Treatment of rinsing water for galvanic baths - with maintenance of a constant electrolyte concn.

摘要

Method for rinsing water treatment for galvanic baths is based on electrodialysis. The electrolyte and rinsing water circulation is arranged so that the process prods. are sepd. from the rinsing water at constant voltage in the diluate and the treated soln. is returned to the process after the concn. stage. USE/ADVANTAGE - Used in galvanic plating installations, esp. in situations where electrolytes must contain organic additives. It requires no additional chemicals for the regeneration process. It is more economical and environment-friendly, and requires less elaborate electrolyte check.
