s. 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.

A sand filter has a dirt holding capacity of 3 to 6 kg TSS / m2 of sand surface.

rs are loaded with particles, the flow direction is reversed and the flow is increased to clean the filter again. This step is called a backwash.

The anthracite traps the courser dirt particles to prevent the formation of a layer cake on top of the filter bed. The smaller particles get trapped in the sand layer. With a low fluid velocity particles will adhere to the sand with a cohesive bonding. The gravel allows the water to flow evenly to the mushroom diffusors and out of the filter medi

water flow through a bed of sand or another granular media at a low speed. When this happens, the media will pick up much of the solid matter, but the water will pass through. This usually occurs multiple times to remove enough of the toxins to make the water suitable for its particular use.
