Organic Waste Reduction by Co-digestion of Slaughterhouse Wastewater and Domestic Sludge
Author(s): Salah SB Dababat*
This research was executed to investigate the reduction of the volatile and solid matter in the Co-digestion of
slaughterhouse wastewater (SHW) with primary sludge (PS). Lab-scale experiment was executed at mesophilic
condition (35 ± 2°C). 600 ml serum bottles were used to mimic batch bioreactors. Among others total solids content
(TS), volatile solids (VS) were measured before and after the digestion process. In addition to recording the daily
biogas and methane production.
The experiment showed that PS achieved maximum volatile solid reduction (49%), while the organic stabilization
percentage of each SHW and Co-digestion mixture (Co) were 29.1% and 44.4% respectively. The solid stabilization
was at maximum value (63%) at PS reactor compared to SHW and co-reactors (39.5% and 49.8% correspondingly). .. View more»
