KDF® Process Media Control Microorganism Growth

KDF® media are incorporated into carbon blocks and other matrices for bacteria control and scale reduction.

The oxidation/reduction potential (ORP) shift by a factor of -300mV or more for water filtered through redox media controls microorganism growth. Treating water reduces bacteria and other microorganisms by disrupting electron transport, causing cellular damage. KDF process media also kill bacteria by direct electrochemical contact and by the flash formation of hydroxyl radicals and hydrogen peroxide, both of which interfere with a microorganism's ability to function.

• A major plastic injection molder uses KDF media to treat cooling water for a 60,000 sq. foot plant. Mineral hardness scale is virtually eliminated at about 25 percent of the cost of chemicals, and none of the heat exchangers have been replaced. With chemical treatments, scale continues to form in the cooling towers, causing damage to the heat exchangers, which often results in expensive repairs. KDF redox alloy media provides an effective, less costly alternative to chemical treatments.
• Major municipal cooling towers depend on KDF media to effectively control algae and bacteria, without the use of chemicals harmful to the environment.
