  • What’s the Temperature? Thermal Modeling and its Importance in Thermal Remediation

    What is a model? A beautiful person who struts down a run way, a scaled down sculpture of the Empire State Building, or a series of equations that describe some phenomenon? Did you guess all of the above? Gold star! Models come in many different shapes and sizes. In the environmental consulting and remediation industry, the word “model” often refers to a numerical model. Numerical ...

  • Case study - Mobile remediation system

    OVERVIEW A large consulting and contracting firm owns and operates several ex-situ Thermal Desorption Units (TDUs). Each single-load Thermal Desorption Unit has the capacity of desorbing 15 tons of soil per hour at a temperature of 400°F - 900°F. These Thermal Desorber Units have been designed to operate on both chlorinated and non-chlorinated RCRA, CERCLA, and private industry ...

  • Mold Remediation Guidance For Indoor Environment

    Remediation contractors are generally very conscientious, trying hard to bring each project to a condition where it will pass “clearance  testing” (the  Post-Remediation  Verification  [PRV] inspection) on the first try. Sometimes the cleaning attempts are unsuccessful. This will certainly cost the contractor additional cleaning ...

  • Thermally Enhanced Soil Vapor Extraction

    Introduction Thermally enhanced SVE is a full-scale technology that uses electrical resistance/electromagnetic/fiber optic/radio frequency heating or hot-air/steam injection to increase the volatilization rate of semi-volatiles and facilitate extraction. Thermally enhanced SVE is normally a short- to medium-term technology. Electrical Resistance Heating Electrical resistance heating uses ...

  • Eastern Montana - Remediation below operating facility

  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...
