Description:
The BESCORP Soil Washing System is an aqueous volume reduction system that utilizes trommel agitation, high-pressure washing, sizing, and density separation to remove lead, lead compounds, and battery casing chips from soil contaminated by broken lead batteries. The basic concept is to first liberate the lead/lead compounds from the larger soil particles by slurry agitation and spray rinsing and to then separate, by gravity, these heavy particles (greater than 6 sp. gr.) from the soil (sp. gr. 2.5). In a similar manner, the process segregates the casing chips (less dense than soil) by gravity. The remediation objective was to clean the gravel and sand fractions to the USEPA cleanup levels for the Alaskan Battery Enterprises (ABE) Site: less than 1,000 mg/kg total lead and less than 5 mg/L Toxicity Characteristic Leaching Procedure (TCLP) lead.
