The overall objective of this research project is to determine the feasibility of developing a knowledge-based system to improve the treatment of effluents arising from cold rolling and finishing area. On the basis of information and data on critical parameters of aqueous effluents and treatment processes, such a knowledge-based system will:

-Improve the performance in terms of efficiency, reliability, safety and operating costs of waste-water and emulsion treatment plants.

-Produce smaller volumes of treated water with lower concentrations of contaminants, thus reducing the impact of the aquatic environment.

Knowledge-based system technology has been available for several years but has never been applied to the treatment of steelworks effluents.

Cold rolling and finishing areas were selected because they produce relatively large volumes of liquid effluent from strip cleaning and rinsing processes.

The results of this feasibility study show that this relatively cheap technology is effective in improving the environmental performance of existing treatment processes and reducing operating costs and is a viable alternative to the introduction of new treatment processes, which have a high capital cost for development and installation. The application of the technology within the European steel industry would help to meet the more stringent environmental legislation without a significant cost implication.

The results obtained from the prototype software suggest that improvements in treatment plant performance of 15-20 % are achievable. In addition, there is a cost benefit that could produce a payback within two years for most systems.
