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. 

Ex-situ Thermal Desorption

It is capable of treating various materials, including oil-base drilling mud and oily cuttings, sludge of oil separator, oil scum and waste activated sludge, sludge pits, heavy oily sludge and tank bottom sludge.

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

Ex-Situ Pile Thermal Desorption Technology (ESPTD)

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.

Stabilization Technology

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.

Ecopile Technology

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.
