ANALISIS KANDUNGAN BOD, TSS DAN MPN COLIFORM PADA AIR LIMBAH DENGAN PENGOLAHAN SISTEM KOMPAK DI RSUD PROF. DR. W. Z. JOHANNES KUPANG TAHUN 2008

Abstract

The effluent wastewater of the hospital has certain physically, chemically, biologically characteristics. The aim of study were:1) to know the content of BOD, TSS and Coliform MPM at wastewater processing using a compact system at RSUD Prof. Dr. W.Z. Johannes Kupang and 2) to analyze the difference between BOD, TSS, and MPN Coliform content before and after processing.  The sample of the study was part of the wastewater effluent released by RSUD Prof. Dr. Johannes that was taken at the inlet before processing and at the outlet after disinfection processing.   Tree samples of effluent were taken daily at 10 o’clock am. Inlet and outlet for 7 days. So the total number of samples was 42. The volume of each wastewater effluent sample was 250 ml. There were tree parameters that had been analyzed, those were BOD, TSS and MPN Coliform content. The collected data were analyzed statically using Kolmogorov Smirnov test to know the normality of the data and t-test analysis was used to know whether there was the difference between before and after processing for the three selected parameters. The “Keputusan Menteri Lingkungan Hidup No. 58 Tahun 1995” was used as a standard in valuing those three parameters.
