Sediment Capping, Stabilization, and PRB

HS-200 Liquid Phase, Pure Organoclay

Hydrosil’s HS-200+ is active capping technology for isolating contaminates (i.e., heavy metals, polyaromatic hydrocarbons (PAH), and polychlorinated biphenyl (PCBs)) from damaging surrounding aquatic environments such as lakes, rivers, groundwater. The HS-200+ is commonly used in sediment caps for isolating oils, greases, organic and inorganic compounds.

By altering the chemistry of the zeolite based organoclay, Hydrosil enhances the adsorption characteristics of several organic and heavy metal compounds: benzene, phenol, ethylbenzene, and naphthalene.
The HS-200+ is organophilic clay which has an oil adsorption capacity that minimally holds 70% of its’ own weight in oils. The material is also effective at removing polycyclic aromatic hydrocarbons (PAH).

The HS-200+ is installed for in-situ stabilization and permeable reactive barrier (PRB) treatment in groundwater applications.
