Technology evaluation report: Biotrol Soil Washing System for treatment of a wood-preserving site. Volume 1
The report presents and evaluates the extensive database from the SITE Program demonstration at the MacGillis and Gibbs wood treatment facility in New Brighton, MN. Soil washing and segregation, biotreatment of contaminated process water, and biodegradation of a slurry of the contaminated fines from the soil washing were evaluated over several weeks of operation. The contaminants of concern were pentachlorophenol (penta) and polynuclear aromatic hydrocarbons (PAHs). The results indicate that the soil washer effectively segregates contaminated soil into coarse, relatively uncontaminated sand constituting the largest output fraction and a much smaller fraction of fine clay/silt particles retaining about 30% of the original contamination. Penta removal efficiency from the feed soil is 87%-89% (vendor's claim: 90%). Contaminated woody material is also segregated. Operational variations and their impact on output qualities and quantities are described. Biotreatment of process water from the soil washing successfully degraded 91-94% of the penta. The results for the slurry biological treatment of the contaminated fines indicated that >90% removal of penta and PAHs probably can be achieved with a fully acclimated system operating at steady state. Combined operating and capital equipment cost for an integrated system are estimated to be $168/ton of soil treated. Incineration of the woody debris is a major cost factor. Costs are also presented by process since specific applications may require different configurations of the three units.
