Organoclay media | Organic Adsorption Media
Organoclay bentonite is produced by modifying natural bentonite (primarily composed of montmorillonite) through organiclay modification. Montmorillonite has a layered silicate structure, with interlayer exchangeable cations (such as Na⁺ and Ca²⁺). Through ion exchange technology, long-chain organic ammonium salts (such as octadecyl trimethyl ammonium chloride) are inserted into the structure, forming hydrophobic, oil-loving organic composites.
Organobentonite can treat crude oil, floating oil, dispersed oil, and emulsified oil in oilfield wastewater, as well as heavy metals such as lead, cadmium, and mercury.
As a high-quality adsorbent, organo clay bentonite can also treat organic compounds (phenols, benzene compounds, polycyclic aromatic hydrocarbons) and Na⁺, Cl⁻, etc., in high-salinity environments. When using organic clay bentonite adsorption columns to treat oily wastewater in oilfields, the removal rate of oil content reaches 98%.
The adsorption capacity for emulsified oil (particle size <10 μm) can reach 200–300 mg/g, significantly outperforming traditional adsorbent materials.
In terms of heavy metal removal, when treating wastewater containing Pb²⁺ (concentration 10 mg/L), the concentration is reduced to below 0.1 mg/L after adsorption. The adsorption capacity for Hg²⁺ can reach 150 mg/g, far exceeding that of unmodified bentonite (30 mg/g).
When treating wastewater containing benzene (COD 800 mg/L), the removal rate reaches 87.5%.
It is also highly environmentally friendly: a natural mineral-based material with no secondary pollution. Its adsorption capacity can be restored through acid washing or pyrolysis, enabling cost-effective recycling and regeneration. Therefore, the use of organic bentonite for wastewater treatment in oilfields is highly economical.

ORGANOCLAY CP-200
—-ORGANIC ADSORPTION MEDIA
Organoclay media CP-200 is a proprietary granular media that is highly effective in
adsorbing organic compounds, particularly non-aqueous phase liquids (NAPLs),
dissolved polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls
(PCBs).
APPLICATIONS:
Organoclay media CP-200 is specially formulated for use in the following applications:
Organophilic Filtration Media: as flow through medla for treating groundwater and
leachate.
Organoclay media Bulk Capping: provides subaqueous chemical isolation of
contaminated sediment NAPL seeps in waterways.
Permeable reactive barrier.
Solidification/Stabilization additive: improves hydraulic and leachability performance
of pozzolanic mixes by adsorbing NAPL and dissolved low solubility organics.
ADVANTAGES:
As filtration media used in series prior to activated carbon vessel, it extends life and
adsorbency of activated carbon by removal of larger molecular organics that can cause
fouling.
Operates in stand-alone mode for treatment of oil contaminated waters or steam
condensates.
