Heavy Metals and the Environment
Heavy metals can accumulate in the environment and have a negative impact on people’s health. In very small amounts, many of these metals are necessary to support life. In higher concentrations they become toxic.
Hexavalent chromium was the standard corrosion inhibitor used in cooling water inhibitors for years, but was banned from this use when it was determined to be carcinogenic. Molybdenum and zinc were developed as replacements for chromium and are still allowed for use as cooling water inhibitors in many locales. With increased scrutiny over chemicals in the environment, many municipalities are restricting their use in water treatment products.
Chemtex EV series Green Program inhibitors and dispersants are formulated using all-organic components and contain do not heavy metals. These inhibitor packages are not only eco-friendly, they provide outstanding scale and corrosion control. They offer the best of both worlds.
