MEMBRANE FILTRATION EQUIPMENT FOR USING PULSE OF CROSS-FLOW WATER

摘要

PURPOSE: A cross-flow-based membrane filter based on pulses is provided to save costs required for power by forming cross-flow based on pulses instead of flow rate-based cross-flow in case of the introduction of highly turbid raw water. CONSTITUTION: A cross-flow-based membrane filter based on pulses includes a hollow fiber membrane bundle(50), a filtering body(100), a pulse pump(110), a relief valve(120), and a controlling part(150). The hollow fiber membrane bundle purifies raw water. The filtering body is shaped into a pipe form in order to embed the hollow fiber membrane bundle. The pulse pump is in connection with the lower part of the filtering body. The pulse pump generates pulse pressures. The relief valve is in connection with the upper part of the filtering body and opens according to set pressures. The controlling part controls the pulse pump and the relief valve.
