The formed-in-place membrane filtration system offered by SBP Technologies, Inc. of Stone Mountain, GA was evaluated by the USEPA SITE Program. The SITE Program Demonstration was accomplished at the American Creosote Works site in Pensacola, FL in October 1991. The system effectively performed an 82% volume reduction, and removed greater than 95% of higher molecular weight PAHs and 92% of total PAHs from the permeate stream. The permeate stream SVOC concentration averaged 22.8 mg/L over the six-day period. This stream was determined to be acceptable for discharge to the local POTW. The membrane system tested was not very effective at removing lower molecular weight compounds (ca. 18%) such as phenolics. Of the total SVOCs present, ca. 75% removals were achieved. For each 2000 gallons treated, ca. 200 gallons of wash water were utilized; ca. 8% of contaminants were distributed to the washwater. Estimates of capital and operating costs are between $202 and $675 per 1000 gallons treated (not including costs of final disposal).
