SAND

Turbidity removal filters are comprised of a column containing a multi-layer filtering bed of sand and quartz gravel of varying, selected grain size. The filtering media is permanent: it does not require replacement as it is regenerated with simple backwashing with water. This is carried out automatically by the head controlled by an electronic displacement timer/control.
Sand filters need to be installed at the water mains inlet and can be used to filter water for both civil and industrial use.
Available in models with varying capacities: between 25 and 500 litres.
