General Information

The Milli-Q system is used as a final water purification stage. The feedwater to a Milli-Q can be produced
by electrodeionisation (E.D.I.), Reverse Osmosis (RO), distillation or deionisation.
The Milli-Q system produces water of Type 1 quality. This is equal to or better than ASTM, CAP and NCCLS
Type 1 water quality standards.
The principal components of the Milli-Q system, Figure 1, are:

How the system works

Pre-treated water (from E.D.I., Reverse Osmosis, distillation or deionisation) enters the system and is pumped
through the Q-Gard cartridge for an initial purification step.
The water is then exposed to UV light at both 185 and 254 nm wavelengths. This oxidises organic com-
pounds and kills bacteria.
The function of the Quantum cartridge is to remove trace ions and oxidation by-products produced by the
action of the UV light.
Purified water then passes through an Ultrafiltration (UF) module. The UF module acts as a barrier to
colloids, particles and organic molecules with a molecular weight greater than 5000 Daltons. The contami-
nants retained by the UF are periodically flushed out of the system via tubing to a drain.
A manual 3 way valve located in the point of use (POU) allows you to direct ultrapure water through a final
filter made up of a 0.22 µm membrane (MilliPak-40). The final filter removes particles and bacteria greater
than 0.22 µm in size and prevents recontamination of the system from the point of use.
The A10 TOC monitor takes samples of ultrapure water to determine trace organic levels. Samples are
taken periodically in PRODUCT mode.
