Soil Remediation Technology
Adventus Daramend
 DARAMEND® is an advanced biological treatment technology for soil, sediment, and solid wastes contaminated with recalcitrant organic compounds. DARAMEND® technology has been successfully applied to more than 7,000,000 metric tons of soil, sediment, and other wastes contaminated with polycyclic aromatic hydrocarbons (PAHs), PCP, phthalates, chlorinated herbicides and pesticides, organic explosive compounds and wood preservatives at a variety of industrial and military sites in the United States, Canada, Australia and Europe.
Adventus Daramend-M
DARAMEND®-M is a variation of the Daramend product for use on metal-impacted soils. This technology is proven to be capable of reducing the amount of metals that can leach from metal-impacted soil, in particular the amount of leachable metal in samples analyzed using the Toxicity Characteristic Leaching Procedure (TCLP).
Adventus Aerobic Daramend
Aerobic Daramend is a variation of the Daramend product suitable for Chlorobenzenes, 2,4-D, phthalates, PAHs, Creosote, ammonia and nitrates. DARAMEND® is an advanced biological treatment technology for soil, sediment, and solid wastes contaminated with recalcitrant organic compounds. DARAMEND® technology has been successfully applied to more than 7,000,000 metric tons of soil, sediment, and other wastes contaminated with polycyclic aromatic hydrocarbons (PAHs), PCP, phthalates, chlorinated herbicides and pesticides, organic explosive compounds and wood preservatives at a variety of industrial and military sites in the United States, Canada, Australia and Europe.
Adventus EHC Fine Iron
EHC® is a controlled-release, integrated carbon and zero valent iron (ZVI) source that yields redox potential (Eh) in the -500 to -650 mV range. This Eh is significantly lower than that achieved when using either organic materials (lactate, molasses, and sugars) or reduced metal alone. Eh potentials in this range facilitate the timely and effective removal of normally recalcitrant chlorinated organics (e.g., CT, PCE) and other persistent compounds (e.g., perchlorate) without the formation of potentially problematic intermediates, such as DCE/VC from the anaerobic degradation of PCE/TCE or CF/DCM from the anaerobic degradation of CT.
Adventus EHC Super Fine Iron
EHC® is a controlled-release, integrated carbon and zero valent iron (ZVI) source that yields redox potential (Eh) in the -500 to -650 mV range. This Eh is significantly lower than that achieved when using either organic materials (lactate, molasses, and sugars) or reduced metal alone. Eh potentials in this range facilitate the timely and effective removal of normally recalcitrant chlorinated organics (e.g., CT, PCE) and other persistent compounds (e.g., perchlorate) without the formation of potentially problematic intermediates, such as DCE/VC from the anaerobic degradation of PCE/TCE or CF/DCM from the anaerobic degradation of CT.
Adventus EHC-F Sol Carb Super Fine Iron
EHC-F is a variant of the EHC product which contains a soluble form of carbon and superfine iron particles. EHC® is a controlled-release, integrated carbon and zero valent iron (ZVI) source that yields redox potential (Eh) in the -500 to -650 mV range. This Eh is significantly lower than that achieved when using either organic materials (lactate, molasses, and sugars) or reduced metal alone. Eh potentials in this range facilitate the timely and effective removal of normally recalcitrant chlorinated organics (e.g., CT, PCE) and other persistent compounds (e.g., perchlorate) without the formation of potentially problematic intermediates, such as DCE/VC from the anaerobic degradation of PCE/TCE or CF/DCM from the anaerobic degradation of CT.
Adventus EHC-A
EHC-A is a liquid formulation the EHC product provided as a suspendable solid or an aqueous solution for easy application to existing wells or other networks of. EHC® is a controlled-release, integrated carbon and zero valent iron (ZVI) source that yields redox potential (Eh) in the -500 to -650 mV range. This Eh is significantly lower than that achieved when using either organic materials (lactate, molasses, and sugars) or reduced metal alone. Eh potentials in this range facilitate the timely and effective removal of normally recalcitrant chlorinated organics (e.g., CT, PCE) and other persistent compounds (e.g., perchlorate) without the formation of potentially problematic intermediates, such as DCE/VC from the anaerobic degradation of PCE/TCE or CF/DCM from the anaerobic degradation of CT.
Adventus EHC-O
The EHC-O product is an integrated source of slow-release oxygen, major-, minor-, and micro-nutrients, and a pH buffering agent. This combination facilitates the aerobic bioremediation of soils, sediment or groundwater environments impacted by various organic and inorganic compounds. For organic constituents amenable to aerobic biodegradation processes (e.g., petroleum hydrocarbons and certain pesticides/herbicides), EHC-O significantly stimulates the catabolic activity of the indigenous microflora, thereby accelerating the rate of contaminant removal.
