John McLean’s first Water Treatment System Patent. Official March 14, 1972. John was working for Reynolds Metals when he invented this system. He went before the board at Reynolds when he was about to retire and asked if they had any interest in the invention. John was well respected and already produced 25 patents for Reynolds as a Lubrications Engineer. Reynolds let John keep his Iron System Invention.
With his iron system patented John incorporated his water treatment business. John and his wife Edna never advertised the company nor did they take any money, as Edna was always eager to point out. John’s hand crafted iron treatment produced many clients around Richmond and all by word of mouth.
John later invented another water treatment system, this time for sulfur removal. This patent was also licensed to Chemical Engineering Corporation. Both systems were successful, revolutionary and surpassed all other available iron and sulfur water treatments at that time.
