MAK Water’s Multimedia Filtration (MMF) plants are designed to treat ground water, surface water, tertiary treated effluent, storm water or wastewater with <30 mg/L of total suspended solids. Standard filtration media includes sand media for suspended solids removal, granular activated carbon (GAC) for removal of organics, colour, odour or chlorine and DMI-65 greensand for dissolved iron and manganese. Additional filtration media, such as calcite for hardness correction and various ion exchange resins, are available on request.
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 MMF plants are available as skid mounted or containerised systems.
If you have specific requirements, contact us about our custom water filtration systems.
