The CONTIFLOW® Sandfilter is an upflow filter with a continously cleaned filter bed, making shutdowns for backwashing of the filter bed unnecessary. Also the reservoirs for wash water and sludge liquor can be spared.
Feed is introduced at the top of the filter and flows downward through an opening between the feed pipe and airlift housing. The feed is introduced into the bed through a series of feed radials which are open at the bottom. As the influent flows upward through the moving sand bed, the solids are removed. The filtrate exits at the top of the filter.
Simultaneously, the sand bed, along with the accumulated solids, is drawn downward into the airlift pipe, which is located in the centre of the filter. The sand and the solids are transported through the airlift into the washer / separator with central reject compartment. As the sand falls through the washer, which consists of several concentric stages, a small amount of filtered water passes upward, washing away the dirt, while allowing the heavier, coarser sand to fall through to the bed.By setting the reject weir at a lower level than the filtrate weir, a steady stream of wash water is assured. The continuous reject exits near the top of the filter. By variation of the weir height, optimal adjustment of the wash water volume is possible.
The method allows continuous filtration of the water and wastewater without shutdowns for backwash cycles.
