PENYISIHAN KANDUNGAN PADATAN LIMBAH CAIR PABRIK SAGU DENGAN BIOREAKTOR HIBRID ANAEROB PADA KONDISI START-UP

Abstract

Sago Liquid waste increased with the development of sago industry in Indonesia. Sago liquid waste is acidic, foul-smelling and has a high concentration of solids. Solids is one of the parameters in the identification of a wastewater pollution levels. Sago mill waste water solids can be organic and inorganic solids. Organic solids can generally be degraded by microorganisms, while inorganic solids difficult degraded by microorganisms. Therefore, it is necessary sago wastewater treatment before discharge into water bodies or water. Handling of solid sago mill waste water can be done using the anaerobic bioreactor of media anaerobic hybrid rocks. The success of this bioreactor in treating wastewater depends on the strategy of start-up bioreactor. This study aimed to isolate and get the reduced rate of sago wastewater solids content at start-up conditions. The results showed that the start-up of hybrid anaerobic bioreactor lasts for 58 days with WTH 2 L / day, operating conditions at room temperature and pH of 6.2 to 7.1 average. TS removal efficiency by 63,87%, TVS by 43,75%, TSS by 60,63% and 61,76% VSS. This shows that the hybrid anaerobic bioreactor mediated in both rock solid content aside sago mill waste water
