Development and modelling of a steel slag filter effluent neutralization process with CO-enriched air from an upstream bioprocess.

The main objective of this project was to develop a steel slag filter effluent neutralization process by acidification with CO-enriched air coming from a bioprocess. Sub-objectives were to evaluate the neutralization capacity of different configurations of neutralization units in lab-scale conditions and to propose a design model of steel slag effluent neutralization. Two lab-scale column neutralization units fed with two different types of influent were operated at hydraulic retention time of 10 h.
