Washing Wastewater

Coal washing wastewater is the end of the wet coal mine coal washing process industrial water , which contains a lot of slime and silt , causing serious pollution to the environment of the mine near this study, coagulation treatment of coal washing wastewater to determine the best flocculants and optimum operating parameters : agitation intensity 90r/min, polyaluminum chloride (30mg / l) dosage of 10ml the polyacrylamide dosage 3ml , pH = 7-11 . The treated effluent can be reused , either to protect the environment , but also save water resources .
