Sediment Inlet Filter Cap - BLOCKSOM

Inlet Filter Cap is a sediment trap that is used below the grate on top of the Stormwater Treatment Filtration Media.  This helps keep the Stormwater Treatment Filtration Media clean of debris and sediment, extending its working expectancy.

Wash Wastewater Filtration with ADSORBIT^® 

Initial laboratory studies show ADSORBIT^® sorbent to be very efficient in selectively adsorbing / absorbing petroleum and vegetable-derived hydrocarbons from water. This work was done using laboratory prepared and controlled test solutions. This test demonstrates ADSORBIT^®’s sorbent effectiveness by testing real-world samples. Real-world samples measure not only the ability of the filter material to remove the pollutants of interest, but also to handle water that contains floating and dissolved hydrocarbons, emulsifiers and detergents, as well as debris that might affect filter performance.

Method

We were provided a five gallon sample of effluent from a logging truck wash station. The sample was thoroughly mixed and split into two sub-samples. One sub-sample was tested to determine suspected organic and inorganic pollutants. The other sub-sample was passed through a filter system using ADSORBIT^® filter media and the filtered water was analyzed for the same pollutants.

Results of analytical chemistry are presented in the table below.

Conclusions

As can be seen in the table above, ADSORBIT^® sorbent was highly effective in removing organic pollutants and suspended solids from the sample. Especially notable is the reduction in oil and grease, diesel, motor oil and between the filtered and unfiltered samples.

The ADSORBIT^® filter fabric lined catch basin is designed to capture pollutants such as sediments, debris, petroleum hydrocarbons, PAHs and heavy-metals from stormwater runoff from industrial, commercial and residential sources.

The uniquely designed hi-flow ADSORBIT® filtration fabric material allows stormwater to flow through the fabric material for extended periods while capturing sediments, oils, oily sheen and oil-borne contaminants.  The ADSORBIT®Storm filters are designed to hold over 100-lbs of sediment and debris and can be cleaned and reused many times over.
