H2O2 and biological wastewater treatment

Hi, I'm an engineer, designing biological processes for wastewater treatment. My question: Is it possible to treat a wastewater, containing a H2O2 concentration up to 300 mg/l with a conventional biological treatment process or will the H2O2 have an inhibiting/toxic effect on the bacteria?

Hi, Irina. I don't really have any experience in this, but considering that H2O2 is strongly antiseptic, yet readily decomposes, I would bet that strong aeration before biological treatment would be the best path.

Regards,

Hello Irina,

consider the chemical and the biological oxygen value.
