Continuous Vacuum Filtration Enhances Zinc Oxide Process
#0183;#32;The Madison facility was using a plateandframe filter press to filter a zinc oxide slurry made from a mix of various zinc feedstocks. The solids are mixed with water to form a slurry of 20% solids and then filtered. The cake is bagged in 2,000lb totes, moved to another area of the plant and reslurried in sulfuric acid for further processing.
