It has been a long time since I took chemistry as a engineering student so I am posting my question here.

I apparently have hyrdogen sulfide in my well water supply.  Its that nasty egg odor smell in the water.  The current setup to remove this is a chlorine (actually bleach) injection system followed by an activated carbon filter.

I was hoping to understand the chemical reaction/process that occurs with the system.  The sodium hypochorite (the bleach) reacts with the hydrogen sulfide in the water and makes something that the carbon filter can remove.

I was hoping someone could explain this process in detail.  So far all Internet searchs have led me with dull and basic explanations.

Thanks in advance.

Most likely sulfide is oxidized either to sulfur or sulfates. If to sulfates - you just have them in the water you drink. They are always present in water to some extent, just like chlorides and carbonates.

Thanks for the reply Borek.  I was hoping for a little more detail.  The chemical reaction process is interesting to me.
