Waste water from the coconut jelly processing stages, is leading to an air conditioning but after going through trash, garbage is separated here removed from the wastewater. Swimming conditioned stable functioning waste flow and concentrations of pollutants in wastewater. After waste water has been stable in line with the growth of micro-organisms, sewage is pumped into the aerobic biological tank. With aerobic microorganisms will decompose adhesion of organic matter remaining in waste water and use this organic matter in order to develop biomass. After performing the decomposition process in an aerobic biological waste water is released into a settling tank activated sludge generated in the biological treatment process. Sludge from the settling tank is pumped out to decompose sludge to compost. After waste water through settling tanks relatively clean in terms of quality standards for the receiving water. However, in order to thoroughly eliminate the bacteria that can cause disease in wastewater, such as E. coli, coliform, ... waste water is directed through exposure Chlorine tank before flowing into the receiving water, type B standards (TCVN 5945-2007).
