Photo-Oxidation is perfect for pretreatment of toxic and/or persistent waste waters. UV-Oxidation of toxic and persistent compounds leads usually to a waste water with good bio-degradability by microorganisms. This offers the possibility to process the wastewater in the own company biology and avoids the high costs for external collection and processing. The best advantage is to combine Enviolet's AOP with the own already existing biological treatment plant, or sending it to the municipal biological wastewater treatment plant.
Most of these installations we have reliazed for chemical and pharaceutical industry.
Socalled strong wastewaters can be pre-treated in our photo-oxidation-plants, without increasing salt load, and pumped into the biological wastewater treatment plant.
Well known references are BASF (several units for pre-treatment), GSK (detoxification of e.g. Antibiotics), DOW (various AOP-plants for very different duties of advanced ocidation), Merck ( typically AOP for pretreatment of concentrates from chemical synthesis) and Atotech (advanced oxidation for elimination of chelates and recalcitrant organic amines).
