Merck Milli-Q EQ 7008 - Water Process

Introduction
5
Water process
The Milli-Q
®
EQ 7008/7016 water system manages the production and the distribution of ultrapure
(Type 1) and pure water from a tap water source. It is composed of three dierent sections:
• Water purication unit manages the production of ultrapure water. It produces and lls the storage
tank with RO quality water.
• Storage tank stores and maintains the RO water quality.
• Point of dispense (Q-POD
®
unit) manages the dispensing of ultrapure water. ‘Check and Dispense’
LEDs provide information about the performance of the system.
