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
