How to oxidize sulphide in wastewater effluents of tanneries with hydrogen peroxide?
//= $frontData["question_content"] ?>
Hi, I have a question
regarding sulphide removal from wastewater effluents of tanneries.
effluent (300 mc/d) flows in a tank, where it stays for about 14 hours.
sulphide value is very high: 610 mg/L; pH =12.
like to use hydrogen peroxide to oxidize sulphide to sulphate; I am, also,
considering the possibility of install blowers at the bottom of the tank, in
order to reduce the daily dose of hydrogen peroxide.
is to obtain an effluent with 120 mg/L of sulphide.
something I was hoping you could clear up for me: what is the right
concentration of dissolved oxygen to ensure a constant high-performance
treatment? What is the correct dosage of hydrogen peroxide to be used with this
concentration of dissolved oxygen?Thank you
