HEDP
The CUBLEN K series (HEDP) is a very good CaCO3 inhibitor, water hardness stabiliser and complexing agent for trivalent metal ions (for example Fe3+). Selected HEDP products are certified according to the North American standard NSF/ANSI/CAN 60 for use in the production of drinking water. In addition to aqueous products, HEDP is also available as a granular, dust-free solid with various active contents.
