Membrane Degasification: Chemical-Free Alternative for the Pharmaceutical Industry
In treating water for the production of pharmaceuticals, the concentration of gases dissolved in the water plays an important role. In many cases the CO2 content in the raw water has to be further reduced to obtain purified water with a conductivity of < 1.3 μS/cm (at a temperature of 25°C).
Historically, NaOH dosing has been used to control CO2. With chemical dosing CO2 is converted into a carbonate, which can be removed by the RO. The latest state-of-the-art technology for this task is membrane degasification where chemicals are not needed.
