reducing formaldehyde concentration in pharmaceutical industry waste water using oxidation in present of sodium hydroxide

formaldehyde containing waste water is detoxified by treating the waste water with hydrogen peroxide or ozone in the presence of alkali at an initial temperature of 10-35C. In an alternative and preferred form of this study the waste water is ozonized for about 180 minand then about 75% of the formaldehyde is converted to the formic acid and methanol
