Electric Resistance Heating Remediation

With this technique the soil is heated to the boiling temperature of water which volatilizes the contamination.

Electric resistance heating remediation.

The team selected electrical resistance heating to remediate the source zone. The soil is heated by means of a grid of electrodes that conduct electricity. Three phase heating and six phase soil heating are varieties of this technology. Electrical resistance heating is an extremely rapid form of remediation with case studies of effective treatment of soil and groundwater in less than 40 days.

Et dsp has been field proven on over 30 successful projects by our technology partner mcmillan mcgee corporation. Electric current is passed through a targeted soil volume between subsurface electrode elements. Cascade thermal is a leader in the development and implementation of onsite and in situ thermal remediation of toxic contaminants. Erh has been widely applied and proven effective for free product recovery and enhanced vapor extraction at sites with volatile contaminants.

The erh technology is an ideal solution for both soil and groundwater remediation and the complete removal of. They include metallic alloys nickel chrome iron chrome aluminum tungsten molybdenum and tantalum ceramic materials silicon. Injection of hot air can volatilize organic contaminants e g fuel hydrocarbons in soils or sediments. Electric resistance heat can be supplied by centralized forced air electric furnaces or by heaters in each room.

Electrical resistance heating erh is an aggressive in situ thermal remediation technology that can simultaneously treat chlorinated solvents in unsaturated and saturated soil perched groundwater tables and low velocity aquifers. In erh alternating current is passed through a targeted soil volume between subsurface electrodes and the soil matrix resists. Safe celebrating 20 years of thermal remediation excellencefast contaminant reductions of more than 99 in 3 to 6 months of heatingcertain decades of innovation and r d supporting heating solutions at lower costsguaranteed our safe proven technologies ensure that sites are clean. We design build and operate projects from concept to completion using thermal conduction heating tch steam enhanced extraction see electrical resistance heating erh and combinations of the technologies above.

Terratherm offers an advanced form of electrical resistance heating erh called electro thermal dynamic stripping process or et dsp. Room heaters can consist of electric baseboard heaters electric wall heaters electric radiant heat or electric space heaters it is also possible to use electric thermal storage systems to avoid heating during times of peak power demand. Electrical resistance heating erh is an intensive in situ environmental remediation method that uses the flow of alternating current electricity to heat soil and groundwater and evaporate contaminants. Who we are trs group a 100 employee owned company with joint ventures in brazil china.

In the last decade electrical resistance heating erh has gained popular application for in situ thermal remediation of organic contaminants due to its high heating efficiency large radius of influence etc.
