SVU membrane modules are created with advanced membrane formation technologies and
unique module structures that provide superior filtration efficiency and durability.
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.
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 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
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
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.
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.
