As a responsible organization, Jereh Environmental Management Group manages the services on soil remediation polluted by organic substances and heavy metals. We have an experienced engineering team, practical technologies, customized equipment manufacturing, as well as engineering design, contracting and operation qualifications for different projects. Targeting different objects and the situation of site to be repaired, we can provide integrated environment remediation services from site investigation, risk assessment, technical consulting, engineering design and contracting, to project implementation, acceptance and commercial operation.
Jereh EMG can provide rapid and economical treatment for soil and underground water polluted by TPH, PAH, POPS, TCCD, volatile organic compound (VOC), heavy metal and so on. Guarantee the polluted soil after treatment, ground and underground water comply with relevant national standards, eliminate or reduce environmental risk, recover the recycle value of repaired land.
■ Core Technology
Ex-situ Thermal Desorption
For the soil contaminated or oily waste with volatile or semi volatile and less volatile organic pollutants such as petroleum hydrocarbons, pesticides, polychlorinated biphenyls, etc. Through indirect heating and direct fire thermal, target contaminant is volatilized, separated and removed from the soil by controlling system temperature and process time. Monitoring during the whole operation can guarantee the safety.
Indirect Fired Thermal Desorption Technical Process
Direct Fired Thermal Desorption Technical Process
In-Situ Thermal Desorption Technology (ISTD)
ISTD is used for contaminated sites which are not easy to excavate or has buildings above ground such as deep soil, soil under buildings, etc. ISTD is applicable to volatile, semi-volatile and non-volatile organic pollutants such as petroleum hydrocarbons, pesticides, PCBs, etc.
In-Situ Thermal Desorption (ISTD) Technical Process
ESPTD is used for already excavated soil or for large quantities at shallow depths. Applicable to volatile, semi-volatile and non-volatile organic contaminants such as petroleum hydrocarbons, pesticides, polychlorinated biphenyls and other contaminated soils.
Ex-situ Pile Thermal Desorption Technical Process
Solidification / Stabilization Technology is used to immobilize the toxic heavy metals (chromium, cadmium, copper, lead, zinc, mercury, arsenic, nickel, etc.) contaminated soil, including agent injection and agent mix technology. Using of physical or chemical process, it can change the valence state of the heavy metals in the soil, reducing the toxicity, and prevent them from migrating and diffusing in the environment. Jereh EMG can provide customized solidification/stabilization agentia formula and integrated solutions for heavy metal remediation, as well as the engineering services for contaminated soil remediation.
Solidification & Stabilization Ex-Situ Agent Mix Technical Process
Ecopile technology is used for the soil contaminated with petroleum hydrocarbons, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, pesticides, etc. It adopted the some bio-phytoremediation principles to achieve rhizosphere remediation which adds organic matter degradation flora and nutrients to loose and ventilate the soil.
