Zimpro® Systems High Strength Industrial Wastewater Treatment

Wet oxidation treatment can be used to treat high strength waste streams in order to make them more suitable to conventional treatments, such as biological polishing, or as pretreatment for product recovery.

Wet oxidation destroys the large molecules in waste (e.g., phenol), converting them predominantly to carbon dioxide with some formation of low weight carboxylic acids such as acetic acid, which is highly biodegradable.

The effect of this treatment is to condition a waste that is:

toxic
reactive
refractory to biotreatment
or hazardous

into a waste readily suitable to biological treatment. Wet oxidation also achieves a gross reduction of the waste Chemical Oxygen Demand (COD), and reduces loading to any downstream treatment process.

In addition to waste destruction, wet oxidation can be used for chemical recovery by oxidation of organic contaminants.

Anoxic hydrolysis can be used for the destruction of contaminants that can by hydrolyzed without oxygen. Cyanide or phosphorous would be examples of such contaminants.
