Hydrogen peroxide to reduce sludge in effluent treatment

I am writing on behalf of a pharmaceutical company where I currently work. We have an on site effluent treatment plant to treat both industrial and domestic waste from site with a much greater percentage of the waste being industrial, about 7000 mg COD (max). Our effluent treatment plant currently uses an aerobic biological process to reduce COD but large amounts of excess sludge is being produced due to the high microbial growth rate in the aeration tank. We are currently looking into the possibility of using hydrogen peroxide as a pretreatment process prior to or after neutralization in order to reduce the COD of the incoming effluent and consequently reduce the amount of bio sludge required to treat the influent and the growth rate. I know this does not involve metal finishing but this seems like a helpful site and I would be grateful if you could advice about the use of this technology.

Thank you,

I have the same concern so I want to be updated in this topic.
