Description:
This report analyzes the results of the SITE Program demonstration of BioTrol's Soil Washing System at the MacGillis & Gibbs wood treatment facility in New Brighton, MN. he contaminants of primary interest are pentachlorophenol (penta) and polynuclear aromatic hydrocarbons (PAHs). From tests with two soils (130 mg/kg and 680 mg/kg penta), it is concluded that the soil washer effectively segregates contaminated soil into a large fraction of relatively uncontaminated washed soil, a small fraction of fine clay and silt retaining about 30% of the original penta contamination, contaminated woody debris and contaminated process water. enta removal efficiency (RE) in the two tests, defined as: -(washed soil conc./feed soil conc.), are 87% and 89% (vendor's claim: 90%). he RE for polynuclear aromatic hydrocarbons PAHs is slightly lower at 83% and 88% in the two tests. iotreatment of the process water from the two soil washing tests degraded 91-94% of the penta; removal of PANs could not be determined. hile steady state was not achieved, the biological treatment of the contaminated fines in a Slurry Bio-Reactor suggested that greater 0% removal of penta and PAHs could be achieved with a fully acclimated system. ombined operating and capital costs for an integrated, full-scale system are estimated to be $168/ton of soil treated; incineration of the woody debris is a major cost factor.
