Heavy metals and metallic compounds can accumulate in the environment and have an impact on people’s health. In very small amounts, many of these metals are necessary to support life, but 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. Metallic compounds containing molybdenum and zinc were developed as replacements for chromium, and are still allowed for use as cooling water inhibitors in many locales. However, as evidence builds regarding potential negative health effects of these metals, many municipalities are banning or severely restricting their use as cooling water treatments.
Chemtex EV series Green Program inhibitors and dispersants are formulated using all-organic components and contain no heavy metals. EV series inhibitor packages are not only eco-friendly, they provide outstanding scale and corrosion control. EV series inhibitors truly offer the best of both worlds.
