Biotechnological industry demand water of top quality, to meet 
standards increasingly restrictive. Trough more than 3 years, 
CIGB's Production Plant has been successfully employing the 
combination of water deionization followed by ozonation to obtain 
purified water for its productions, which consistently has met 
USPXXIII physico-chemical and microbiological regulations. Low 
doses of ozone have been found to be enough to fulfill the 
requirements and to guarantee the quality of the productions.
