What is the importance of chemicals for wastewater treatment in the seafood industry? Aquatic wastewater produces a fishy odor due to the decomposition process of the remaining parts of marine organisms, which seriously and directly affects the human living environment if not treated properly. A wastewater treatment system using chemical and biological methods is considered standard and highly effective. In particular, the presence of chemicals for wastewater treatment in the fisheries industry plays an essential role and cannot be ignored. Because wastewater from the seafood processing industry contains mostly organic waste of animal origin, the main components are proteins and fats. Of these two components, fat is the most difficult to decompose by microorganisms. What is the importance of chemicals for wastewater treatment in the seafood industry?

Because wastewater from the seafood processing industry contains mostly organic waste of animal origin, the main components are proteins and fats. Of these two components, fat is the most difficult to decompose by microorganisms. Suspended solids make water cloudy or colored, organic substances contained in seafood processing wastewater, high concentrations of nitrogen and phosphorus... All of the above phenomena have negative impacts on water quality, affecting aquatic systems, aquaculture, tourism and water supply. Therefore, building a wastewater treatment system and using chemicals to treat it to avoid contaminated water sources or infectious agents will transmit diseases to humans such as dysentery, urinary tract infections, acute diarrhea, typhoid, polio... Treating aquaculture wastewater with chemical methods Currently, wastewater treatment technology in aquaculture using biological and chemical methods is preferred by many businesses because of its effectiveness and ease of operation. onions. This method will be used in case of late season harvest. Due to the capacity of the wastewater treatment system, it cannot contain all the wastewater discharged at one time, and it is also not possible to store water for 15 days as required. Therefore, it is necessary to have a specific plan for each harvest, which must be divided into at least 3 to 4 batches, each batch of discharged wastewater is stored in the system for at least 24 hours. This is done simultaneously with supporting treatment with common industrial agglomeration chemicals such as: Al2(SO4)3, Fe2(SO4)3 concentration 1÷5 g/m3 wastewater). Situational solution: In case of disease, do not drain water into the common drainage channel, the diseased pond will be treated separately. The treatment process includes: Use CaOCl2 concentration 5÷10 mg/liter to fertilize the diseased pond, then discharge into the wastewater treatment system. After each crop, the pond is drained and the mud layer on the surface is dredged.
