The system maintains a consistent bath quality and is designed for high temperature, high caustic environments typically found in aqueous cleaning operations. Contaminated cleaner is pumped from the customer's cleaning bath to the system. The feed valve, which is controlled by a level sensor, maintains a proper level in the process compartment where free oils and sludge are removed. Fluid from the middle of the settling compartment flow into a process compartment where contaminants are concentrated. Process fluid is pumped at high circulation rates through the channels of the ceramic membrane where contaminants are separated from the cleaner. Purified cleaner (filtrate) flows radially through the ceramic filter, collects in the filter housing, and flows back to the customer's cleaning bath.
A high pressure, automatic backpulse device periodically dislodges solids and oil from the membrane surface to minimize fouling and maintain a high filtration rate throughout the operation of the system.
