Objective The aim of the research project was the design, the testing and validation of a novel pollution peak equalization system upstream of iron-industry and connected activities waste water treatment plants. One selected as a typical study case, the acido-basic wastes from a metal finishing plant (pickling, degreasing, tin-plating and connected activities).The purpose of the technology to be tested is to reduce the extremely variable effluent pollution concentration peaks to facilitate treatment without recourse to dilution using clean water. The effluent to be treated is the result of steel sheet surface treatment (pickling, degreasing, tinplating, passivation after cold-rolling (SOLLAC Mardyck Works). Studying the dynamics of variations in effluent over a period will enable us to establish, simulate and evaluate by computer simulation various designs (number and volume of compartments in the tank) with a view to setting up a pilot plant. It is then proposed to investigate the possibility of improving the system by controlling the effluent in the plant on the basis of readings from in-line sensors (pH, titratable acidity or basicity, etc). The system will be optimized and its performance and advantages assessed and compared with those of a conventional homogenization tank or a much larger treatment plant designed to absorb the pollution peaks. A general report on design and application methods will be drawn up so that the technology can be transposed to other iron and steel units.
