Deep Bed Sand Filter For Commercial Pools

POOLKING's depth sand filter has two different sand beds . Coarser less dense sand at the bottom of the filter bed, and finer , denser particles in the top layer. The downstream filtering allows very deep and effective filtration of particles and higher filtration rates. With this combination, a depth sand filter provides many advantages over a conventional sand filter.
The advantage of a fixed nozzle bottom is that filtering takes place through the entire surface . At the backwash , the reverse circulation takes place at depth which results in a very efficient backwashing. In order for a visual inspection to take place in a very simple way, the sand filter is fitted with a sight glass in clear plexiglass. Equipped with manual venting and large manhole for easy maintenance. These filters are well suited to commercial pools or spas.
