Application Profile

The Ultra-HydroKleen Filtration System is a patented multi-media filtration design combined with pre-settling sedimentation containment and overflow by-pass protection. Each unit is custom manufactured for retrofit or specification to fit your specific catch basin or drain invert size. Units are placed into drains by removing the grate/cover, inserting the unit onto the grate lip, and replacing the cover. 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. The primary media, Sorb-44, traps hydrocarbons through adsorption to a hydrophobic cellulose material. The secondary media is a special blend of activated carbon (AC-10) that removes any remaining hydrocarbons as well as a variety of other organics, and metals and other contaminants from the runoff. Water then passes through the of the bottom treatment chamber into the catch basin.

A properly maintained unit will achieve substantial reductions of contaminants from entering surface waters. Units are designed to trap contaminants contained in the "first flush" from storm events while allowing overflow protection to eliminate flooding during heavy wet weather events. To accomplish this, the filtration chamber is designed to handle 40 - 50 gpm through the media chamber, effectively handling up to ½" of rain per hour in a properly designed drain. Higher flows from high intensity wet weather events are diverted to by-pass outlets that are designed to move whatever flows the drain is designed to handle. This prevents flooding or ponding on the surface while capturing the majority of contaminant loadings from impervious surfaces. Units strategically placed downstream from "hot spots" such as gas stations, parking lots and other industrial/commercial sites containing higher contaminate loadings, give municipalities and businesses an effective tool for reducing pollutants.

Ultra-HydroKleen Filtration Systems are cost-effective and can be installed at a fraction of the cost of a conventional oil-water separator and other BMP's. A typical unit will cost under $2,000. Moreover, this system does not require expensive installation as it can be retrofitted into existing storm drains as well as specified into new or re-development projects.

Ultra-HydroKleen Filtration System is also an effective pre-treatment device when used in conjunction with groundwater infiltration systems, detention facilities, water retention systems and oil/grit separators. It can also be utilized as a post-treatment device in wet pond risers. The application of a Ultra-HydroKleen Filtration System for compact project sites is ideal for eliminating the need to set aside land for detention basins or for using traditional, expensive oil-water separators, where land use is minimal such as in urban settings.

As with any system, the unit must be maintained on a regular schedule to prevent saturation of the filter media by contaminants and blockage from sedimentation and debris buildup. Maintenance is simple and can be accomplished in minutes by merely vacuuming sediment loadings from the sedimentation chamber and replacing the filters. With surface access there is no confined space entry. There is also no pump and haul issues as there is no free product or liquid hydrocarbons to dispose of. It is recommended that filters be changed every 4 to 6 months depending on the application. Disposal of the spent media in a typical application may be accomplished through placement into lined landfills, as the filter media is non-leaching. Always ensure compliance with all local regulations prior to disposal.
