Persulfates for soil and groundwater remediation

Terramend® Reagent

Terramend® aerobic bioremediation reagent is a cost effective treatment technology for soils impacted by organic compounds. The Terramend® technology is advantageous because it can often be applied without excavation, generates no odors or leachate, and does not result in soil bulking (1-3% soil mass application rates typical).

An independent audit conducted by the U.S. EPA concluded that the technology represented a safe, effective, and cost-efficient means of treating soils (US EPA/540/R-95/536 July, 1996).

Two Terramend® formulations are available and selected based on site conditions and targeted contaminants. Terramend® Carbon treats soils containing recalcitrant compounds, including polycyclic aromatic hydrocarbons (PAHs), phthalates, and chlorophenols (including pentachlorophenol). Terramend® Inorganic treats biodegradable compounds, including BTEX, GRO, DRO, and TPH.

We will develop an appropriate dosing level and treatment approach for your site, based on contaminant mix, remedial goals and other site specific factors.

KEY BENEFITS

  • Hydrophilic character
  • Balanced range of nutrients
  • Improved ecology
  • Accelerated treatment

EXAMPLE CONTAMINANTS

  • Petroleum
  • Phtalates
  • Selected herbicides
  • Chlorophenols

Key functions

  • In situ landfarming
  • Ex situ treatment cells or windrows

TECHNOLOGY: Aerobic bioremediation

Aerobic bioremediation is the addition of oxygen and nutrients to accelerate naturally occurring bioremediation through natural biological processes. The process helps facilitate the conversion of biodegradable compounds to CO2 and H2O.

Terramend® application guides

We answer your frequently asked questions on the use of Terramend® technology for in situ and ex situ treatment. This includes topics such as process equipment, required soil properties, temperature in the treatment process or considerations for clay soils.

Terramend® Reagent improves natural bioremediation by adjusting conditions in the soil matrix to promote biodegradation of the target substance. Terramend® bioremediation is typically applied as a soil treatment process driven by an agricultural tractor.

Terramend® webinars

Dr. Alan Seech presents an overview on the Terramend® Reagent family for the in situ and ex situ treatment of soils impacted by a wide range of contaminants such as PCP, PAHs, phtalates and petroleum hydrocarbons.

Evonik’s laboratory created the KLOZUR® field test kit to provide a quick and reliable measurement of persulfate in the field.

There are two different kits available, depending on the activation method used. Each kit is capable of running ten tests and has a measurement range of 1g/L to 100g/L, with a theoretical accuracy of ±1g/L and ±2g/L respectively.
