  Process for removing bicarbonate of soda from water.



   One is often forced to have to use water for industrial and boiler feeding purposes, which naturally contains bicarbonate of soda. Since such water at boiling forms single carbonate of soda or soda by releasing carbonic acid, care is taken to ensure that this is particularly harmful to the boiler operation.

   So far, it has helped by adding calcium chloride to such waters in addition to lime to remove the bicarbonates. 11m after the sodium bicarbonate

But this method also has its disadvantages. since calcium chloride has a strong corrosive effect, especially on sheet iron, and the reaction product sodium chloride or table salt can also be very unpleasant in high concentrations.
