SuperSieve Medium prefilter.

SuperSieve Medium operates in gravity mode.

The water is piped 110 mm from the basin to the SuperSieve.

The amount of water that enters the prefilter is regulated by a float.

When the water level rises in the prefilter, the valve closes a little more through the float, thus allowing less water to flow.

A balance is thus obtained between the water that enters and the water that is pumped, which maintains a constant water level under the grid, in the prefilter.

The water that falls through the stainless steel grate is cleaned of dirt larger than 300 microns.

The water can then be directed to biological filtration by a pump that draws water kept level under the grate.

Advantages

> no need to adjust the float.

> large internal overflow.

> the water level below the filter element is fairly constant.

> almost no more problems with lack of air.

> robust quality finish.

> mounting a UV immersion possible.

Applications

As a prefilter, upstream of a multi-chamber filter.

As a prefilter, upstream of a bead filter.
