Studies of the Effectiveness of Wastewater Treatment Systems at Local Companies Waste Water Management of the City of Banjarmasin

Abstract

Wastewater disposal is a major problem in this developing country. The largest source of liquid waste in this country is the result of household activities. This study aims to analyze the effectiveness of the Pekauran Raya and Basirih wastewater treatment plant (IPAL) at the Banjarmasin Municipal Wastewater Management Company. This type of research is quantitative descriptive. The technique of collecting data is by observing WWTP and measuring the effectiveness of wastewater treatment on BOD, COD, and TSS parameters. The research location uses the purposive sampling technique. Data analysis used the calculation of the effectiveness of the parameters on the WWTP. The results showed that the concentrations of BOD and COD decreased from inlet to outlet, namely BOD from 20.4 mg/l to 18.4 mg/l at Pekapuran Raya WWTP, while Basirih WWTP from 23.5 mg/l to 18.4 mg/l. l. COD parameter in Pekapuran Raya WWTP from 57 mg/l to 53 mg/l while Basirih WWTP from 60 mg/l to 52 mg/l. The TSS parameter was still above the threshold of the two WWTPs, namely the Pekapuran Raya WWTP from 71.6 mg/l to 63.2 mg/l and the Basirih WWTP from 79.2 mg/l to 64.2 mg/l. The effectiveness level of the two WWTPs, namely Pekapuran Raya and Basirih WWTPs with BOD, COD, and TSS parameters showed that the concentration of the average effectiveness level decreased in each parameter. In reducing the concentration of WWTP Basirih, it was higher seen from the effectiveness of reducing BOD, which was 21.7%. Suggestions need to be done again to check the TSS concentration in the WWTP does not exceed the quality standard threshold, so that it is useful for determining the effectiveness of wastewater treatment.
