Ozone Monitor Pharmaceutical Applications - Application Note

Ozone treatment of wastewater reduces the usage of energy, water, utilities and chemicals, and provides an effective alternative to traditional chemical treatments and older technologies. Pharmaceutical wastewater containing from 0.5% up to 10% formaldehyde or glutaraldehyde can be treated using ozone or ozone/peroxide/UV combinations. Up to 55% reductions in chemical oxygen demand (COD) levels are observed for solutions containing either formaldehyde, glutaraldehyde or a mixture of the two aldehydes when these solutions are treated using ozone or ozone/peroxide/UV combinations.
