixture ss1. S3: The mixture SS1 is then transferred to the second reactor 4, where xanthan gum and gellan gum solutions are added. The mass ratio of xanthan gum to gellan gum is 3:1-5:1. The mass ratio of the xanthan gum + gellan gum compound powder to water (water sludge dewatering liquid) is 1:125~1:100. Sodium polyacrylate (PAAS) solution is then added. The motor 8 is started, which drives the transmission rod 9 to rotate forward, thereby driving the stirring plate 21, the guide block 22, the limiting plate 23 and the guide plate 24 to rotate, so that the sodium polyacrylate (PAAS) fills the mixture. After the mixture enters the second reactor 4, the motor 8 can be started again to completely mix the mixture and form a semi-gel mixture inside the second reactor 4. S4: The semi-gel mixture is then transferred to the third reactor 4. During this process, the motor 8 is started, which drives the transmission rod 9 to reverse, thereby driving the reciprocating screw 11 to rotate, which in turn drives the baffle plate 14 to move up and down continuously. This allows the baffle plate 14 to continuously squeeze the semi-gel mixture entering the discharge cylinder 12, so that the semi-gel mixture is discharged more smoothly and quickly. S5: After the semi-gel mixture is transferred, water supply sludge dewatering liquid (without step S2) can be added to reduce the viscosity. This is because both the solid and liquid contain a large amount of calcium, aluminum and iron. As the calcium, aluminum and iron ions increase in the gelation system of S3, a highly absorbent superelastic gel with a certain mechanical strength is formed. S6: Subsequently, the superabsorbent polymer gel is placed inside the fourth reactor 4 and kept at 55-60℃ for 0.5-1 hour, with gentle stirring throughout (30-50 rpm) to slightly break down the xanthan gum and gellan gum. Then, the mixture is rapidly heated to 200-210℃ and held for 15-30 minutes to break down the sodium polyacrylate (PAAS) and polyvalent metal ions (Al). 3+ / Fe 3+ The cross-linked structure breaks down instead of the PAAS completely decomposes, eventually forming a filler. Fillers manufactured in this state have a porosity of 45-60%.

[0040] The water supply sludge accounts for 95% of the mass of the filler.

[0041] During operation, the colloidal phase (5%) consists of: 1. Polysaccharide colloids: xanthan gum, gellan gum (natural polymer colloids that form a stable colloidal structure at room temperature); 2. Polymer electrolyte colloids: sodium polyacrylate (PAAS, also a typical water-soluble polymer colloid). These two types of substances together constitute the colloidal phase in the system, existing in colloidal form at room temperature / initial working state, playing a role in thickening, stabilizing, and film / structure formation. The colloidal phase not only contains monomers but also some components that assist in cross-linking and dissociation. Through synergistic effects, it constructs a colloidal structure at room temperature and achieves precise decomposition and pore formation within a specific temperature range; here, the colloidal phase = specifically used in the formulation for "burning / decomposition to create pores". The 5% colloidal component, together with the sludge substrate (dry sludge substrate for water supply), is responsible for both pore formation and providing the framework and strength: xanthan gum / gellan gum can be controllably dissociated into small molecule polysaccharides at 55-60℃, and sodium polyacrylate PAAS + metal ions can be controllably broken down into small molecule polymers + metal ions at 200-210℃. The two types of small molecules are carbonized in small amounts during subsequent heating to form micropores, becoming the "pore-forming agent" of the filler, improving porosity and specific surface area; Sludge substrate (95%): Gradient heating allows the sludge-bound water to slowly vaporize, forming a uniform mesoporous / macroporous structure. Organic matter is initially carbonized at 200-210℃, forming a stable carbonized skeleton. Clay / quartz serves as inorganic aggregate, enhancing the mechanical strength of the filler and preventing pulverization. Metal ions (Al) 3+ / Fe 3+ ): It does not completely decompose with sodium polyacrylate (PAAS), but is uniformly dispersed in the packing skeleton, becoming a functional active site, which can improve the adsorption of the packing (such as adsorbing phosphorus and heavy metals in wastewater), allowing the packing to have the dual functions of "skeleton support" and "water purification".

[0042] Based on the controllable dissociation and pore-forming effect of 5% colloid, it breaks through the porosity bottleneck of conventional sludge carbonization packings. With a porosity of 45%~60%, it is far higher than traditional sludge packings, and features an open, multi-level pore structure (micropores + mesopores + macropores interconnected). This simultaneously meets the core requirements of large adsorption capacity, high mass transfer efficiency, and smooth water flow. Furthermore, Al... 3+ / Fe 3+ The uniform dispersion of the filler also enables it to adsorb phosphorus and heavy metals, achieving a dual advantage of "structure + function".

[0043] If the colloidal phase is greater than 5%, it is highly unlikely that a qualified filler can be formed under these process conditions. The core problem lies in the conflict between the temperature sequence and temperature threshold, as well as the irreversible thermal decomposition of polymer materials at extreme high temperatures, rather than a simple "breakdown / fracture." The final result is not a well-structured filler, but rather amorphous residue after carbonization and degradation. Alternatively, the gel may block the pores, preventing it from functioning as a filler.

[0044] Working principle: The rotation of the transmission rod 9 drives the stirring plate 21 to rotate, which in turn drives the limiting plate 23 to move, and then the guide plate 24 rotates inside the stirring plate 21, so that the material can move along the guide block 22 to the guide plate 24, thereby stirring the material and making the material more uniformly mixed. In this process, the gel-like mixture will not be dispersed in large quantities. At the same time, the rotation of the transmission rod 9 can drive the sun gear 30 to rotate, which in turn drives the planet gear 29 to rotate, which in turn drives the gear ring 27 to rotate, which in turn drives the connecting plate 31 to rotate, which in turn drives the baffle strip 32 to rotate, thereby disturbing the material and making the internal material more evenly mixed.

[0045] After mixing is complete, the motor 8 can drive the transmission rod 9 to reverse, thereby driving the reciprocating screw 11 to rotate. This causes the blocking disc 14 to continuously rise and fall inside the discharge cylinder 12, thus squeezing the material entering the discharge cylinder 12 and preventing the material from adhering to the inside of the discharge cylinder 12. This prevents the material from clogging the discharge cylinder 12, making the material discharge smoother. Furthermore, the movement of the blocking disc 14 can accelerate the movement speed of the material, thereby improving work efficiency.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

9. A method for preparing river and lake treatment filler using water supply sludge in synergy, the method employing the preparation apparatus for preparing river and lake treatment filler using water supply sludge in synergy as described in claim 8, characterized in that: S1: First, the sludge is placed into the plate and frame filter press, then sludge conditioner is added to separate the sludge into solid and liquid components, and then the solid and liquid components are transported separately. S2: After the liquid is transferred to the first reactor (4), tartaric acid powder and sodium bicarbonate are added in a ratio of 1: (1.8-2). The total amount of the two additives in the first reactor (4) and the solid-liquid ratio of water are controlled at 0.8%-1.0% to make the water system produce dense slow bubbles. After the bottom is clarified, the scum mixture is taken for later use. The scum and the solid phase of the water supply sludge are quickly mixed to form a mixture ss1. S3: Then the mixture ss1 is transferred to the second reactor (4), and xanthan gum and gellan gum solution are added inside the second reactor (4). The mass ratio of xanthan gum to gellan gum is 3:1-5:

1. The mass ratio of the compound powder of "xanthan gum + gellan gum" to water (water supply sludge dewatering liquid) is 1:125~1:

100. Then, sodium polyacrylate (PAAS) solution is added, and the motor (8) is started to drive the transmission rod (9) to rotate forward, thereby driving the stirring plate (21), the guide block (22), the limiting plate (23) and the guide plate (24) to rotate, so that the sodium polyacrylate (PAAS) fills the mixture. When the mixture enters the second reactor (4), the motor (8) can be started again to make the mixture and the mixture completely mixed, thereby forming a semi-gel mixture inside the second reactor (4). S4: The semi-gel mixture is then transferred to the third reactor (4). During this process, the motor (8) is started, which drives the transmission rod (9) to reverse, thereby driving the reciprocating screw (11) to rotate, thereby driving the blocking plate (14) to move up and down continuously, so that the blocking plate (14) can continuously squeeze the semi-gel mixture entering the discharge cylinder (12), thereby making the semi-gel mixture discharge more smoothly and more quickly. S5: After the semi-gel mixture is transferred, water supply sludge dewatering liquid (without step S2) can be added to reduce the viscosity. This is because both the solid and liquid contain a large amount of calcium, aluminum and iron. As the calcium, aluminum and iron ions increase in the gelation system of S3, a highly absorbent superelastic gel with a certain mechanical strength is formed. S6: Then place the superabsorbent superelastic gel inside the fourth reactor (4) and place it at a temperature of 55-60℃ for 0.5-1 hour, stirring slightly throughout (30-50 r / min) to slightly break up the xanthan gum and gellan gum. Then quickly heat it to 200-210℃ and hold it for 15-30 minutes to break up the sodium polyacrylate (PAAS) and polyvalent metal ions (Al). 3+ / Fe 3+ The cross-linked structure breaks down instead of the PAAS completely decomposes, eventually forming a filler. Fillers manufactured in this state have a porosity of 45-60%.

10. A method for preparing river and lake treatment filler using sewage sludge in synergy, characterized in that: The mass ratio of water supply sludge in the packing material is 95%.
