Physical Modeling of LNAPL Remediation from Porous Environment using InSitu Thermal Heating method – Electrical Resistance Heating
The pilot system for thermal cleaning of LNAPL contaminants consists of an electronic central controller and equipped multiple temperature array sensors, a voltage measuring network, current and electric power measuring units, Qualitative sensors for vapor monitoring and sensor for monitoring the suction pressure of liquids and vapors; was designed and built.
In this system, Various soil LNAPL contamination scenarios and LNAPL pilot cleaning by ERH method were tested by equipping three-phase isolated power supply, groundwater pumping system, gas and vapor suction unit, vapor refrigerant and condenser and control switches.
Uses and applications
Pilot study of ERH method before implementation on the infected site to achieve optimal design of ERH system elements and effective cleaning of LNAPL contamination
Features and benefits of ERH Remediation
High efficiency in LNAPL cleanup
Need a short time to clean
Effective in fine sediments
Applicable to active areas and sites• Ability to integrate with other cleaning methods
