Like the others, it would be useful to know the concentration of Formaldehyde COD indeed if the concentration are relatively low Biological system should cope with it. If the waste water is industrial with high concentration of formaldehyde it can be pre-treated by Oxidation methods. We offer AOP for these situation where the effluent can be totally oxidises (including ammonia if present) or the effluent can be pretreated before the biological system. AOP stand alone or AOP + BIO can be solution.
