Electroplating technology is an important technological process at production facilities of various profiles. The electroplating baths are a source of hazardous emissions of toxic vapors and aerosols. In factories with electroplating sites, the crucial task is to eliminate hazardous emissions by applying an effective exhaust ventilation and air purification system for subsequent air discharge into the atmosphere. In this article two basic schemes for cleaning process emissions from electroplating baths were developed: a scheme with purification in scrubbers; a scheme with purification in scrubbers with pre-filtration. The advantages and disadvantages of each scheme were considered. Based on the amount of hazardous emissions and their dispersed composition, the purification efficiency of each scheme was calculated using the probabilistic method. In view of the calculations, a scheme for cleaning process emissions from the electroplating line with the highest purification efficiency has been identified.
Key words: Toxic vapors / aerosols / scrubber / pre-filtration / probabilistic method
