Waste water from a bakery containing sulfides

Published on by in Technology

Waste water from a bakery contains sulfides (possibly from eggs). Can oxidation take care of the sulfides in the water?

If yes, and the owner employs a blower/diffuser to increase oxygen in the water, how much air needs to be blown into the water to oxidize 1kg of sulfide?

  1. Hi Josphat,

    Just a couple of questions to get a better picture of your application:

    Are the sulfides soluble or insoluble?

    Oxidation using air tends to be very quite slow. Are you able to offer a large retention time in your existing process?

    Why do you need to remove the sulfides?
