EVALUASI KARAKTERISTIK AIR LIMBAH HASIL PENGOLAHAN WASTE STABILAZION POND DI KOTA JAKARTA

Abstract

Total Suspended Solids Abstract The city of Jakarta is a metropolitan city that cannot be separated from environmental problems such as the generation of domestic wastewater. One of the domestic wastewaters in the city of Jakarta is treated with a centralized system and treated with a waste stabilization pond (WSP). Increasing the number of services and changing wastewater characteristics can affect WSP performance. The purpose of this study is to evaluate the performance of wastewater treatment with WSP in the city of Jakarta. The measurements were carried out at the inlet and outlet of the WSP system and based on the parameters of Biological Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), pH and Ammonia. Based on the standards set by the Indonesian government, all of these parameters have met the quality standards. Efficiency of removal of parameters BOD, COD, TSS, ammonia is 96.22% respectively; 88.66%, 96.19%, 98.62%. The pH of the processing is also in a neutral pH condition, namely 6.5-8.5. The results of the treatment with WSP can be said to be going well and efforts are needed for continuous improvement such as planning for the reuse of treated water.
