Laboratory and Pilot-Scale Evaluations of Physical/Chemical Treatment Technologies for MGP Site Groundwaters. Topical Report January 1989-May 1990

摘要

Treatability studies were performed to evaluate the treatment of Manufactured Gas Plant (MGP) site groundwaters using the following treatment processes: gravity separation, coagulation/flocculation, sand filtration, air stripping, carbon adsorption, and chemical oxidation. Treatment results for conventional parameters, inorganic compounds, metals, volatile aromatics, phenolics, and polynuclear aromatic hydrocarbons are presented and compared to regulatory limits associated with discharge to a Publicly Owned Treatment Works (POTW), discharge to a surface water body, or subsurface injection. Equipment costs as well as operating and maintenance costs are presented for several treatment strategies designed to achieve compliance with alternative discharge requirements.
