SPECIAL FEATURES

Saveyor SVU membrane modules are created with advanced membrane formation technologies and

unique module structures that provide superior filtration efficiency and durability.

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 OffSaveyor 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)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:

Saveyor 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.
