1. Brief introduction of Inside-out PS UF Membrane

Inside-out PS UF Membrane SVU membrane modules are created with advanced membrane formation technologies and unique module structures that provide superior filtration efficiency and durability. Inside-out PS Water Treatment UF (ultrafiltration) Membrane Modules SVU-1030.

2. Characteristics of Inside-out PS UF Membrane

  • Permanently Hydrophilic Membrane (proprietary technology): The operation flux of most of UF or MF membrane products is much lower than their initial flux resulting from the loss of membrane hydrophilicity by polymer reconfiguration. Saveyor SVU UF membrane ensures steady flux by fixing the hydrophilicity permanently, using a cross-link technology.
  • Lower Molecular Weight Cut Off: SVU membrane offers very fine filtration at a MWCO at 45,000 Dalton, which is the very high end of UF filtration grade in water treatment
  • Larger Diameter Capillaries: Larger diameters of the capillaries endow better anti-fouling properties to the membranes. Saveyor SVU presents only larger diameter UF capillary membranes (ID/OD=1.0/1.5mm, 1.2/1.8mm, 1.5/2.2 mm) for better performances
  • Even Arrangement of the Membranes (patented technology): A large number of membrane capillaries are evenly distributed inside a pressure vessel by a so-called sub-grouping technology so that each membrane capillary works in very similar environments
  • Soft Potting (patented technology) Drinking Water UF Membrane: The “roots” of the capillaries are the weakest portions in membrane modules, and may break during operation. These portions of membranes in Saveyor UF modules are protected by a soft layer of potting material.
  • Applications: SVU membrane modules can be used to purify well and surface water for drinking water, to filter sewage and waste water for water recycle, and to treat surface or sea water for RO and NF system.
