UF Membrane

HiSep UF Module

Product Material Composition

HiSep ultrafiltration membrane is manufactured with polysulfone which has high thermal resistance, high mechanical strenght. Especially, the ultrafiltration membrane with polyacrylonitrile which has hydrophilicity and anti-fouling property shows good performance in the field of waste water treatment.

HiSep UF can be applied in various water treatment by choosing proper membrane material.

Low Cost

By developing ultrafiltration membrane with polyacrylonitrile, we can provide this hollow fiber membrane for water treatment at a low cost and guarantee optimal conditions for your processes.

High Efficiency

Hollow fiber type ultrafiltation membrane has good permeability and shows sharp MWCO. We provide perfect method for treating industrial wastewater.

Various Applications

Hollow fiber type ultrafiltration can be applied in various water treatment such as electro-deposition paint process, concentration of emulsion oil compounds and the other wastewater treatments. It also can be used in food and pharmaceutical processes.
Most of all, one of the advantages is that in running a process the optimal conditionscan be controlled properly by feeding back the results obtained from test process.

HiSep Hollow Fiber type UF Module

The Mode of Filtration

Wastewater is pumped through the hollow fiber membrane, Water, dissolved solids and low molecular weight materials pass through the membrane for discharge, reuse of further treatment. Dissolved macromolecules, suspended solids, colloids and other sub-micron materials is contained inside hollow fiber for recycling or concentration.
Wastewater is pumped across the membrane surface at high flow rates, this parallel flow eliminates the cake build-up on the filter surfaces of conventional filters such as catridge and bag filters. Material passes unimpeded through the membrane, therefore eliminating accumulation of material within the hollow fiber.

Structure of Hollow Fiber Type UF

HiSep hollow fiber membrane is composed of dense skin layers on the inner and outer surfaces and micro porous support layer in the middle of the membrane.
Separation properites are controlled by the skin layers which are supported by the micropore support layers under the surfaces.
Permeate flux speed become high by diminishing the resistance to permeate through large voids located in the inner part of the membrane.

Hollow Fiber Membrane Module

HiSep has large effective membrane area per unit volume. So it shows high performance in permeability. The membrane area per unit volume. So it shows high performance in permeability. The membrane system can be made to be compact. Especially, back-flushing through permeate side is available in hollow fiber membrane module, which is good for residue recovery and maintenance of reliability.

Specifications & Performance

Spiral Wound type UF Module

Spiral Wound Module

A variation of the basic plate-and-frame concept is spiral wound module, which is widely used today in reverse osmosis, ultrafiltration, and microfitration. The basign is illustrated above. The feed flow channel spacer, the membrane, and the porous membrane support are rolled up and inserted into an outer tubular pressure vessel. The filtrate is collected in a tube in the center of roll.
