CROMOGENIA UNITS offers an ECOFRIENDLY UNHAIRING revolutionary
system. This process reduces sulfide
down to 0.2% and results in less polluted
residual baths, thus contributing to
sustainability. Residual baths have
lower COD and BOD values, less sludge
formation and less sulfide content, thus
avoiding odor and the formation of
hydrogen sulfide.
