Ultrafiltration Membrane
Ultrafiltration (UF) is a type of membrane filtration in
which hydrostatic pressure difference across the semipermeable porous membrane separates
physical impurities/solutes from the raw solution. CDMS UF membrane is a Hollow fiber of
specialty hydrophilic material capable of separating substances at a very low pressure
drops across the membrane thereby making them a low energy consumption membranes.
CDMS UF is used to remove essentially all colloidal particles (0.02 to 1.0 microns) from
water and some of the largest dissolved contaminants. The pore size in a UF membrane is
mainly responsible for determining the type and size of contaminants removed.
Applications :
- All paint industries such as pigment manufacturer, coating industry and
paint manufacturing.
- In recent years, ultrafiltration has been widely used in the fields of
water treatment, such as drinking water purification, wastewater treatment,
industrial wastewater treatment and water reuse.
- Membranes are employed for the removal of bacteria and other
microorganisms, particulate material, and any material, which can impart
color, tastes, and odors to the water and react with disinfectants to form
disinfection by-products (DBP) above 0.02 Micron particle size.
- Ultrafiltration plays major role in dairy industries. It is used for milk
concentration by separating excess water from milk without losing its
constituents.
- UF membranes are used as a pre-treatment to RO membranes
Advantages :
- No need for chemicals (coagulants, flocculates, disinfectants, pH adjustment)
- Can work on Auto-Mode.
- Automatic cleaning of filters
- Low on maintenance
