Organoclay applications include groundwater pump and treat, sediment dewatering, as an amendment in an in-situ solidification/stabilization application, in a permeable reactive barrier, and as part of a sediment cap. Compared to activated carbon, organoclay has a high adsorption capacity of oil and grease and because of this organoclay is often used as a pretreatment media before activated carbon to not blind the carbon and extend its life. Organoclay also has a higher capacity for adsorbing less soluble, higher molecular weight organics. Various organoclays are available depending on the application, some of which are provided below.
A proprietary granular filtration media that reliably adsorbs oils and similar organics from water. It is a mixture of 30% active ORGANOCLAY and 70% anthracite filter media, which allows for maximum utilization of the large sorption capacity of ORGANOCLAY without excessive pressure build-up in the column. Applications include: Groundwater Pump-and-Treat and Sediment Dewatering Treatment.
In addition to adsorbing non-aqueous phase liquids (NAPL) and dissolved low-solubility organics, specially-formulated, sulfur-impregnated ORGANOCLAY MRM sequesters mercury (Hg0, Hg+1 and Hg+2) and arsenic (As+5) from water. Applications include:
Our finest-grain media, ORGANOCLAY SS-199 features medium adsorption of oils, greases, and other NAPL and helps stabilize organics for increased solidification of treated soils and sediment. ORGANOCLAY SS-199 is for use in soil or sediment solidification/stabilization or as an additive to Portland Cement.Applications:
Our second finest grain media, PM-199 features high adsorption capacity of oils, greases, and other NAPL and can be used on its own or in series with activated carbon. When used as a filtration media prior to an activated carbon vessel, PM-199 extends the life and of activated carbon by removing larger molecular organics that can cause fouling. Applications include:
Our second coarsest grain media, ORGANOCLAY PM-200's particle size aids in settling through the water column when placing a bulk active in-situ sediment cap. ORGANOCLAY PM-200 is also your best match for intermixing with coarse inert soil for use of a Permeable Reactive Barrier (PRB) or for Bulk Sediment Capping.
Our coarsest grain media, ORGANOCLAY BB is a larger and denser version of ORGANOCLAY PM-200 to aid in settling through the water column. When used for sediment capping, ORGANOCLAY BB can be placed hydraulically or mechanically.
