Abstract: In order to manage the risk that the water effluent may at times exceed the limits of the USEPA final Toxicity Characteristics (TC) rule which came into effect on September 25, 1990, a major oil company found it necessary to install a treatment system for the water effluent from a refinery. OHM Remediation Services Corp. was retained to provide the equipment and operating expertise to attain compliance prior to the deadline. Counter-current packed column air stripping was selected as the most economical method to render the water non-hazardous. Both operational and analytical data were obtained and compiled during operation of the system. This effort is presented with an emphasis on the design, instrumentation and controls, and performance of the air stripping process.
