MAK Water’s Ultrafiltration (UF) plants are designed to treat ground water, surface water, tertiary treated effluent, storm water or wastewater with turbidity <300 NTU. The standard treatment process includes pre-screening (bag filter or self-cleaning screen filter), outside-to-inside capillary ultrafiltration modules, automated air scouring and maintenance cleaning (MC) system, as well as a CIP system for periodic recovery cleaning (RC). The UF system can be configured as either: dead-end for lower turbidity applications, or cross-flow for higher turbidity applications.
Additional pre-filtration and post-filtration treatment steps may be added as required to suit feed water conditions and/or treated water quality requirements. The MAK Water UF plants are available as skid mounted or containerised systems.
If you have specific requirements, contact us about our custom water filtration systems or ask about our hire options.
