Tap water filtration system.
In a plate-and-frame filter press, the filter cake is washed by pumping water through the filter after the cake has been deposited on the filter cloth.1
Once the filtration process is complete and the cake has formed, the wash water is introduced to displace the remaining liquid or impurities within the solid mass. Following this washing stage, the plates are separated, and the filter cake is removed manually.12
