To remove the sulphides from the water, you could add a dose of FeCl3 directly into the reactor. By adding iron chloride, the hydrogen sulphide is converted to a slightly soluble iron sulphide with formation of hydrochloric ,acid, (HCl). This reaction causes the ,pH value, to drop slightly, so that the water remains at least as corrosive.
