Specialty Filter Media TM-Media

Description Of A New Technology

The heart of this technology is a new filter media designed to absorb high molecular weight, low solubility organic compounds (ie. Oil, grease, pentachlorophenols, PCB’S). This media also efficiently breaks and removes mechanically emulsified organic. It is derived from a chemical modification of smectite clays.

The media absorbs organic through a partitioning phenomenon. The organic will preferentially partition out of the aqueous phase and into the organic phase, between clay platelets. Once they are absorbed, the organic are tightly bound.

As more organic are absorbed, the clay platelets will spread further and further apart, creating space to absorb more organic (see figure 1). The swelling is strictly a function of the absorption of organic molecules, not water. For this reason, TM-Media has a tremendous absorptive capacity, 6-10 times greater than that of activated carbon. In general, you can expect a 90 - 95 % removal rate for oil and grease.

The unique characteristics of the media can also be used to mechanically stop the flow of contaminated liquid, thus eliminating the possibility of environmental contamination in the case of a large spill.

Highlights Of TM-Products

Economical

TM-MEDIA has a greater capacity for the absorption of higher molecular weight hydrocarbons (up to 60% of its weight), which means longer bed life (6 to 10 times longer than carbon).

Fewer pounds required in typical bed means:

1. Lower media costs
2. Reduced bed height
3. Lower equipment costs
4. Minimization of amount of waste to dispose of
Longer Bedlife means less Manpower required for bed changes.

Dependable

TM-MEDIA can accommodate increases in contaminant concentration levels caused by plant upsets. TM-MEDIA is thermally stable up to 300 degrees celsius.

Easy To Use

Versatile - can be used in columns in both the downflow and upflow mode no bed conditioning required to increase absorption capabilities. No carcinogenic dust problems associated when filing vessels.

Disposal

Filter Innovations has eliminated your disposal problem by arranging a cradle to grave life cycle this includes the acquisition of the media, the utilization of the product and the final disposition of the spent media. The final portion of this cycle is achievable because of the high BTU value of the spent media. As a result, it may be incinerated as a fuel in fuel blending programs, which are supplying cement kiln operations.

The spent media could also be disposed of at a landfill. The material is non-hazardous because it will not leach any hazardous constituents when subjected to the TCLP (Toxicity Characteristic Leaching Procedure) test for determining if a waste meets the criteria for a hazardous waste classification.

In summary, we feel that the excellent absorption capabilities of the TM-products to remove large molecular weight organic can effectively minimize the amount of contaminants discharged, as well as meet or exceed the new discharge limits set by government agencies.

Potential Applications

The TM-Media may be used in the following applications in the stand alone mode, such as in the treatment of steam condensate; in the pretreatment mode, for protection of other treatment processes such as activated carbon, reverse osmosis and desalination; and in the post-treatment mode, for polishing effluent from DAF units, API oily water separators, coalescers, ultrafiltration units, air strippers, and System AC units.
