NTRODUCTION TO THE SYSTEM

3.1

NTRODUCTION

The water purifier system «O maxi+» produces water of Class 2 as defined in ISO 3696 standard, which is
intended to be used by clinical analyzers.

The principle of purification uses two technologies:

the REVERSE OSMOSIS, which is currently the most effective membrane separation process,

the demineralization by ion exchange resin.

These two associated technologies allow getting water with excellent quality regarding physical composition,
chemical composition (mineral and organic) and micro-organic population.
