Gilbride Electric Has Unique Experience and Expertise in the
industry with Electrical Resistance Heating (ERH)
Having worked with such companies as
McMillan McGee Corp,
Gilbride Electric offers Electrical Resistance Heating (ERH). ERH
has been widely applied and proven effective for free product
recovery and enhanced vapor extraction at sites with volatile
contaminants such as VOCs, CVOCs, and NAPLs, and is applied at low
and moderate temperatures. The below is an example of this process:
What is Electrical Resistance Heating (ERH)?
electric current is passed through the soil, the resistance it
encounters causes the soil and fluids to heat up. The current flows
from one electrode to another, primarily through the soil water.
Once the water boils off, electrical conductivity becomes negligible
and heating ceases; thus, water is added at each electrode to keep
them from drying out. Heat-up with ERH is limited to the boiling
point of water.
Electrodes are installed in wells throughout the
contaminated soil and groundwater volume. The
electrode array is connected to a Power Delivery
System unit that uses standard, readily available
three-phase power from the grid. The process
begins by passing current between electrodes
causing the soil temperature to rise. This
increased temperature results in the volatilization
of contaminant compounds into the vapor phase
for removal with vapor extraction techniques.
Comprehensive computer controls are used to
regulate and optimize the thermal response of
the target formation.
We welcome the opportunity to earn your trust and
deliver you the best service in the industry.
