A waste treatment plant integrated with treated water recycle, biogas energy recovery, plus solids stabilization and reuse has been constructed in 1985 on a 20,000 standing pig population (SPP) farm. The plant incorporates biotechnologies developed under R&D Projects in the Primary Production Division (PPD) of Singapore with grants from the United Nations Development Programme (UNDP), the Australian Development Assistance Bureau (ADAB), the International Development Research Centre (IDRC) of Canada, the Food Waste Materials Utilization Project of the Association of Southeast Asian Nations (ASEAN) and the technical assistance of the Food and Agriculture Organization (FAO) of the United Nations. The treatment processes include biogas digestion, chemically aided sedimentation, modified anaerobic lagoon, solids dewatering through sand filters and centrifuge, oxidation ditch aeration basins, etc. The aim of the Project is to determine the technical requirements and costs of producing effluents of 250 mg/l and 50 mg/l BOD integrated with resource recovery and resue.
