THE EFFECT OF ORGANIC-REACTIONS IN A COLLECTION SYSTEM ON WASTE-WATERTREATMENT-PLANT PERFORMANCE

Biological reactions within the sewer play an important role in establ ishing the water quality characteristics of combined sewer overflow an d of the sewage entering a wastewater treatment plant A simulation mod el that shows the effects of reactions in the collection system on was tewater treatment plant performance has been developed. A series of nu merical experiments was conducted to illustrate the features of the mo del, and the potential benefits of the approach. The study also serves to identify areas in which the models need to be improved.
