Considerations on the Use bf Dithiocarbamates for the Removal of Metals from Water by :

As discharge restrictions become stricter and sludge dlisposal costs rise, traditional technologies for the removal of metals from plating shop wastewater such as lime and ferric chloride become increasingly less attractive. One technology that is of use of dithiocarbamates to complex a highly insoluble, dense sludge, effluent water and greatly reduced sludge volumes. Despite the benefits available from dithiocarbamate technology, certain practical problems to the implementation of a dithiocarbamate treatment program exist. This paper examines some of these problems and offers potential solutions, including some case histories.
