This high capacity, patented separator principally relies on gravity, along with several rugged stainless steel filter elements, greatly improving product quality at a much lower cost. HydraKleen’s automatic screen rinse function keeps the filter elements clean during operation. This fully packaged unit consists of non-disposable stainless steel filter elements, pump, controller, valves and fittings, all on a mobile stand with very small footprint. HydraKleen® is optionally equipped with integral magnets, oil/water separator, and bactericidal equipment -- it may be used for reclaiming liquids and/or solids. HydraKleen® may be used as a filter or separator and is easily arranged in either configuration.

The unit comes fully assembled and is installed in less than a day. With HydraKleen®, your product quality is greatly improved at a much lower cost. In many applications using HydraKleen®, the life of process water and chemical additives has been extended from days to months -- this results in excess of 1000% cost savings over conventional process methods.
