Description:

Completed in 1992, the depot installed 15 out of 35 in-tank mechanical filters. The equipment pumps, filters, agitates and treats (the flocking filters purchased from Custom Masters Inc. Longwood, FL). The filters are cleanable, at the shop level, for up to 200 solution changes and are designed to remove organics, heavy metals and particulates from plating solutions. The filters contribute very little to the volume of hazardous waste and extend the life of the plating bath five fold.

Environmental Benefits:

The filters have reduce the generation of hazardous waste by 45 pounds of sludge per year. Employee safety and spill prevention are greatly improved by eliminating decanting and desludging operations.
