Floating bioadsorbent materials for the treatment of phosphate and nitrate contamination in water, and their manufacturing process.

Abstract

------30 / 01 / 2569------(OCR) OCR 09WP This invention relates to a floating bioadsorbent material for the treatment of phosphate and nitrate contamination in water. It consists of high-temperature calcined clam shells, soda-lime glass powder, dolomite clay, and is immobilized with microorganisms. The manufacturing process involves several steps: mixing soda-lime glass powder, dolomite clay, high-temperature calcined clam shells, and water; granulation; high-temperature calcination to create pores; sterilization of the pores; and sterilization of the lightweight porous adsorbent with microorganisms. This simple process allows for production on both small and large scales. The resulting floating bioadsorbent is effective in the treatment of phosphate and nitrate contamination in water, representing a cost-effective and highly efficient use of the material.

2. A floating bioadsorbent for the treatment of phosphate and nitrate contamination in water, according to claim 1, which is immobilized with effective wastewater treatment microorganisms.

3. A floating bioadsorbent for the treatment of phosphate and nitrate contamination in water, according to claim 2, where effective water treatment microorganisms can be selected from the group of Pseudomonas sp., Pseudomonas aeruginosa, Bacillus sp., Bacillus megaterium, and microorganisms contaminating the absorbent material after phosphate and nitrate treatment.

4. Floating bioadsorbable material for the treatment of phosphate and nitrate contaminants in water, as per any one of claims 1 through 3, which is cylindrical in shape, 1.5 centimeters long and 0.5 centimeters in diameter.5.The process for producing floating bioadsorbable materials for the treatment of phosphate and nitrate contamination in water, as per any one of claims 1 to 4, consists of the following steps: a. Raw material preparation: Clam shells are washed, dried, and calcined at a high temperature of 700-900 degrees Celsius. They are then finely ground and sieved to obtain clam shell particles no larger than 74 micrometers. Soda-lime glass powder and dolomite are also prepared by drying and sieving to obtain particles no larger than 74 micrometers. b. Production of lightweight porous absorbent material: The raw materials from step a are used...Mix the raw materials thoroughly with water, using a ratio of 100 grams of total weight of raw material powder to 5-10 milliliters of water to ensure a homogeneous mixture. Use a weight ratio of soda-lime glass powder, dolomite clay, and clam shell powder in the range of 75-85%: 10-15%: 5-15%, respectively. Then, compress the mixture into molds to obtain granular absorbent material. Heat the absorbent material at 60-70°C for 24-48 hours, then calcin at 700-800°C for 10-30 minutes. Allow to cool. Shake the lightweight porous absorbent material in a closed container to remove any remaining powder from the pores. Sterilization: Sterilize the lightweight porous absorbent material obtained from step b using a steam-pressure autoclave, and then dry the material. Development of a lightweight, biodegradable porous adsorbent material by utilizing the lightweight porous adsorbent material obtained from step C.

6. A process for producing floating bioadsorbable material for the treatment of phosphate and nitrate contamination in water, according to claim 5, which requires the adsorbent material to be cylindrical in shape with a length of at least 1.5 centimeters and a diameter of at least 0.5 centimeters.

7. A process for producing floating bioadsorbable material for the treatment of phosphate and nitrate contamination in water, according to claim 5(d), which requires the use of effective wastewater treatment microorganisms selected from the groups Pseudomonas sp., Pseudomonas aeruginosa, Bacillus sp., Bacillus megaterium, and selected from the group of microorganisms contaminating the adsorbent material after phosphate and nitrate treatment.

8. A process for producing floating bioadsorbable material for the treatment of phosphate and nitrate contamination in water, according to claim 5(d).Alternatively, method 7, where aseptic technique involves sterilization in a steam-pressure sterilizer, is used. This involves packing lightweight, porous absorbent material into heated plastic bags, placing them in a steam-pressure sterilizer, heating to 121 degrees Celsius and applying a pressure of 15 pounds per square inch for 15 minutes.
