Fluidized Bed Biofiltration

Bio-Filter

Treatment

This paper shows the results of the efficiency of a circulating fluidized bed biofiltration system using polyetheleneas a filtering material. Changes in water quality parameters and the growth rates of shrimp (broodstock and commercial production) were used to assess the efficiency of water treatment system. The concentration of NH4+in waste water from the broodstock tanks decreased 61% after three months of treatment. The final concentration of NH4+after treatment was 0.07 mg/mlwhich meet the Vietnamese regulations for discard of aquaculture waste into coastal waters. Biological oxygen demand decreased 48%. The corresponding figures for treating waste water from commercial shrimp tanks were decreases of NH4+by up to 61% with outlet concentration 0.07mg/ml accepted to discard according to Vietnamese Standard and biological oxygen demand by 55%. Outlet water providingfrom broodstock and commercial shrimp tanks were treated with COD concentration decreased from 3.12 down to 2.62mg/ml and 4.62 down to 2.68 mg/ml, or 16% and 41.9% of COD removal, respectively.
