Hanovia ensures safety of purified water for production in China’s National Vacine Production Base

Three UV water disinfection systems supplied by Hanovia to the Institute of Medical Biology of the Chinese Academy of Sciences in Kunming destroy any unwanted microorganism in the purified water used in the production of vaccines.

Shen Feng, senior engineer and water treatment equipment expert at the Institute, said: “Hanovia’s PharmaLine PQL offers validated disinfection that has been certified by an independent third party. It also displays the UV dose online, meeting the stringent requirements of the pharmaceutical industry for verification and risk management.”

Purified Water is an essential raw material for the production of vaccines and indicators (TOC, bacterial endotoxins, microorganisms, pH and conductivity) are strictly required in the pharmacopeia of many countries. Of these indicators, all but microorganisms and bacterial endotoxins can be controlled by water preparation technology.

UV kills 99.9% of the microorganisms, ensuring the concentration in purified water remains at an extremely low level (≤5cfu/ml). UV also does not produce any unwanted disinfection by-products that might contaminate the purified water downstream.
