During process COD is reduced and rest COD after oxidation is
transformed into BOD which can be eliminated in a biological
treatment.
Enviolet® AC
Further processes:
Elimination of active substances like:
Toxic compounds, antibiotics, hormones,
radio paque materials, chelators,
etceteras.
in production waste waters.
During process COD is reduced and rest COD after oxidation is

Plating bath recycling
a.c.k.- UV - evaporator -
Copper bath
Nickel bathFor classic plating baths and pulse
plating baths
Keep the bath always at 100 %:
Constant production
Less reject
Lowers expenses
ROI < 12 month for PCB-production with high workload
