MineralizationProcess Technology

Proven Solutions for High Quality Water

Omya offers cost effective, reliable solutions for mineralization and pH adjustment, compliant to local drinking water regulations. Our high purity minerals deliver the best results in process efficiency and water quality.
Omyalime is a high purity, highly reactive milk of lime used to balance the pH of the final drinking water. It is a cost effective, natural replacement for sodium hydroxide directly dosed into the final water stream. This raises the level of calcium bicarbonate in the water, and removes the need to degass excess CO2 into the atmosphere.

Efficient, Sustainable pH Balancing

Exclusively available from Omya, Semidol removes carbonic acid and filters impurities from drinking and process water. Made from purest dolomite, it is half-calcined for improved reactivity. It corrects low pH quickly, protecting water infrastructure from corrosion. Other filtration media can be directly replaced by Semidol for healthier water.
