This report summarizes the utility and application of SBP's membrane system to the treatment of organic contaminated wastewater. This analysis utilizes information from the Superfund Innovative Technology Evaluation (SITE) Program's demonstration at the American Creosote Works wood preserving site in Pensacola, Florida as well as data from other SBP investigations. Conclusions were reached concerning the technological effectiveness and economics of the process and its suitability for use at other sites and with other waste waters.
During the SITE demonstration, operations were carefully monitored to establish a database against which the vendor's claims for the technology could be evaluated. These claims were that the filtration system would (1) provide an 80% volume reduction for the contaminants in the feed stream; and (2) achieve 90% removal of semivolatile contaminants. based on a comparison of the concentrations in the feed stream and those in the permeate from the filtration system. Based on the demonstration study using the system as configured and as used, an 83% reduction in the volume of the contaminated feed water was achieved. However, the system achieved a 74% overall removal of the designated semivolatile components, which included low molecular weight phenols and polynuclear aromatic hydrocarbons (PAHs). The filtration system was much more effective at removing the PAHs than phenols. The average removal efficiencies were 92% for PAHs and 18% for phenols.Capital and operating costs for the system are estimated to be between $220 and $1,740 per thousand gallons (on an annual basis), dependent on the type and magnitude of contamination encountered in the waste stream.
