The multimedia mechanical filters are widely used in agricultural irrigation.chemical engineering, petroleum, metallurgy, mining, electric power, petrochemical,metallurgical electroplating, papermaking and textile, pharmaceutical dialysis, foodand beverage, domestic drinking water, factory and enterprise water, swimmingpools, etc. It can satisfy the liquid filtration demand of various industries.

The success of multimedia filters depends on the optimised arrangement of variousparticulate removal mechanisms working in parallel. Good media selection andlayering is important in maximising treatment efficiency.

At the bottom, sand functions as a support and mechanical filtration barriertrapping the coarsest solids. Anthracite also traps finer particles by adsorption andstraining.

Anthracite is important as the layer above GAC is often used in filters targetingchlorine or organic removal for chemical adsorption. An alternative may bemanganese greensand or other oxides for metals treatment applications.

In selecting this intermediate medium, its density should approximate the densityof the upper anthracite, so that mixing will not occur during backwashing. Mediauniformity and grain size ratios between are also important in effectivebackwashing.
