Source of Cyanide in Water: The most commonly used form, hydrogen cyanide, is mainly used to make the compounds needed to manufacture nylon and other synthetic fibers and resins. Other cyanides are used as herbicides. The major cyanide releases to the water supply are discharges from metal finishing industries, iron and steel mills, and organic chemical industries.

Effects of Cyanide in Water: The US EPA has found short-term exposure to cyanide to potentially cause rapid breathing, tremors and other neurological effects when humans are exposed to cyanide relatively short periods of time. Chronic exposure causes weight loss, nerve damage and thyroid damage.

How to Remove Cyanide: Reverse osmosis filtration will remove 90-95% of cyanide from water, and is considered the Best Available Technology for cyanide-contaminated water. WECO reverse osmosis systems can be tailored for residential and commercial applications.
