Ultrafiltration – Basic


The Ultrafiltration (UF-B) plants are designed to treat surface water, tertiary treated effluent, storm water and waste water to achieve potable/process water or may be used as pre-treatment to reverse osmosis. They treat a wide range of highly variable waters with <50 NTU of turbidity and <100 mg/L of suspended solids.

The standard treatment process includes optional pre filtration (500 micron screen filter), Ultrafiltration process and automatic backwashing for membrane cleaning. Additional pre or post UF treatment steps may be added to suit feed or filtered water requirements such as iron removal, pH correction or sterilisation. The MAK UF plants are available as skid mounted units or containerised systems.

If you have specific requirements, contact us about our custom water filtration systems.
