Introduction

This system uses potable tap water as feed and produces pure (Type 2) delivered by 1 or 2
independent E-POD
®
unit(s).
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 efciently removed before the reverse osmosis purication.
The intelligent reverse osmosis (RO) purication that controls water consumption, ensures a
constant product ow rate and optimal water quality. A large percentage 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 electrodeionization (EDI) 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 (type
2) water then stored in the storage tank.
Storage and distribution: Pure water is stored in high-quality polyethylene tank, which is equipped
with a vent lter and the mercury-free ech
2
o
®
automated sanitization module (ASM) lamp. The
tank vent lter maintains the consistent purity of stored water and provides effective 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. Throughout the distribution, resistivity,
temperature and pressure are monitored. Tank is congured with 2 or 5 meters connectors to
the main production unit depending on the laboratory setting.
The E-POD
®
(s) unit(s) is/are the main interface(s) 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/down, right/left and can be unhooked to
adapt to laboratory glassware. Its dispensing ‘wheel’ delivers water from low ow up to 2 L/min
owrate. The E-POD
®
unit large 5” touchscreen offers 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 (recommended).
When not in active use, the water within the units will recirculate for three minutes every hour.
This is to maintain water quality and to avoid contamination. The system should not be turned
off as this will stop the periodic recirculation taking place.
