The increasing production of shrimp through super intensive aquaculture is followed by high concentrations of nutrients in wastewater discharged to the surrounding waters. The Intensive shrimp ponds in Takalar Regency developed wastewater treatment plant to reduce concentrations of nutrients in the effluent before releasing to the adjacent waters. This study was aimed to analyze the performance of wastewater treatments of super intensive L. vannamei shrimp developed in Takalar Regency.

The study was conducted in Research Installation for pond aquaculture in Takalar Regency, South Sulawesi, Indonesia. The effluent discharged from three 1000 m2 intensive shrimp ponds were settled then oxygenated before the effluent flows to bioconversion tanks then stored in a bioassay pond then released to the receiving environments. The analyses of nutrients in the inlet and outlet of wastewater plant were conducted every week for TSS, pH, DO, BOD5, PO4 and TAN.   

The results of this study indicated the decreased in concentrations of TSS, DO, BOD5, and PO4; whereas the effluent released to the receiving waters was in the base state compared that measured in inlet which was in acid state. The concentrations of TAN, in contrast the wastewater plant did not reduce concentration of TAN, yet the concentration of TAN increased at the outlet. The concentrations of TSS, DO and BOD5 in the outlet were in the accepted concentrations threshold regulated by the Indonesian Government; in contrast, the improvement in reducing concentrations of PO4 and TAN should be conducted as concentrations of these nutrients exceeded the concentrations threshold standardized by the Indonesian Government (Table 1).
