Abstract

Almost in every city in Indonesia there are many home-scale tempe industries. These industries have not yet treated their waste, which has resulted in river water pollution. Limited funding becomes an obstacle when industrial owners build wastewater treatment facilities. The construction of an appropriate and cheap wastewater treatment facility will be of great benefit to them. The combination of an aerobic reactor and biofilter media is a biological waste water treatment process using filter media. This study used an aerobic system with the variations used were detention time for 24, 48, 72, 96, 120 hours and a combination of a consortium of microorganisms. The parameters analyzed were BOD, TSS, and TDS. From the research, it was found that the optimal removal efficiency with a consortium of microorganisms in reactor A with a residence time of 120 hours and the final results were BOD 95.58%, TSS 24.82%, and TDS 48.95%.

Abstract

This research uses anaerobic biofiltration with various types of media and residence time in a batch system. The purpose of this study was to determine the effectiveness of the anaerobic biofilter reactor in degrading the pollutant load and to find the variation of media type and the best residence time to be continued into a continuous system. From this study, the optimal results obtained in the batch system were BOD 87.4%, COD 89.2%, TSS 87.5% with a residence time of 16 days on the type of bioball media. However, NH3-N cannot be removed under anaerobic conditions, so NH3-N is effective at a residence time of 0 days with an efficiency of 34%. The percentage of removal in the continuous system is stable, that is, the average removal efficiency of BOD is 85.8%, COD is 87.1%, and TSS is 75.8%.

Abstract

The volume of waste is directly proportional to the increase in population. Thus, the level of public consumption used in daily life for materials also increases. The more waste generated, the need for land expansion. Currently, TPA Kedungdowo receives waste residue from TPST Kartoharjo in 2020 amounting to 497,655 Kg/year. This study aims to make a Service Expansion Plan for TPST Kartoharjo Kab. Nganjuk. The waste generated by the Kartoharjo TPST is 32683 kg/day. With the number of Sukomoro District as much as 6941 kg/day, Nganjuk District as much as 17648 kg/day, Bagor District as much as 8094 kg/day. The land area used for the expansion of the TPST is 1048.76 m2 .
