Description of the system
The Milli-Q
®
EQ 7000 manages the production and the distribution of ultrapure water from a
purified water source such as a tank or a pressurized loop. It consists of three main units:
• The water purification unit manages the production of ultrapure water.
• The Q-POD unit manages the dispensing with Quick info for the performance of the system
through LEDs.
• The HMI unit provides the user interface
.
Purified water either from a pressurized loop or a storage tank enters the purification unit.
It is first purified by the IPAK Meta
®
polishing cartridge composed of ion-exchange resins,
removing the bulk of the ions. The purified water then flows to the UV 185nm oxidation lamp.
Organic molecules are partially oxidized, resulting in ions. These can then be captured in the
next stage when the purified water enters the IPAK Quanta
®
polishing cartridge, composed of
ion-exchange resins and synthetic activated carbon. The IPAK Meta and IPAK Quanta polishing
cartridges always need to be replaced together to ensure optimal purification down to trace
levels of contaminants. Throughout the purification steps, quality parameters are monitored
with resistivity and temperature sensors and the TOC (total oxidizable carbon) indicator. The
TOC indicator gives an indication of the total organic content measured in ppb at the point of
distribution.
