Weak Acid Cation Resin for Dealkalisation

Lanlang® Weak Acid Cation Resin for Dealkalisation is a top-notch product with superior capabilities in treating water for various applications. Dealkalizers are acidic medium cation exchanges that are mostly used to treat water with significant bicarbonate hardness. Removing bicarbonate hardness reduces scale and corrosion, assuring the dependability of other water purification devices. The capacity of water to neutralize acid is measured by alkalinity. Depending on the pH of the water, there are three sorts of alkalinities: bicarbonate, carbonate, and hydroxide. The pH of bicarbonate (HCO3) ranges from 4.3 to 8.3. Bicarbonate is now the most common kind of alkalinity found in natural water bodies. The pH of carbonate (CO3) ranges from more than 8.3 to 10. When the pH is more than 10, there is hydroxide (OH) alkalinity.

The dealkalization of water refers to the removal of alkalinity ions from water. Chloride cycle anion ion-exchange dealkalizers remove alkalinity from water.

Weak Acid Dealkalization – When the ratio of water hardness to alkalinity is 1 or greater, a weak acid cation resin offers significant cost advantages. Weak acid cation resin resin exchanges hydrogen for the hardness associated with the water's alkalinity. Then degasification is used to remove carbon dioxide. Caustic may be added in low doses to raise the final pH level if desired.
