Objective To minimize the chromium concentration in the effluent from the leather industry.The project will be divided into several subsectors: 1) Higher chrome uptake during the tanning process - the objective in this phase is to investigate the influence of a pretreatment with aldehydes or aldehyde releasing agents in order to increase the chromium uptake during the chrome tanning. 2) Improvement of the recirculation and possible re-use of chromium from the tanning liquor (high fixation) - the research will be concentrated on the effluents from high-fixation chrome tanning due to the special problems compared to conventional chrome tanning. 3) Reduction of chromium from the wet aftertreatments - the preventive measures to be carried out in order to minimize the chromium discharge from these treatments will be investigated. These are factors during the process like selection of syntans, dyestuffs and so on. Furthermore pH and temperature are important parameters to be investigated. 4) Chromium replacement - this phase will be investigated using combinations of primarily aluminium and Mimosa. Parameters that will be investigated are the concentrations of the tanning agents, temperature, pH, reaction time and on what stages the addition of the tanning agents will take place.
