In the production of medicines, various auxiliaries and the process medium, in particular water, are widely used. Water for medical production is divided into 2 parts: purified water and WFI (water for injection). Purified water is obtained after carrying out a two-stage reverse osmosis and passing through the water demineralization system (demineralization), used for biochemical products, cleaning medical equipment, etc.

WFI (water for injection) after the distiller is used to produce injectable drugs.
