HanPES PH-grade Highly Asymmetric Polyethersulfone Membrane
HanPES PH-grade membrane features a highly asymmetric structure: the larger pores at the inlet side capture bigger particles, while the smaller pore dense layer near the outlet side retains fine particles. The outlet surface layer protects the innermost dense layer, preventing scratches or damage.
The specially designed thick membrane structure provides high flow rate with low pressure drop, while achieving high dirt-holding capacity and extended service life. It is suitable for high particle load filtration or as a pre-filtration layer.
