Electro-chemical Treatment of Shrimp farm Wastewater effluent using Electro coagulation flotation Systems


Global shrimp consumption is on the rise. Also, shrimp, being the single most valuable seafood commodity in international markets, creates the competition.

The competition now boils down to who can mass produce without sacrificing quality and harming the environment. Shrimp farm Owners, now, should comply and must meet the necessary requirements and should practice recycling the effluents from shrimp farms. This force Shrimp farm owners for the integration of effluent treatment system as a part of the shrimp farm to improve waste water quality.

Shrimp farm effluent consists - uneaten food pellets, feces and eroded pond soil with varying levels of Total Ammonia Nitrogen (TAN), Nitrite-Nitrogen (NO2-N), Nitrate-Nitrogen (NO3-N), Total Phosphorus (TP), Dissolved Orthophosphate (PO4-P), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), Chlorophyll-a (Chl-a), Temperature, Salinity, pH and Dissolved Oxygen (DO). The higher concentration of these parameters makes the shrimp farm effluent more toxic when discharged to environment without treatment.

Shrimp pond effluent are rich in organic matters, which potentially pollute the adjacent waters and negatively impact local and regional environments in various ways.

Thus, water treatment process for shrimp farm effluents is potentially considered as a means to reduce the impacts on the surrounding environment.

RT ECO Hybrid Systems for Shrimp farms effluent treatment

RT ECO, Advanced Hybrid, Wastewater Treatment technology, has made it considerably easier, for shrimp farm owners to reuse water and also meet the consequent stringency in environmental legislation.

RT ECO ETP systems are developed and applied with the Electro coagulation, flotation and Oxidation technique, to treat and reuse water for shrimp farms. RT ECO ETP Systems, removes, ammonia nitrogen to the lower level than the toxic level, convert toxic ammonia and nitrite to less toxic nitrate and keeps the pollutants within safe limits after each cycle. RT ECO, advanced wastewater treatment systems uses smaller footprint and requires 90 to 95% less space than conventional plants. Reduces labor requirements and can be automated easily.

The wastewater after treatment is safe to reuse, for re-circulation again, or safe to release it in any nearby water bodies after seasons, without causing any harm.
