John also noted the mechanical properties of iron treatment resembled his original system’s iron treatment mechanics like no other. John McLean considered the McCoy Iron Removal System to be a breakthrough in technology for our family’s water treatment business and the industry.

The McCoy Iron Removal System removes 100% of 14ppm soluble and insoluble iron, 100% of 4ppm hydrogen sulfide, and neutralizes an acid pH of 6.5.ĭr. The McCoy Iron Removal System out-performed the MacCLEAN Iron System and is still treating that water today. The new system’s start-up produced amazing results. With John’s permission, the McCoy Iron Removal System replaced the MacCLEAN System as an experiment. The McCoy Iron Removal System was created.

Brian took on the challenge to develop an improved MacCLEAN Iron System and spent many months, after working hours, sometimes all night, until he found the answer. John and Brian began re-configuring the MacCLEAN Iron System and trying all means of improvements and additions with little result. The MacCLEAN Iron System components included: Iron Filter Tank with Control Valve and an air injector (“Micronizer”, “HydroCharger” or Air Charger) installed between the well pump and the expansion tank. He started testing and quickly learned the MacCLEAN Iron System is not capable of removing 100% of the iron present in his water. John found fault with the MacCLEAN system right away.

His daughter, Sandy McCoy, decided it was time to replace her father’s old iron system at his house with the MacCLEAN System. In 1998, John McLean was approaching ninety. He spent many of his days off from work with his grandfather in the lab, learning water chemistry and everything John could teach about designing and building water treatment. Brian labored for the company, servicing and installing his grandfather’s water treatment systems and learning all brands and products for water treatment. John McLean, began working for his family’s water treatment business.

This newly re-configured system proved quick and easy to install but never really removed iron as well as John’s original hand crafted and hand assembled iron system. The MacCLEAN Iron System became the company’s exclusive iron removal system from then on. John retained principle ownership until March, 2002.Īfter gaining control of the company, Sandy and Dan switched to using the pre-fabricated MacCLEAN Iron Removal System. John passed operation of the business to his daughter and son in-law, Sandy & Dan McCoy. John was in his seventies when he decided it was time to take a less active role in the company.

The original invention was then modified to become a mass manufactured product known as the MacCLEAN Chem.-Free Iron Removal System. In the early 1980’s Chemical Engineering Corp, an at that time small water treatment company in the mid west, purchased rights to John’s invention. Years later a simple idea prospered into a well known family owned water treatment business. This simple design proved to be a breakthrough in technology for iron removal treatment. John Oliver McLean patented his Iron Removal System that he invented in 1955 for his family and his home on the James River here in Richmond, VA.
