The Water Decontaminator is the best available technology for treating stormwater at the source.
Dirty water entering through the catch basin grate is funneled into the filter housing. The water then flows through a proprietary mixture of wood pulp media, polypropylene and activated carbon. This mixture has been shown to remove the common pollutants entering the stormwater system. These pollutants include total suspended solids (TSS), oil, grease, and heavy metals. The treated water then flows out of the Water Decontaminator into the catch basin.
The filter cartridge is designed so that first flush storm events pass through a denser portion of the filter. This is because first flush events usually contain a much larger concentration of contaminants. Maximum filter efficiency is achieved for the standard WD 10x18A filter at 20 gpm. Flow rates above 20 gpm will overflow the filter housing to prevent flooding, and will not reduce the designed flow rate of the catch basin.
Larger units with multiple filter cartridges can accommodate any load.
Filters can be fitted with an optional collection tube for effluent stormwater sampling.
Typical Filter Specifications:
- Total of 6 Lbs. of filter media.
- 4.5 Lbs. absorbent.
- 1.5 Lbs. of activated carbon.
- Filter cartridge contains 1,200 cubic inches of filter media.
The standard model of the Water Decontaminator is designed to fit most standard catch basins (Minimum diameter: 16", Minimum depth: 36"). Custom filters can be built to fit any needs.
