DEALKALIZERS Weakly acidic cation exchanger. Through dealkalization the hardness and the bicarbonate content of the water are reduced, thus typically reducing the salt content in the water by approximately 75%. Used for production of boiler water and district heating water as well as process water in breweries. Boiler water >> District heating water >> Breweries >>
Dealkalization at major Danish brewery
Plant description Flow rates for standard modules: 1-50 m³/h. The plants are manufactured as one-tank and two-tank plants. The tanks are of steel coated with polypropylene. A complete plant for production of boiler feedwater typically comprises dealkalizer, CO2 deaerator and softening plant. Plant survey >>
Advantages and references The need for blowdown of the boiler is considerably reduced compared to the use of softened water solely as boiler feedwater. If the water composition is suited for dealkalization, the method is suitable for large boilers and it is inexpensive in operation. When brewing the bicarbonate content is important. This can be adjusted by mixing dealkalized water and raw water. References >>
