Those processes, which use water whether as processing or heat exchange medium are susceptible of suffer scaling problems due to that waters contains concentrations of alkaline earth metal ions, particularly calcium and magnesium, even when high purity treated waters are used, causing serious problems on the heat transfer surfaces of steam generators or in the water transfer pipelines.
Boilers, Heat exchangers, Evaporators, cooling towers, wood pulp digesters or filter cloths are some examples of equipment affected to this problem.
One method of reducing or eliminating this scale is to reduce the effective concentration of the cation by its formation of a soluble chelate.
The use of chelating agents as DABEERSEN products, are effective to remove and prevent scale formation in operating boilers, and therefore to reduce possible repairs or accidents.
