Economic planning in industrial wastewater systems using O.R. techniques and WODA package

This paper is centered on the development of a computerized framework to assist in the management of a river basin industrial wastewater system. It is applicable to rivers following a Dobbins type model and the quality parameters under surveillance are the Biochemical Oxygen Demand (BOD) and the Dissolved Oxygen (DO). The WODA commercial package was used and adapted for the attainment of 4 BOD and 1 DO standards, using dynamic programming. Geometric programming was used to select the minimum cost preliminary treatment design of a plant. Other pollution abatement measures considered are flow augmentation and artificial aeration. A ‘compromised’ minimum cost solution between a completely centralised allocation of pollution abatement effort and a single company most economical solution is determined.
