Abstract
White leg shrimp (Litopenaeus vannamei) farming effluent contains pollutants that include high levels of total suspended solid (TSS), chemical oxygen demand (COD) and growth promoting substances. This study investigated the possibility of using artemia to filter suspended solids and Tilapia (Oreochromis niloticus) to consume organic waste of shrimp, uneaten food at the bottom of wastewater tanks of industrial shrimp farming. Both artemia and Tilapia had the ability to rapidly reduce organic matter content in wastewater of industrial shrimp farming in tanks. This contributed to reducing total suspended solid in wastewater when discharged into the environment. The biochemical oxygen demand (BOD₅), chemical oxygen demand (COD), total suspended solid (TSS) met effluent standards in Circular No. 44/2010/TT-BNNPTNT and QCVN 11-MT:2015/BTNMT in all of the investigated plots. In the surface wastewater of wastewater tanks, the remaining TSS, BOD₅, and COD contents were the lowest at 6.2 ± 1.1 mg/L, 3.9 ± 0.5 mg/L, and 8.6 ± 1.4 mg/L, respectively, in the stocking density of 300 artemia individuals/L. In the bottom wastewater, the remaining TSS, BOD₅, and COD contents were the lowest at 21.4 ± 5.1 mg/L, 8.5 ± 1.5 mg/L, and 11.6 ± 3.6 mg/L, respectively, in the stocking density of 16 Tilapia individuals/m3.
