%X The food processing industries usually produced large amount of wastewater containing fine and small particles. It takes long time for complete settlement of the fine and small particles in the wastewater. The coagulation method appears to become one of the useful treatments. New inorganic coagulant named ˇ°Agoclean Pˇ± has been developed from paper sludge ash. The treatment by coagulation and flocculation were carried out for the wastewater from three different food processing industries namely soup, tofu, and natto. ˇ°Hi Biah Systemˇ±, which is an in situ solidification system, was used for the continuous treatment of wastewater. The parameters for the water quality were pH, five day biochemical oxygen demand (BOD5), chemical oxygen demand (COD), total suspended solids (TSS), total nitrogen (TN) and total phosphorus (TP). These parameters after the treatment became much lower values relative to those obtained before the treatment.
