The following technology profile has been reproduced from the SITE Technology Profile document, 7th edition. The SITE profile has been supplemented by MVA Consulting Inc. using information obtained from the vendor or from other SITE publications, referenced at the end of this file. The BioGenesis processes use specialized, patent pending equipment, complex surfactants, and water to clean soil, sediment, and sludge contaminated with organic and inorganic constituents. A truck-mounted batch unit, processing 40 yards per hour, washes soil particles 10 mesh and larger. A full-scale, mobile, continuous flow unit cleans sand, silt, clay, and sludge particles smaller than 10 mesh at a rate of 20 to 80 yards per hour.
Auxiliary equipment includes tanks, dewatering and water treatment equipment, and a bioreactor.
Extraction effi-ciencies, per wash cycle, range from 85 to 99 percent. High contaminant levels require multiple washes. Water, BioGenesis cleaning chemicals, and soil are loaded into the gondola. Aeration nozzles feed compressed air to create a fluidized bed. The resulting slurry is agitated to release organic and inorganic contaminants from the soil particles.
