Abstract
The coking operation requires an environmental assessment including an examination of alternate strategies for handling wastewaters if maximum improvement of the environment is to take place. Coke plant wastewaters are typically saline, contain a broad range of organics, suspended solids, sulfides, ammonia, cyanide, phenolics, oil and grease, and pH values. Guidelines call for more than 90 percent reduction in ammonia, cyanide, and phenolics from their former levels in typical untreated process waters by 1977, with further control to reduce discharges by more than 99 percent. Different control strategies result in pollutant emissions to the air, water, and land. Due to the complexity of the problem an overall best strategy for the environment as a whole, an aggregate summation of these different residuals and their effects must be attempted. (PAG)
