Treatability of subsurface-derived fluids from a former manufactured gas plant

Treatment of ground water from former manufactured gas plant (MGP) sites can be both costly and technically difficult. This paper presents results from a 3-month continuous pilot study (15 gpm average) which utilized physical separation processes, chemical oxidation systems, a fluidized biological reactor, carbon adsorption, and air stripping. The presentation will focus on operational data including removal efficiencies, process flexibility, full-scale design projections, and comparative costs between some treatment technologies. Construction of a full-scale treatment system utilizing the pilot test data is currently underway.
