ABSTRACT:
A purification process for industrial effluent containing dissolved dithiocarbamate is described. Before discharging the effluent, it is mixed at pH 6 to 8 with a soluble heavy metal salt and heavy metal dithiocarbamate thereby precipitated and the precipitate is separated from the effluent. By the process poisoning of fish in water courses into which the effluents are discharged can be avoided as can malfunctioning of sewage treatment processes handling the effluents.
