Description:
A computer-aided design procedure for the preliminary synthesis of wastewater treatment and sludge disposal systems is developed. It selects the components in the wastewater treatment and sludge disposal trains from a list of candidate process units with fixed design characteristics so that criteria on effluent quality, cost, energy, land utilization, and subjective undesirability are best satisfied. The computational procedure uses implicit enumeration coupled with a heuristic penalty method that accounts for the impact of return sidestreams from sludge processing. The programmed version of the design procedure, called EXEC/OP, has been interfaced with the unit process subroutines contained in a previously EPA developed system evaluation program known as EXECUTIVE. A number of case study design problems are presented to demonstrate the versatility of EXEC/OP. Included among these is a preliminary cost/energy-effectiveness analysis for a hypothetical design problem containing over 15,000 alternative system configurations.
