Dispersion technologies are used in the water treatment chemical segment for dispersing scale-forming salts in boiler water and cooling water and preventing them from sticking to parts of the water system such as pipes and heat exchangers.
For example, if cooling water has a high concentration of dissolved calcium, magnesium or other components that cause water hardness, substances that are insoluble in water, such as calcium carbonate and magnesium silicate, crystallize and precipitate out of solution to adhere to the metal surface, agglomerating to form deposits.
Dispersion technologies combat this because a component of the added chemical sticks to the very small particles as they begin to precipitate out and prevents the aggregation and coarsening of the crystals. Kurita uses these dispersions technologies in the development of descaling agents.
