Diefenbach iONIC filter presses are built using high-grade stainless steel and other protective coatings where necessary. This allows them to withstand even the most acidic and corrosive sludges and makes them ideal for processing a variety of highly acidic slurries, such as in lead and lithium battery recycling applications.
Like all Diefenbach filter presses, the iONIC filter press features recessed or membrane plates that when pressed together form chambers. The acidic sludge is pumped into the filter press from both ends, filling the chambers. The solids in the slurry are trapped inside the chamber on cloths attached to the filter plates. The liquid in the slurry passes through these cloths and exits the press. At the end of the filtration cycle, the plates open, discharging the solid cakes.
