The reverse osmosis (RO) process is used in many industries. This process uses membrane separation which has been proven to be one of the most economical means to remove suspended solids from feed water.
Ultrapure Water (UPW), Water for Injection (WFI), High-purity Water and Deionized (DI) are all terms describing basically the same property. They refer to water which has been purified to the highest standards by removing all contaminants such as organic and inorganic compounds; dissolved and particulate matter; volatile and non-volatile, reactive and inert; hydrophilic and hydrophobic; and dissolved gases. The purified water has very low conductivity which means it is high in resistance because all the conductive components have been removed. Combined with susceptibility to contamination and temperature effects, low-conductive solutions make accurate pH measurement very difficult to achieve. Achieving accurate and reliable readings using a traditional pH analyzer is challenging. However, by understanding what causes the difficulties in pH measurements and having the proper equipment, stable and accurate pure water pH measurement can be accomplished.
