SO2 + 2H2O + NH2Cl --> NH4+ + 2H+ +Cl- + SO4 – 2 The theoretical dosage for dechlorination requires 0.9 mg/L of sulfur dioxide for every 1 mg/L of total chlorine residual to be removed. In most operating situations, the feed rate will be 1:1 to ensure all chlorine is removed. The contact time (assuming good mixing) is only about 2 minutes.

Why do my Farts Smell like Rotten Eggs, Sulfur or Sewage?
Speaking of farting, the smell is usually horrible but you will obviously notice a difference when it is foul smelling. One such type of smell is that of sulfur. The smell of sulfur is that of a rotten egg or that produced from underneath the ground in geothermal stations. More particularly, you will talk of hydrogen sulfide gas.
