What is Organoclay
What is Organoclay?
Organoclay, is a sorbent media which is designed to remove organic components. The media is a naturally occurring mineral (commonly zeolite or bentonite clay) which is chemically alternated to create a unique surface on the mineral.
Organoclay naturally has a high cation exchange capacity (CEC). The media is then manipulated with additives such as cationic surfactants and added to the mineral to modify the surface. By modifying the surface, we create a strong affinity with organic compounds, meaning the media is organophilic. The surface of the media forms a surfactant bilayer which attracts ionic species. Ionic species are components that in solution are grouped as either anionic (anions) or cationic (cations). Anions have a negative charge and cations have a positive charge.
Organoclays are used in pump and treat remediation systems, sediment capping, industrial water treatment (petrochemical, pulp & paper, manufacturing).
Benefits when Using Organoclays
Verstile installation — Load the media in standalone units, post-treatment, or pre-treatment units. To learn more about these systems on our Water Filtration Systems Page.
Cost Savings — Organoclay is an economical alternative to other treatment technologies such as resins or GAC.
Increase Efficiency — Organoclays will decrease the loading on other treatment systems and increase the life of capital equipment.
Storage — Organoclays have a long shelf life and require dry ambient environments.
Handling — Organoclays are safe and easy to use.
Hydrosil’s Organoclay Series
Below is a list of the products in Hydrosil’s Organoclay Series and brief description of the most common pollutants that are targeted.
HS-200
The HS-200 targets oils/grease, hydrocarbons, cations, non-aqueous phase liquids, and heavy metals.
This product is commonly used in dewatering sites, groundwater remediation, condensate treatment systems, process water reuse, pre and post industrial water treatment.
The HS-250 is a 50/50 blend of HS-200 and anthracite coal targeting heavy metals, oils, petrochemical compounds. This product is commonly used in dewatering sites, groundwater remediation, and stormwater.
HS-250-AC
The HS-250-AC targets a wide range of organics and inorganic compounds. Commonly used on BTEX, heavy metals, oils, semi-VOCs. The HS-250-AC is a 50/50 blend of HS-AC and HS-200.
The HS-250-ACR is a 50/50 blend of HS-200 and HS-ACR targeting heavy metals, oils, petrochemical compounds. This product is commonly used in dewatering sites, groundwater remediation, and stormwater.
The HS-250 is a 30/70 blend of HS-200 and anthracite coal targeting heavy metals, oils, petrochemical compounds. This product is commonly used in dewatering sites, groundwater remediation, and stormwater.
HS-275
The HS-275 is modified organoclay that targets low molecular weight hydrocarbons. This product is typically used in groundwater treatment for refineries.
HS-300
The HS-300 targets anionic compounds such as phosphates, nitrates, sulfates, cyanides. This product is commonly used in dewatering sites, groundwater remediation, and stormwater.
HS-350-AC
The HS-350-AC targets a wide range of organics and inorganic compounds. Commonly used on anionic compounds such as phosphates, nitrates, sulfates and large organic compounds. The HS-350-AC is a 50/50 blend of HS-AC and HS-300.
Hydrosil offers a variety of other products that aren’t in the Organoclay Series.
