摘要：The removal of turbidity in wastewater with coagulants based on paper sludge ash was investigated. Until now, polyaluminium chloride (PAC) and polymer coagulant have been used for the reduction of turbidity in wastewater. However, there are a variety of wastewaters which cannot be treated with these agents, including effluent from the paint industry. Recently, a new coagulant (Ago clean P) has been developed which is made of paper sludge ash. In the present study, the coagulant made of paper sludge ash was applied to the removal of turbidity in paint industry wastewater. Treatment using Ago clean P coagulant was found to be very effective for paint industry wastewater, while the combination of Ago clean P coagulant with the traditional PAC and polymer coagulant treatment was found to contribute to reducing the amount of Ago clean P required for coagulation.
