Hydro Compliance Management, Inc.

The patented Hydro-Kleen Filtration System is a cost-effective Storm Water compliance technology for use with storm water catch

basins and drains to trap hydrocarbons, metals, sediments, and other contaminants contained in stormwater and other surface runoff.

The Hydro-Kleen Filtration System is a patented multi-media filtration design combined with pre-settling sedimentation

containment and overflow by-pass protection. Water flow enters the unit and is directed into a pre-settling sedimentation chamber

that collects heavy sediments and debris passing through the grate. Water then passes through transition inlets at the top of the

sediment chamber into the filtration chamber.
