Application Of Ozone in Paints and Varnish
Paints and Varnish wastewaters are known for their intensive smell, presence of heavy metal, high BOD, high permanganate number, high phenol content, strong color etc. Ozonation at elevated pH in the pre-treatment have shown excellent results. A considerable amount of reduction in phenolic content, color, BOD, permanganate number, odor and heavy metal concentration has been observed in various tests and treat-abilities.
