The availability of comprehensive effectiveness and capital and operational maintenance costs for these treatment systems will assist API member companies in planning pump-and-treat remediation systems for removal of BTEX and oxygenates from groundwa

12、ter. The compounds of primary interest Operating data were gathered from 57 field sites .throughout the United States. Treatment system profiles including capital investment, operating and maintenance costs, influent and effluent contaminant concentrations, and operating parameters (e.g., flow rates

13、, fouling characteristics) were generated for each site. While rigorous statistical analyses did not provide meaningful correlative data for system comparisons, a variety of summary statistics were useful for estimating costs and treatment effectiveness. Median investment costs and operating and mai

14、ntenance costs for air stripping systems operating at flow rates from 10 to 50 gallons per minute (gpm) were $1,627 per gpm and $2.80 per thousand gallons, respectively. Median costs for systems operating below 10 gpm were substantially greater. Median operating costs were approximately 40% greater

15、than design costs, a difference at least partially attributable to operating flow rates that were lower than design flow rates. API PUBL*4525 90 m 0732290 0098403 O m The air stripping systems studied generally achieved benzene removal effectiveness of 99% or more. IPE removal effectiveness was simi

16、larly high (98%; 3 cites), while MTBE removal effectiveness ranged from approximately 56% to 99% with a median removal effectiveness of greater than 91% (15 sites). Where design removal efficiencies were not met, biological or precipitated metal salt fouling were believed to be responsible. Fouling

17、was found to be a common problem with air stripping systems, although fouling prevention and/or treatment efforts were generally successful. Limited carbon adsorption system data indicated treatment costs similar to air stripping system costs operating at similarly low flow rates (50 2 $6.40 $44.88

However, the median values for actual costs derived from this database provide reasonable values for estimating treatment costs. The wide ranges associated with these data imply that any estimates based on this information can be viewed only as rough approximations. 22
