ERADI(Ca)TE Supplier & Distributor

ERADI(Ca)TE – A Solution for Iron Hydroxide and Hard Water Scale Control

ERADI(Ca)TE is a descaler, a specialty water conditioner designed to prevent hard water scale build-up.  Common hard water scale formation is commonly the result of calcium carbonate precipitation and accumulation in equipment employing hard water.

ERADI(Ca)TE will bind with calcium, magnesium and iron, preventing the formation of common hard water scale.   Commonly used to prevent hard water scale build-up in down hole O&G applications where EDTA chelators would be recommended and/or normally used.

ERADI(Ca)TE is also available as an acid, offering an effective and economical option to Citric Acid.
