1. PVDF/PS/PES hollow fiber UF membrane 2. stable filtration effect 3. Stronger tolerance in chemicals. ACE-225ACE-225 adopt 3 side open design, cell density filling pattern, silk film distribution good, ACE series film has the largest area, the maximum water production, pipe connections easier. Membrane column head using flexible materials. Can be filled with modified PS, PES, PVDF membrane ...
