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.
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.
The plants are produced as one-tank and two-tank plants.
The tanks are made of steel and can therefore resist pressure fluctuations. They are also surface coated with PPA, a high-performance factory applied polyethylene coating. Thus, the filter tanks combine the strength of steel with the strong anti-corrosion properties of the PPA (C5-M).
A complete plant for production of boiler feedwater typically comprises
CO2 deaerator, and softening plant.
1.5-14 m³/h per modul one tank or two tanks mounted on the one frame
up to 50 m³/h with separate regeneration unit
