5. Environmental impact and safety
5.1 Environmental impact of the process
A zinciferous waste treatment unit using the REZEDA process, such as the TREZ unit, has only a negligible impact on environmental quality if appropriate effluent management and treatment measures are implemented, such as :
aqueous effluent treatment and analytical monitoring before discharge into the environment;
air suction from the various storage tanks, collected and washed before discharge into the atmosphere, to prevent dilution of the gases produced by electrolysis (mainly oxygen).
The only effluent from this process is the salt water obtained after neutralization of the process water, which can be discharged into the natural...
