Environmental Remediation

Removing Contaminants from Groundwater, Soil, and Surface Water

Hydrosil has experience in environmental remediation projects of over 20 years. This experience predominantly falls in the pump and treat method of removing contaminants. Pump and treat (P&T) systems involve pumping contaminated water through a series of vessels that are filled with filtration media (i.e. activated carbon, organoclays). Hydrosil works with the customer to ensure that the series of vessels have the correct media to remove the contaminants of concern with the appropriate contact time. Hydrosil International manufactures bulk media to remove dissolved organics, dissolved minerals, oils and greases, and specific organic compounds.

HS-100

Hydrosil’s HS-100 is designed to remove ammonia in water. This product is commonly used in stormwater treatment and process water reuse.

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.

HS-250

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.

HS-250-ACR

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.

HS-270

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-600

The HS-600 is used in gas phase applications. The product targets chlorinated solvents, acid gases, and various sulfur compounds. The product is commonly used in soil vapor extraction, and deep bed scrubbers.

HS-AC Liquid Phase

The HS-AC is granular activated carbon (GAC) produced from coconut shells. The product targets inorganic and organic compounds in a wide range of applications.

HS-AC Vapor Phase

The HS-AC is granular activated carbon (GAC) produced from coconut shells. The product targets inorganic and organic compounds in a wide range of applications. The product is commonly used in soil vapor extraction, and deep bed scrubbers.

HS-ACC Liquid Phase

The HS-ACC is granular activated carbon (GAC) produced from coal. The product targets inorganic and organic compounds in a wide range of applications. The HS-ACC removes PFAS and PFOA compounds.

HS-AS

Hydrosil’s HS-AS is designed for arsenic removal for water treatment. The HS-AS is commonly used in pump and treat systems and polishing water in industrial settings.

HS-F

Hydrosil’s HS-F is designed for fluoride removal for water treatment. This activated alumina is an adsorbent of metals as well as fluoride.

HS-MT

The HS-MT is extremely effective at removing dissolved metals. Common metals found in water include nickel, cadmium, zinc, chromium, and thallium. This product is typically used in groundwater and surface water treatment.

HS-PF

The HS-PF is designed to remove per- and polyfluoroalkyl substances (PFAS). The media is selective for removing PFAS (PFOA, PFOS, FTCA, FTSA, FTOH). The media is not used for potable drinking water applications, but typically for groundwater and landfill treatment.

HS-200+ Sediment

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.

Common Treatment System Design:

Free Standing Mode: Used on its own, Hydrosil’s media can be loaded in drums or large vessels for use as an efficient bed filtration medium. Other applications include tank cleaning, oil spill mitigation, stormwater run-off, pond clean-up, excavation and dewatering, manufacturing/chemical processes, and lining/capping projects.

Pre-Treatment Mode: Media is used upstream to enhance the performance and extend the useful life of other filtration processes and media such as reverse osmosis (RO), granular activated carbon, activated alumina, and resins. Fouling of RO systems is not uncommon due to the presence of silica, oil, and heavy metals.

Post-Treatment Mode: Media is utilized downstream of an oil-water separator or coalesce filter, has the ability to act as an effective cleaning and polishing agent.
