Abstract
A scrubber and method for precipitating a sulfide in water which contains hydrogen sulfide or a mercaptan. The scrubber includes a sacrificial first metal anode and a second metal cathode which are in physical and electrical contact and suspended into the water to form an electrolysis cell of the anode, cathode and the water. The second metal is more noble than the first metal. Preferably the anode is iron and the cathode is stainless steel. When so constituted, the anode forms iron oxide which reacts with sulfur from the hydrogen sulfide or the mercaptan to form an iron sulfide precipitate. The anode and cathode may be coplanar and suspended in the water with a free-moving float which facilitates contact of the water with the anode, or may be rods which are tethered and twisted to form a twisted wire pair.
