The proprietary ANTEXTM Soil Cleaning Process consists of a continuous wash unit and a continuous rinse unit. The wash unit encompasses a system consisting of the wash unit, a solution vessel, a spent solution (wash water) treatment system, a wash solution preparation vessel, and a filtration/separation device. The rinse system consists of the rinse unit, a rinse water vessel, a spent rinse water treatment system, and a filtration/separation device.

The wash solution additives are selected depending upon the types of contaminants present in the soil. The soil is excavated and continually fed into the wash unit. The wash solution is added continuously at a predetermined rate. The retention time (length of wash cycle) can be adjusted as needed to assure the most effective removal of the contaminants from the soil. At the discharge end of the wash unit, a filtration/separation device separates the soil from the wash solution. The spent wash solution, containing the extracted contaminants, is treated with a predetermined ANTEX chemical. After contaminant removal, the treated water is transferred back to the solution preparation vessel, ready to be reused in the next soil wash phase, thus providing a closed loop.

After separation of the washed soil, it is fed into the rinse unit and rinse water is added at a predetermined rate from the rinse water vessel. At the discharge end of the rinse unit, the soil and spent rinse water are separated. The clean soil is then placed directly onto the ground. The spent rinse water is transferred to the treatment system in which the remaining contaminants are removed with the predetermined ANTEX formulation. The treated rinse water is pumped from the treatment system to the rinse water vessel for reuse. The resultant sludge from the wash and rinse cycles is pumped to a dewatering device. The cleaned soil is redeposited.
