Abstract |
An efficient pretreatment of piggery wastewater would be an essential for the successful secondary treatment due to the high concentration of suspended solids(SS) and Biochemical Oxygen Demand (BOD). To evaluate an efficient pretreatment process for the diluted piggery wastewater treatment, the sedimentation process and the filtration process were considered. Results indicated that, the filtration process which adopted dried rice straw as a medium was an effective method to remove the SS and soluble BOD. In addition. the removed rice straw medium would be an adequate bulking agent for the composting process. |
