Abstract
A filtration system and assembly for liquid mixture applications is disclosed. The system comprise of a pump, filter, venturi, and by-pass that incorporates a flow control valve. The flow control valve controls the flow and pressure of the retentate thereby determining the rate that permeate is produced. All components are configured in a closed loop configuration. System stability and high permeate flow result from the optimum selection of system components. The disclosed system has a simpler control system and is easier to operate than similar functioning systems in use. Applications exist in microfiltration, ultrafiltration, and nanofiltration.
