Evaluasi Kinerja Unit Instalasi Pengolahan Air Limbah Bojongsoang Bandung

Abstract

Wastewater treatment is required in order to improve waste water quality in accordance with the water quality standard and not harm the environment. The purpose of this research were to determine the quality of waste water based on BOD, COD, TSS, and pH parameters in the influent and effluent of each unit of wastewater treatment plant (IPAL), to compare the efficiency in reducing pollutant concentration with the literature, and comparing the quality of waste water at outlets with water quality standards. The research used samples taken in IPAL Bojongsoang Bandung and the test were done at PDAM Bandung laboratory. The highest efficiency of pollutant reduction in unit set A for TSS parameter was 66.67%, BOD 87.55%, and COD 81.28%. While for unit set B the biggest pollutant reduction efficiency for TSS parameter was 55.88%, BOD 73.91%, and COD 73.05%. The processing unit set A had been eligible for BOD and COD parameters for oxidation ditch (80-90%). Concentrations at outlets in unit set A for TSS was 50 mg/l, BOD 27 mg/l, COD 67 mg/l, and pH 6.5, while in unit set B TSS was 75 mg/l, BOD 21 mg/l, COD 45 mg/l, and pH 6.5. Comparing to the water quality standard the value of COD and pH had fulfill the standard.
