Pengaruh Hrt Dan Kosentrasi Terhadap Produktivitas Biogas Pada Pengolahan Air Limbah Greywater Artificial Menggunakan Reaktor Uasb (Studi Kasus : Perumahan Bsb Dan Pemukiman Gabahan Semarang)

Abstract

The ever-increasing human activities that produce a lot of waste water. If this is not processed will result in a body of water pollution. So an effective treatment is needed and appropriate. Anaerobic treatment can reducing concentrations of wastewater and produce a final product in the form of biogas. The technology used is uasb. This technology has considerable efficiency and does not require extensive site. UASB technology has been spread all over the world and many are used for handling various kinds of waste.This research was conducted with variations of the HRT and concentration to see the productivity of biogas. Allowance of COD to the productivity of biogas on domestic wastewater treatment (grey water) at the optimum condition is obtained as follows: at high concentration with HRT Variation 4, 8, and 10 hours respectively allowance of COD (413.47 mg/ l, 624.57 mg/ l, mg and 700.15 mg/ l) and volume of Biogas (30,74 ml 58,89 ml, and 56,26 ml). At concentrations being high with variations of HRT 6 and 12 hours respectively allowance of COD (402,72 mg/l, and 590 mg/l) and a Volume of Biogas (46,93 ml and 27,85 ml) maximum conditions at high concentration with HRT 4 hours with the allowance of 413,47 mg/l COD and Biogas Volume 58,89 ml. The result is quite different from research by concentration of the cod more than 100,000 mg / l produce 4.59 l / day biogas
