PENYISIHAN COD, BOD, TSS, AMMONIA MENGGUNAKAN PROSES BIOFILTER TERCELUP DENGAN MEDIA BIOBALL SECARA AEROB (Studi Kasus Air Limbah Domestik Waduk Setiabudi Jakarta Selatan)

Abstract

Denseness of settlement and bad condition of environment sanitation, and also the outcast of wastewater that is removed to water organ directly without manufacture process have been caused river pollution in Jakarta. The main source of pollution in the Jakarta is domestic’s waste water ( ± 80%), where as an industrial waste water giving contribution just 20%. Something to do to manufacturing the domestic wastewater is with Submerged Biofilter. This research used to manufacturing the domestic wastewater so that can be safe for the environment; know about the influence of hydraulic retention time’s variation andrecirculation rasio for the efficiency of domestic wastewater manufacture usingsubmerged biofilter with bioball’s media in aerob by the parameters of BOD, COD, Ammonia, and Total Suspended Solid ( TSS). Sample that it use is domestic waste water from one of inlet in Setiabudi’s reservoir at South of Jakarta. From the result of a research, can be find the shortest hydraulic retention time is 6 hours with the COD’s efficiency value are 78,42%, BOD value are 79,41%, ammonia value are 61,41%, TSS value are 82,06%. Besides that, the most effective of resirculation rasio is 0,5Q. With resirculation rasio 0,5Q, the waste efficiency of COD are 82,42%, BOD are 83,11%, TSS are 83,38% and ammonia are 78,45%. Effluent result of domestic wastewater manufacture using submerged biofilter with biobal’s medial in aerob have been safely if removed to water organ because it is suitable enough with the standard of domestic waste water based on the DKI Jakarta’s governor regulation number 122 in years of 2005 about Domestic Wastewater execution in the Provinsi DKI Jakarta.
