Basis for design of industrial wastewater treatment plants
- Univ. of Texas, Austin
Designs for wastewater treatment plants associated with petrochemical production and petroleum-refining facilities are most reliable when wastewaters have been fully characterized and the performance characteristics of alternative treatment processes have been fully evaluated. Physical-chemical treatment is and will continue to serve as an important adjunct for pretreatment of specialty streams. While oxygen requirements can be established in a fairly forthright manner, bench-scale units do not lend themselves to meaningful prediction of sludge production. With these wastewaters, designers mayhave to use sophisticated concepts to ensure biological removal of ammonia nitrogen. High concentrations of amines may present particular challenges. Treatability studies can identify waste streams and perhaps even component discharges that can be removed or pretreated to promote nitrification of the total wastewaters. An appropriate treatment sequence for a particular wastewater treatment and disposal requirement can only be developed after detailed treatability studies have been conducted involving biological treatment, chemical addition, powdered activated carbon addition, postfiltration, and fixed-bed carbon polishing. The applicability of the activated carbon process in treating industrial wastewaters, for example, is contingent on many factors, including the amenability of the dissolved constituents to sorption, the presence of other substances that enhance or impede the sorption process, the soundness of engineering,, the degree of pretreatment, and the proper operation and maintenance of the system. As activated carbon was one of the primary processes factored into the development of the 1983 BAT guidelines for many industrial categories, some of which have been remanded by the courts, it is important to fully understand the process and its limitations. 12 figures, 1 table.
