PRODUCTION OF ULTRAPURE WATER FOR PHARMACEUTICAL AND MEDICAL APPLICATION: ROLE OF REVERSE OSMOSIS
Keywords:
reverse osmosis, ultrapure water, permeability, pharmacy, medicineAbstract
The membrane processes are a very important part of chemical and water treatment technology that is used in a broad range of applications. The most important aspect of the process is the ability to control the permeation rate of different water constituents through the membrane. In the frame of this work the reverse osmosis (R.O.) technology and its application in pharmaceutical and medical industry has been analysed. The water treatment systems used in pharmacy can be different depending off the final user and water application, nevertheless the process design starts with feed water treatment. Because of this, to prepare the raw feed water for the treatment systems, the water treatment includes several preliminary steps as chlorination, de-chlorination, activated carbon filtration, ultrafiltration, water softening and chemical compounds addition. For further water purification the contemporary green processes include reverse osmosis as a technology for preparing water for pharmaceutical and medical applications. The major impact on the design of the R.O. processes has the required capacity of the purified water.
