The study used fermentation waste – sorghum distillery residue (SDR) as a precursor. SDR ash were prepared by combusted directly, and SDR activated carbons (SDRAC) were activated by the method of physics activation with steam. The feasibility of purifying into irrigation water with SDRAC from the effluent after the treatment was investigated. The pH value of alkaline water with different weight percents of SDR ash was about 11.20, and of the SDRAC was between 9.39 and 10.09. The alkaline water impregnated with SDRAC was effective to the alkalizing wine factory sewage and as a role of precipitation process. The suspended solids for the purifying into irrigation water remove about 56 to 77%. The chemical results of chemical oxygen demand, biochemical oxygen demand, nitrate nitrogen, and ammonia nitrogen were removed about 39–90, 58–65, 68.0–97, and 1–21%. The metal and trace elements in water showed that heavy metals, Cr, Pb, Zn, Cd, Ni, Cu, Hg, removed 28–99%, and 31–99%. The results of total bacterial count, coliform group and total organic carbon were about 98.2, 58.6 and 32.4%, respectively. The alkaline water of SDR ash can be replaced the alkalization for sewage precipitation process, and SDRAC is one of the potential filters to purify effluent into irrigation water.
