Introduction

This system uses potable tap water as feed and produces pure (Type 2) and ultrapure water
(Type 1) delivered by independent POD dispensers.
The system is divided into three sections. These are the production, the storage and the
distribution.
Production: Tap water is rst puried by the IPAK Gard
®
pretreatment pack
which contains the pleated lter and carbon block. Particles, colloids and
free chlorine are eciently removed before the reverse osmosis purication.
The intelligent reverse osmosis (RO) purication that follows controls water consumption,
ensures a constant product ow rate and optimal water quality. Majority of contaminants are
removed at this stage such as the ions, particles, bacteria and large organics. The puried RO
water then enters the patented Elix
®
electrodeionization module, where ion-exchange resins are
continuously regenerated by a small electrical eld. The pure water then passes through the
mercury-free ech
2
o bactericidal lamp where bacteria is further eliminated resulting in pure water
that is stored in the storage tank.
Distribution: Pure water is stored in high-quality polyethylene tank, which is equipped with the
vent lter and the mercury-free ech
2
o ASM lamp. The vent lter maintains the consistent purity
of stored water and provides eective protection against airborne contaminants. The ech
2
o ASM
lamp further protects the integrity of the stored water with regular exposure to bactericidal UV
light. Puried water then ows to the mercury-free ech
2
o oxidation lamp. Organic molecules
are partially oxidized, resulting in ions. These are then captured in the next stage when the
puried water enters the IPAK Quanta polishing cartridge, composed of ion-exchange resins and
synthetic activated carbon.
Throughout the purication steps, quality parameters are monitored with resistivity sensors and
the A10
®
TOC (total oxidizable carbon) monitor. The A10 TOC Monitor uses a small UV lamp
during its TOC analysis mode. This is called the ech
2
o A10 TOC Lamp.
The E-POD and Q-POD are the main interfaces with the user. They are congured with 2 or 5
meter connectors to the main production unit depending on the laboratory setting. The arm
holding the dispenser on the mast can be moved up and down to adapt to laboratory glassware.
Its dispensing ‘wheel’ delivers water from precise drop-by-drop up to fast 2 L/min owrate. The
POD’s large 5” touchscreen oers a wide range of applications for users. It also has an USB port
to easily export data. At the outlet of the dispenser, the nal purication is performed by the
application-specic POD-Pak.
When not in active use, the water within the units will recirculate for three minutes every hour.
This is to maintain water quality, a clean environment and to avoid contamination. The system
should not be turned o as this will stop the periodic recirculation taking place.
