Founded in 1984, KDF Fluid Treatment, Inc. is a technological leader in the fluid treatment industry. KDF® process media are high-purity copper-zinc formulations used in pretreatment, primary treatment, and industrial applications. KDF water filter media supplement or replace existing technologies to dramatically extend system life, reduce heavy metals, microorganisms, scale, lower total cost, and decrease maintenance.

Green Filtration

Patented KDF process media are 100 percent recyclable and contain no chemical additives. Hospitals, restaurants, municipal water treatment facilities, and homes rely on KDF process media to safely reduce or remove chlorine, iron, hydrogen sulfide, heavy metals, and bacteria from their water.

In the mid-1960s, Don Heskett was a consultant to Morton Salt, where he initiated the development of new, experimental carbon block technology. Then, in 1972, Don worked with Bill Steger to develop a working prototype of one of the water treatment industry’s very first non-electric water softeners. Although both developments were innovative, they were also ahead of their times.
In 1984, Don’s timing improved. In an experiment using cement as a binder for carbon cartridge filters, Don discovered—and "quite by accident," he adds—the powerful effect that a copper-zinc alloy could have on chlorine. At four o’clock in the morning, he used a brass ballpoint pen refill to stir some chemicals which contained chlorine. When he noticed that the red color which indicated the presence of chlorine had disappeared, his curiosity got the better of him and he spent the next day experimenting with different chemicals and various zinc-copper combinations until he was able to consistently replicate the same effect he had discovered accidentally.
He had discovered the value of the electro-chemical oxidation process known as "redox" treatment which, in his experiments, reduced chlorine to chloride.
