The European Commission of Drug and Medicine has made two classifications for water quality.
“Water for injection purpose” and “water for industrial purpose“.
The germ number for “water for industrial purpose” should be below 10 cfu/100ml, probe and conductivity below 5 µS/cm. In order to receive proper validation requirements by the pharmaceutical industry can individually differ.
After deionisation ultra filtration is a possibility to receive bacteria and pyrogen-free (BGF) water. In order to avoid any bacteria growth or bio-slime inside of the distribution a loop ozone has to be used continuously. Bio film can be controlled by coupons installed in the circuit.
For safeguarding biological contamination in the DIW loop it is important to have dissolved ozone available, wherever and whenever. Discover our ultra-pure treatments for your specific application.
