How do chelates work?

'Chele' is Greek for crab's claw

Crab's claw
 

As the word 'chele' implies, chelates seize a metal ion and control it, making it very difficult for another substance to liberate it.

Dissolvine® chelates form strong, water-soluble complexes that prevent undesirable precipitation, dissolve scale deposits and optimize oxidation processes. Our chelate product range includes chelating agents that bind and control metal ions, as well as metal chelates that introduce the right form of metal ions into a product or process.

For example, metal cations like calcium, magnesium and barium can form low water-soluble salts with carbonates, sulfates and phosphates that precipitate out of acqueous systems. These precipitates form scales that are extremely difficult to remove and reduce the efficiency of boilers and chemical processing equipment. When Dissolvine® chelating agents are added to these systems, they complex the metal ion into a water-soluble form and dissolve the scale deposit so that it is removed in the cleaning process.
