Utilization of Bottom Ash Coal and Agarwood in Waste Water Treatment in Palembang Jumputan Fabric

Abstract

Waste containing dyes causes visual pollution and increase the risk of environmental and health issue. The aim of this study was to determine the best operating conditions of jumputan liquid waste treatment using bottom ash batubara and agar wood with variations in feed flow rate (1, 2, and 3 l/min), filtration time (30, 60, 90, and 120 mins), and treatment. The results are compared with the parameters of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), and pH of clean water quality standards for jumputan industry businesses and/or activities regulated in the Governor’s of Sumatera Selatan Regulation Number 16 year 2005. The initials analysis of jumputan liquid waste before processing showed that jumputan liquid waste did not meet these quality standards, except pH and turbidity levels. In this study, jumputan liquid waste was pretreated using coal bottom ash and activated carbon, then filtered. Biodegradation of jumputan liquid waste by conventional method. The best of BOD, COD, TSS, pH, and the percentage of color rejection in the study were obtained in the treatment of jumputan liquid waste using bottom ash batubara and activated carbon at 120 minutes filtration time and a 1 l/minute feed flow rate namely BOD 5.98 mg/l, COD 15 mg/l, TSS 22.3 mg/l, pH 7.32, color 5 Pt-Co, and 0 NTU turbidity. The filtration with bottom ash coal and agar wood can removed the coloring from dyes.
