How is filtration managed?
During processing, metal is dissolved from the part and is turned into suspended hydroxide particles. These particles are collected by an efficient cartridge filtration system located on the suction end of the filter pump, located in the electrolyte conditioning tank behind the main process tank. As the filter fills with hydroxides, the sludge will accumulate to approximately ½” thick. This is your indication that it is time to change the filter elements. Although considered low level, the hydroxide sludge from deburring aluminum, stainless steel or iron parts is still considered toxic waste by definition. In the worst case, such material is carted away as an industrial waste by a licensed hazardous waste disposal agency. A high volume operation may produce one drum of filters annually.
