Description

[0001] INTEGRATED TRICKLE-MBBR UNIT

[0002] Technical Field

[0003] The invention relates to an integrated Trickle-MBBR unit, which reduces, inside the body of a MBBR (Moving Bed Biofilm Reactor), the total amount of nitrogen (TAN, NH3N) leading to fatal consequences for the living beings in the systems of living beings and which further removes the undesirable gases (CO2, supersaturated N2, H2S, etc.) in the water by means of a two-stage degassing system inside a Trickle body that houses the MBBR body.

[0004] More particularly, the present invention relates to an integrated Trickle-MBBR unit, which reduces the footprint by realizing inside a single body the nitrification process having vital importance for the systems of living beings and the process of removal of the undesirable gases, reduces the area occupied by the unit, provides energy saving, requires no extra pump for pumping the water, and has a nested body structure.

[0005] State of the Art

[0006] The wastes, which are also referred to as the bioload (dead plant residues, dead fish, unconsumed food, excrement, etc.) and are present in the Closed or Semi-Closed Recirculating Aquaculture Systems (RAS) or Aquarium Life Support Systems (LSS), cause an increase in the total amount of nitrogen in the respective system. The presence of ammonium even in a trace amount leads to fatal consequences for the living beings inhabiting the aquarium. In order to eliminate this risk from the system, it is necessary to reduce the amount of ammonium, i.e., ammonia nitrogen (NH3N), to the lowest level possible.

[0007] The filtration systems are the systems used to clean the polluted water in any water habitat. The filtration systems consist of the equipment like the mechanical, chemical, biological, and disinfection units. With the integrated Trickle-MBBR unit based on the principle of combining the MBBR unit with the Trickle unit, the footprint of the Trickle-MBBR unit and the area occupied by the unit are reduced, the energy saving is provided, and no extra pump is required for pumping the water.

[0008] The patent document no. CN107428576A relates to a moving bed bioreactor and a water treatment method. The bioreactors and methods, which are particularly suitable for improving the water quality of the inland water bodies such as ponds or lakes harboring the shrimp, fish and other aquatic organisms under the conditions of aquaculture, are disclosed. The invention in this document discloses only a processing station, which is intended to receive multiple biofilm carrier elements, and a moving biofilm reactor, which includes an agitator to provide motion to the biofilm carrier element. However, there is no implementation where the filtration process is performed by means of the units of MBBR and Trickle being housed in an integrated body as in our invention.

[0009] The patent document no. WO2012087151 A1 relates to a carrier element, on which the microorganisms attach in the form of a biofilm, and said microorganisms are used to biologically treat water or wastewater. Said patent document discloses the combinations of the suspended growth processes and biofilm processes in the same reactor, i.e., IFAS (Integrated Fixed Film and Activated Sludge) processes. Although said patent document mentions the MBBR and the Trickling filter, it discloses a carrier element that rotates in order to distribute the mass. There is no similarity to the water treatment unit according to our invention where the filtration process is performed by positioning the Trickle unit and the MBBR unit in a nested body and where the water exiting the MBBR unit is transferred to the Trickle unit.

[0010] The patent document no. WO2014116196A1 relates generally to the water filtration systems and in particular to the water filtration systems used for filtering water from the aquaculture production systems. This patent document discloses a method for filtering the water from an aquaculture production system for return to the aquaculture to further support production. Although the document states that the trickling filters may be used for the water treatment processes according to the state of the art, it mentions only the water jet moving bed bioreactor (water jet MBBR). There is no similarity to the water treatment unit according to our invention where the filtration process is performed by positioning the Trickle unit and the MBBR unit in a nested body and where the water exiting the MBBR unit is transferred to the Trickle unit.

[0011] As can be seen, the state of the art does not have any patent document where an integrated Trickle-MBBR unit according to the present invention is used. As a result, the deficiency in the state of the art has made it necessary to develop an integrated Trickle-MBBR unit, which reduces the footprint by realizing inside a single body the nitrification process having vital importance for the systems of living beings and the process of removal of the undesirable gases, reduces the area occupied by the unit, provides energy saving, and requires no extra pump for pumping the water.

[0012] The problems resulting from the difficulties in terms of piping, cost, and operability presented by the Trickle and MBBR units, which cause the occupation of a certain space in the filtration systems, are significant. Moreover, the clogging particularly in the Trickle and MBBR units leads to high cost from the perspective of the process. The motion of the biomedia is provided by means of the U- shaped flow inlet pipe configured inside the MBBR unit. Thus, the cost for an extra blower is not required and the energy saving is provided. As for the Trickle unit, the clogging risk is minimized due to the absence of any covered area. Consequently, our invention is an innovative implementation, which produces solutions for the problems mentioned above and which is not available in the state of the art.

[0065] Detailed Description of the Invention

[0066] The invention relates to an integrated Trickle-MBBR unit (1 ), which reduces, inside the body (100) of a MBBR (Moving Bed Biofilm Reactor), the total amount of nitrogen (TAN, NH3N) leading to fatal consequences for the living beings in the systems of living beings and which further removes the undesirable gases (CO2, supersaturated N2, H2S, etc.) in the water by means of a two-stage degassing system inside a Trickle body (200) that houses the MBBR body (100).

[0067] The integrated Trickle-MBBR unit (1) according to the invention basically comprises at least one MBBR body (100), in which the biological filtration takes place for reducing the total amount of nitrogen, and at least one Trickle body (200), which houses said MBBR body (100) and has a wider body and in which the undesirable gases are separated from the water that has been subjected to the filtration in the MBBR body (100). Figure 3 and Figure 4 show the MBBR body (100) inside the Trickle body (200), by making said Trickle body (200) transparent.

[0068] The integrated Trickle-MBBR unit (1) according to the invention comprises at least one water pipe (105), one end of which enables the water to be subjected to the biological filtration to enter and the other end of which enables said water to be delivered into the MBBR body (100). One end of said water pipe (105) serves as at least one water inlet (105.2), via which the water enters, and another end of said water pipe (105) serves as a water outlet (105.1 ).

[0069] The integrated Trickle-MBBR unit (1) according to the invention comprises at least one reservoir (130), which is configured in the lower part of the MBBR body (100), has holes on the sides thereof and slits on the top thereof to permit the entry of the water, and enables the water processed in the MBBR body (100) to accumulate; at least one pipe (140) with one end starting inside said reservoir (130) and another end protruding via the upper part of the MBBR body (100), said pipe (140) allowing the discharge of the water inside the reservoir (130) to the outside of the MBBR body (100); and at least one guide (205), which is positioned opposite the protruding end of said pipe (140) and guides the water discharged from the reservoir (130). The integrated Trickle-MBBR unit (1 ) according to the invention further comprises at least one first trickling plate (210), which enables the water flowing down from said guide (205) to be broken up (dispersed), is located outside the MBBR body (100), is configured below the guide, and comprises at least one hole permitting the passage of the water; at least one second trickling plate (220), which is positioned below said first trickling plate (210) and comprises more than one hole enabling the water coming from the first trickling plate (210) to be transferred into said Trickle body (200) by being homogeneously distributed; at least one support block (240), which is used to guide the Trickle body (200) from the lower part thereof to enable said Trickle body (200) to be kept fixed; at least one gap (250), which is formed between said Trickle body (200) and the floor owing to said support block (240) and permits the exit of the filtered water; and / or at least one hole (230), which is positioned near said floor in the lower part of the Trickle body (200) and permits the exit of the filtered water.

[0070] In addition to these, the integrated Trickle-MBBR unit (1) according to the invention comprises at least one air inlet (20), via which the air enters the MBBR body (100) and which is positioned beside said water inlet (105.2) in the upper part of the MBBR body (100); and at least one venturi (30), which is connected to said air inlet (20) and increases the oxygen level of the water entering the MBBR body (100).

[0071] The water to be subjected to the biological filtration enters via the water inlet (105.2), which is one end of the water pipe (105) and is preferably located in the upper part of the MBBR body (100), and the water is delivered to the lower part of the MBBR body (100) via a water pipe (105), which preferably extends from the upper part to the lower part of the MBBR body (100). Then, said water is transferred in a pressurized state into the MBBR body (100) via a water outlet (105.1), which is another end of the water pipe (105), is positioned in the lower part of the MBBR body (100) in a way to face the upper part of the MBBR body (100), i.e., in a way to be near the reservoir (130) and face the opposite direction from the reservoir, and is preferably configured in the U-shape. Here, the other end of said water pipe (105) is positioned in a way to face the upper part of the MBBR body (100) (to face upward). Thus, as a result of the water to be subjected to the filtration being sprayed upward into the MBBR body (100), the spherical motion through 360 degrees is provided to the biomedia particles inside the MBBR body (100) and the biomedia particles are moved inside the MBBR body (100) to thereby realize their continuous contact with the water to be subjected to the filtration. While the transfer of the water takes place on the one hand via said water inlet (105.2) into the MBBR body (100), the air enters on the other hand the MBBR body (100) via the air inlet (20) positioned beside said water inlet (105.2) in the upper part of the MBBR body (100), and owing to the venturi (30) connected to said air inlet (20), the oxygen level of the water entering the MBBR body (100) is increased and thus the efficiency of the biological filtration is improved. Said water outlet (105.1) is supported with the help of a pipe holder (111 ). Said pipe holder (111) is connected to the upper part of the reservoir (130) positioned below the MBBR body (100).

[0072] The MBBR body (100) contains the biomedia. The water to be filtered, which is transferred in a pressurized state into the MBBR body (100) via the water outlet (105.1 ), sets the biomedia inside the MBBR body (100) in motion. After the water to be filtered moves upward, i.e., moves to the upper part of the MBBR body (100), the biological filtration is realized as a result of the interaction of said water with the biomedia inside the MBBR body (100), and then, upon settling down, the water enters the reservoir (130) located below the MBBR body (100), via the slits and / or holes present on said reservoir (130). The slits on the reservoir (130) may be in the form of gratings preferably configured as elongated slits. The holes, preferably with a circular shape, are present on the sides within said reservoir (130). The water with completed biological filtration accumulates inside said reservoir (130) and the water processed inside the MBBR body (100) is moved towards the upper part of the MBBR body (100) with the help of at least one pipe (140), which starts inside said reservoir (130) and extends to the upper part of the MBBR body (100). There are preferably four pipes (140) and these are kept fixed with the help of the holder tips (142.1 ), which are located in the end portions of the holder (142) in the upper part of the MBBR body (100) and are configured to grip each pipe (140).

[0073] As can be seen in Figure 13 providing a view where the guide (205) is hidden, an end portion of the pipe (140) located in the upper part of the MBBR body (100) protrudes via an opening on the MBBR body (100). In other words, while an end of said pipes (140) is positioned inside the reservoir (130) below the MBBR body (100), another end of the same protrudes from the MBBR body (100) via an opening in the upper part of the MBBR body (100). The water moving up via the pipes (140) to the upper part of the MBBR body (100) is transferred to the Trickle body (200) from at least one guide (205), which is positioned opposite said other end of said pipes (140) protruding from the MBBR body (100). Said guide (205) is configured outside the MBBR body (100) preferably by way of connecting together four semi cylindrical structures. The water flowing down from said guides (205) is transferred to, i.e., poured in, the first trickling plate (210) located in the upper part of the Trickle body (200). Said first trickling plate (210) is preferably connected to the outside of the MBBR body (100) and preferably contains circular holes. In another embodiment of the invention, the first trickling plate (210) includes thereon at least one slit and hole preferably in the rectangular shape and it is possible to increase the numbers of the slits and the holes. A wall, which extends upward, is configured on the sides of the first trickling plate (210). Owing to said wall, the water transferred to the first trickling plate (210) is prevented from overflowing the side portions. The water flowing from the guide (205) and reaching the first trickling plate (210) trickles through the holes present on the first trickling plate (210) and is thus transferred to the second trickling plate (220). The water transferred in the form of a bulk from the guide (205) is broken up (is enabled to disperse) with the help of the first trickling plate (210) and it thus acts with a greater surface area. The water trickling from the first trickling plate (210) is transferred to the second trickling plate (220), which is positioned below the first trickling plate (210) and which is preferably connected to the outside of the MBBR body (100) to surround said MBBR body (100). Here, the holes and the slits on the first trickling plate (210) are positioned such that the water will fall down at or near the center of the second trickling plate (220). In this way, the water is enabled to be equally distributed from the first trickling plate (210) to the second trickling plate (220). The second trickling plate (220) has a wider diameter compared to said first trickling plate (210) and the holes on the second trickling plate (220) are configured to be present in a number greater than the number of holes located on the first trickling plate (210). In another preferred embodiment of the invention, in addition to the holes, the elongated slits may also be present on the second trickling plate (220). A wall, which extends upward, is configured on the sides of said second trickling plate (220). Owing to said wall, the water transferred to the second trickling plate (220) is prevented from overflowing the side portions.

[0074] The water trickling down through the holes on the second trickling plate (220) trickles, in a manner similar to the raindrops, down the Trickle body (200), which resembles a tank filled with bioballs (spheres formed by small tubes providing a wide surface area where the microbes filtering the water may grow). Inside the Trickle body (200), the water is broken up by way of being trickled down through the first trickling plate (210) and the second trickling plate (220), and thus, the water is enabled to contact more air and bioballs inside the Trickle body (200) and is freed from the undesirable gases. Owing to the first trickling plate (210) and the second trickling plate (220) on the Trickle body (200), a two-stage degassing process is realized. The Trickle body (200) is kept fixed by way of guiding said Trickle body (200) from the lower part of said Trickle body (200) with the help of at least one support block (240), and owing to said support block (240), a gap (250) is formed between said Trickle body (200) and the floor. The Trickle body (200) and therefore the MBBR body (100) are located on said floor. After the water with completed biological filtration inside the MBBR body (100) is transferred to the Trickle body (200) and is also subjected to the two-stage degassing process, said water is discharged via said gap (250). When said gaps (250) are not sufficient for the discharge of the water, it is possible to realize the discharge of the water via at least one hole (230), which is positioned in the lower part of the Trickle body (200) to prevent the clogging of the system and via which the water separated from the undesirable gases is discharged. Preferably, the number of said holes (230) may be increased and they may be arranged at intervals along the perimeter of the lower part of the Trickle body (200). While the water is being discharged via said bottom holes (230) and gap (250) to be transferred to the other filtration units, the bioballs present inside the Trickle body (200) are not able to pass through said bottom holes (230) and gap (250). Thus, while an effective filtration process occurs, the clogging of the system is also prevented.

[0075] In a preferred embodiment of the invention, the water coming from the protein skimmer is also transferred to the Trickle body (200) in order to realize the separation of the same from the undesirable gases. As shown in Figure 5, the water coming from the protein skimmer is transferred to the second trickling plate (220) of the Trickle body (200) via the protein skimmer water inlet (310) located in the end portion of the pipe leading from the protein skimmer (300). Then, the water coming from the protein skimmer is enabled to trickle down into the Trickle body (200) via the holes present on the second trickling plate (220), and thus, said water coming from the protein skimmer is also enabled to be separated from the undesirable gases. Consequently, with the integrated Trickle-MBBR unit (1) provided by our invention, the water is pumped by means of a single pump and the overall area occupied by the unit is reduced. Here, the filtration processes are performed simultaneously via two separate systems by pressurizing the water via said water pipe (105) and circulating said water through the integrated Trickle-MBBR unit (1). When the MBBR body (100) and the Trickle body (200) are used separately as in the state of the art, an extra pump is needed to pump water to each body and the extra piping cost is also added. Moreover, the occupied area becomes greater when each body is positioned separately. As a result, owing to the Trickle body (200) housing the MBBR body (100), the overall area occupied by the unit and the footprint are reduced.
