The suspended solid particles in electrolytic solution could be filtered in the Purification filter by the adsorptive filtration technology, to be reduced to a remarkable low concentration level as 3 - 5 ppm. The filter is operated automatically, fully sealed without leaking risk, which means very low cost for operation and maintenance, and it needs only to replace the filter bag and edgestrips when the filtering performance cannot meet the demands. Filter area is normally between 180M2 and 700M2, which also can be designed according to customer demands;
