Purified water

PURIFIED WATER

Compliance with international pharmacopoeias and beyond

Purified water is the essential raw material for pharmaceutical and cosmetic products. It is subject to strict regulations in accordance with the Ph. Eur. and USP international pharmacopoeias, which are imposed in the pharmaceutical industry and followed in the cosmetics industry out of concern for quality.

However, manufacturers, particularly in the pharmaceutical industry, tend to set themselves stricter limits than those imposed by the regulations. They therefore need to find solutions that will enable them to produce to high standards on a large scale.

 

Production, storage and distribution

Acqua Purificata must meet very precise fixed thresholds in terms of microbial load (including the absence of endotoxins), conductivity and organic carbon content. Producing purified water to these standards on an industrial scale, and storing and distributing it, without compromising its quality throughout the cycle, requires compact systems that combine mastery of processes, technologies and cutting-edge expertise.

In addition, choosing a water quality that exceeds the threshold values guarantees a margin between the quality produced and the alarm and action limits at the point of use, with no potential risk of an "out of specification" (OOS) incident
