How do you treat hydrogen sulfide in industrial wastewater?
asked 2 March 2016 asked by Pierre_DEL ( points)
Hello, You can try hydrogen peroxide, which is a powerful and highly effective oxidant when used on sulfide; in terms of your installation, that would be upstream from the physicochemical treatment. Theoretical strength is 8 g of pure H2O2/g of S2, but in practice this concentration is closer to 12 g pure H2O2/g of S2 on urban wastewater effluent. You can give it a try using an 800-l cubitainer of H2O2 at 35%, but careful about safety and speak to the corresponding department in your WWTP, because it is a very powerful reagent that can turn explosive if it comes into contact with pure organic mater, e.g., oil leaking from a metering pump.
Hello, It would be useful to clarify a few specs regarding the orders of magnitude, i.e.: * "a lot of hydrogen sulphide": what concentrations? * "good results": what’s your goal (not exceeding a set threshold in an average 24-hr period)? Permanently? What is the current setting: flow control? Other? Effluent conditions /current treatment/objective—that will make it easier for us to give you tips. Good luck.
