The Filter Innovations “Pump & Treat” Oil Adsorption System is the simplest, most efficient and most versatile method for removing oil and grease in wastewater streams.

The Pump & Treat System utilizes a new filter media designed to adsorb high molecular weight, low solubility organic compounds (e.g. oil, grease, pentachlorphenols, PCBs, etc.) This media is derived from chemically modified smectite clays and capable of efficiently breaking down and removing mechanically emulsified organic compounds.

The organics are adsorbed due to a partitioning phenomenon: they are preferentially partitioned out of the aqueous phase and into the organic phase between the clay platelets. Once they are adsorbed, the organics are tightly bound to the media.

As more organics are adsorbed, the clay platelets spread further apart, thus creating additional space for adsorption. TM-Media has a tremendous adsorption capacity that is 6-10 times greater than that of activated carbon. In general, the removal rate for oil and grease is approximately 90-95%.

The unique characteristics of the media can also be harnessed to mechanically stop the flow of contaminated liquids, thereby eliminating the possibility of environmental contamination in the case of a large spill. TM-Media also offers increased bed life, which results in reduced maintenance requirements.
