A method of treating well water for purposes of desulfurizing the well water and making it palatable. The water is treated with an excess of acidified copper sulfate or other metal salt and delivered into the top of a treating tank which contains a neutralizing filter means. Copper sulfide is precipitated from the water and removed in the filter tank whereby sulfur-free neutral water is obtained. Any excess copper sulfate is precipitated as copper hydroxide and also removed in the filter. Periodically, the filter tank automatically backwashes itself to remove the copper residues or the filter may be manually backwashed if desired.

A method of treating well water for purposes of removing hydrogen sulfide from said well water comprising the steps of (a) conducting sulfur-containing water from a well, (b) acidifying a treating solution of copper sulfate to a maximum pH of 4 to prevent premature precipitation of copper hydroxide

A method of treating well water for purposes of removing hydrogen sulfide from said well water comprising the steps of (a) conducting sulfur-containing water from a well, (b) acidifying a treating solution of copper sulfate to a maximum pH of 4 to prevent premature precipitation of copper hydroxide and introducing at least a slight excess of said acidified copper sulfate into said water, (c) delivering said water and acidified copper sulfate in a non-aerated system into a treating tank atop a treating filter of neutralizing mineral, (d) forming copper sulfide and precipitating same from said water, (e) forming copper hydroxide in said tank above or within said neutralizing mineral from the excess of said acidified copper sulfate, (f) mechanically filtering said copper sulfide and said copper hydroxide with said neutralizing mineral, (g) and removing sulfur-free water from the bottom of said treating tank.
