Potable & Natural Water Treatment by Omya
In order to raise the quality of natural water to a potable level, i.e. to a level acceptable for human consumption, we use limestone grades to adjust the pH value, to remineralize the water, or to reduce the water's hardness.
The grade and types of calcium carbonate Omya is offering in the treatment of potable water are defined by the European Standard EN 1018 or by local (by country) standards.
Eutrophication darkens the water and causes algal bloom, odor and the disappearance of fish from the area. We can use Omya calcium carbonate products to limit the eutrophisation. The products decrease excess nutrients (phosphate, nitrate) in water by adding Ca ions, which subsequently increases the clarity and quality of the water.
