Evaluation of the effectiveness of wastewater treatment plant for super-intensive shrimp farms (A case study on Punaga Village, Takalar)

Abstract

Abstract Wastewater becomes a problem if it is not appropriately treated. Shrimp farms are one of the examples of an industry that produces wastewater. Super Intensive farms usually have a high concentration of wastewater pollution and above the threshold required. Therefore, this study aims to evaluate wastewater changes from super-intensive farms to wastewater treatment plants (WWTP) and evaluate the effectivity of WWTP to treat the wastewater. The study was done through laboratory texting (ex-situ) and field (in-situ). This type of research using the descriptive method, describing the characteristics that systematically determined. This study uses purposive sampling method and integrated sampling for six weeks in the Wastewater Treatment Plant (WWTP) unit and raw water from the reservoir of a super-intensive pond. Research has been conducted from May to June 2016. The result found that the effluent of wastewater from super-intensive farms tends to increase or contaminated with pollutants such as waste metabolites, un-eaten nutrient waste by fish, and waste detritus. Based on optimum standards of environmental sanitation by the Ministry of Health in 2011, it shows that the effectiveness is more likely to decrease the pollutant (already efficient: 60% < x = 80%). The effe ct ive ness o f TSS parameter is efficient enough by 63.4%, TN 60.0%, Phosphate (PO4) 59.21%, 64.07% BOD. Nevertheless, the effectiveness of TOM parameter based on the optimum standards allowed by the Ministry of Environment 51 2004 is 15.45%, which is inefficient (x = <20%); the parameter of pH is 3.67% and DO 17.01%. Both parameters of pH and DO are more likely to increase or quite efficient. According to KEP28 / MEN / 2004 regarding Shrimp Effluent Quality standards and the results bioassay test, there were 100% of Survival Rate (SR), and it was in good condition for the medium term for 96 hours (4 days).
