Electric Resistance Heating Remediation

Three phase heating and six phase soil heating are varieties of this technology.

Electric resistance heating remediation.

The team selected electrical resistance heating to remediate the source zone. 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. The erh technology is an ideal solution for both soil and groundwater remediation and the complete removal of.

Terratherm offers an advanced form of electrical resistance heating erh called electro thermal dynamic stripping process or et dsp. Erh has been widely applied and proven effective for free product recovery and enhanced vapor extraction at sites with volatile contaminants. Who we are trs group a 100 employee owned company with joint ventures in brazil china. 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.

They include metallic alloys nickel chrome iron chrome aluminum tungsten molybdenum and tantalum ceramic materials silicon. Electric resistance heat can be supplied by centralized forced air electric furnaces or by heaters in each room. The soil is heated by means of a grid of electrodes that conduct electricity. Injection of hot air can volatilize organic contaminants e g fuel hydrocarbons in soils or sediments.

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

An overview in the field of electrical resistance heating a variety of materials are available for use as heating elements. In erh alternating current is passed through a targeted soil volume between subsurface electrodes and the soil matrix resists. The resistance to electrical flow that exists in the soil causes the formation of heat. Electric current is passed through a targeted soil volume between subsurface electrode elements.

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.
