ABSTRACT:
A device for removing hydrogen sulfide from well water having in situ activated carbon adsorbent regeneration. The device includes a tank with a water inlet, a water outlet and a steam outlet. The hydrogen sulfide adsorbent material is situated in the tank so that water entering through the water inlet must pass through the adsorbent material before exiting the water outlet. The tank also has a heating element which may be activated to boil water which is in communication with the adsorbent material. The water inlet, the water outlet, and steam outlet each have valves which are operated so that water may enter the tank and pass through the hydrogen sulfide adsorbent material and out the water outlet during water purification stage without any water going out the steam outlet. Additionally, during the regeneration stage, the water outlets and inlets are closed and the steam outlet is opened so that water boiled by the heating element will produce steam which will purge hydrogen sulfide from the hydrogen sulfide adsorbent material and the steam admixed with hydrogen sulfide will be removed from the tank via the steam outlet.
