Multimedia Filtration
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.
Extra 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.

Applications
Real-world examples
MAK Water was engaged to deliver the process water and potable water treatment plants for the Cobre Project, one of the larger copper mine developments in Central America. As this was a Greenfield project and the exact feed water quality was uncertain, MAK Water proposed a robust process incorporating: • Chemical flocculation to improve efficiency of solids separation • Lamella clarification as pre-treatment to account for spikes in suspended solids, and • Media filtration in order to achieve the final quality of process and potable water for the site. MAK Water was selected thanks to its innovative modular containerised design, extensive experience in delivering high quality packaged water treatment plants for remote mining projects, and its ability to customise the solution to meet the project requirements.

Potable Water for Meat Processing Facility
A leading Western Australian meat processor and exporter required additional treatment of the dam water it was using in its factory as wash down water to improve the standard of its abattoir and maintain international accreditation. MAK Water worked closely with the client to review water data, site requirements, and provide a number of possible equipment solutions. The customer selected a custom filtration and sterilisation plant, specifically designed by MAK Water to meet its requirements and provide a reliable long-term solution with the appropriate degree of filtration and UV log reduction.

Potable Water Treatment for Primary School Campus
When the Swan Christian College Association was planning to build a new secondary campus in the Perth Hills they identified that the new development would be without access to water and wastewater services for several years. They required an alternative medium-term source of potable water and engaged a local hydraulic consultant to manage the process. MAK Water was engaged to design and manufacture a system to treat the available bore water for potable use at the school and maintain compliance with the Australian Drinking Water Guidelines (ADWG). MAK Water also consulted with local authorities on behalf of the school to develop and gain approval for the required Drinking Water Quality Management Plan
