Consolidated Water Conditioning has developed a range of compact, easy-to-use ultrafiltration (UF) systems for the pre-treatment of water supplies high in suspended solids and turbidity. Our UF systems are ideal for use at game lodges, farms and other installations where river or dam water is used to provide water for drinking, laundry and general hospitality uses.
Ultrafiltration is a membrane filtration process similar to Reverse Osmosis, using hydrostatic pressure to force water through a semi-permeable membrane. The pore size of the ultrafiltration membrane is usually 103 - 106 Daltons. Common applications for ultrafiltration systems are food & beverage processing, pharmaceutical use, municipal , borehole and surface water treatment.
In filter mode, feed water flows inside the ultrafiltration membrane fibre, in either a cross-flow or dead-end filtration configuration, depending on the feed water quality. Filtrate is collected into the central core tube and passes out to process.
In backwash mode, filtrate backwash flows from the central core tube to inside the fibre tubes and out to drain. In most systems, the backwashing cycle is controlled by a timer or differential pressure switch.
In applications where complex contaminants are present in the feed water, or additional treatment is required, chemicals may be used during the backwashing process. Usually, sodium hypochlorite and hydrogen peroxide are used to help flush the membrane surface of impurities.
