The silicon wafer grinding wastewater contains single crystal silicon powder with a very high SS concentration, and the powder has a poor sedimentation performance. At present, the main method of dosing and sedimentation is adopted in China, which not only increases the amount of sediment, but also the sedimentation water does not meet the standard, and the water cannot be reused because of the additional chemicals added. 

This equipment is the standard equipment of Top Water Ceramic Membrane. Each set of equipment has a daily processing capacity of 200T, and realizes automatic operation. The effluent quality meets the reuse standard, and it can recover powdered silicon to realize the effective recycling of resources.
