The Pollution Control Financing Authority of Warren County (PCFAWC) owns and operates a regional landfill for the disposal of non-hazardous solid wastes in northwestern New Jersey. To achieve the required H2S concentration, the PCFAWC needed to install an LFG sulfur scrubbing system capable of removing approximately 1 ton/day of sulfur from LFG. After a thorough review of commercially available technologies, the PCFAWC selected LOCAT. This paper discusses the specific challenges encountered during construction and system operation. Data is presented on construction and operation costs as well as system performance.
