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.
Electric resistance heating remediation.
Et dsp has been field proven on over 30 successful projects by our technology partner mcmillan mcgee corporation.
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.
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.
The soil is heated by means of a grid of electrodes that conduct electricity.
In erh alternating current is passed through a targeted soil volume between subsurface electrodes and the soil matrix resists.
Cascade thermal is a leader in the development and implementation of onsite and in situ thermal remediation of toxic contaminants.
Electrical resistance heating elements.
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.
Electric resistance heat can be supplied by centralized forced air electric furnaces or by heaters in each room.
Terratherm offers an advanced form of electrical resistance heating erh called electro thermal dynamic stripping process or et dsp.
Three phase heating and six phase soil heating are varieties of this technology.
They include metallic alloys nickel chrome iron chrome aluminum tungsten molybdenum and tantalum ceramic materials silicon.
Electric current is passed through a targeted soil volume between subsurface electrode elements.
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.
With this technique the soil is heated to the boiling temperature of water which volatilizes the contamination.
