Konsep Desain Instalasi Pengolahan Air Limbah Skala Komunal Dalam Rangka Purifikasi Kualitas Air Sungai Di Jakarta

Abstract

The decreasing of the rivers quality in Jakarta caused by no installation of communal wastewater treatment. Therefore, the examination of river quality was conducted to determine the level of water pollution in the estuary and to formulate basic concepts of communal Wastewater Treatment Plant (WWTP) design alternatives. Generally, the scope of the research is divided into two analyses. The first stage is to analyze the chemical and biological quantitative water sample at 10 points of the river estuary for domestic wastewater and one point of PT. “X” effluent for industrial wastewater. The second stage is to analyze the alternatives of WWTP design. According to “SK Gubernur DKI Jakarta Nomor 582 Tahun 1995” about determination of the designation and river water quality standards for raw water and wastewater, the results of river water quality monitoring for class D of raw water as urban and agricultural activity does not meet quality standards, in particular the parameter COD (11.54-106.54 mg / l), BOD (10.32-88.2 mg / l), Coliform (90,000-570,000,000/100 ml) and Fecal Coli (47,833-431,000,000/100 ml). One of the solutions for reducing pollutants is constructing the communal Anaerobic Baffled Reactor (ABR) for domestic wastewater and the small WWTP for industrial wastewater.
