Alkalinity is the capacity of water to resist changes in pH that would make the water more acidic. A water body with a high level of alkalinity has higher levels of calcium carbonate, CaCO3, which can decrease the water’s acidity.

RA-330 De-Alk Resin is a macroporous weak acid cation exchange resin and is used for dealkalisation and deionization in water.
