INTRODUCTION
General Information
The Autopure WR600 system is used as a final step of water purification. The feedwater to a Autopure WR600 system can come
from electrodeionisation (ELIX), Reverse Osmosis (RO), distillation or demineralisation.
The Milli-Q system produces water of Type 1 quality. This is equal to or better than ASTM, CAP and NCCLS water quality
standards.
The principal components of the Autopure
WR600, Figure 1, are:
(A) Control Panel
(B) Q-Gard pack adapter
(C) Q-Gard pack
(D) Door for installing / removing QUANTUM purification pack
(E) Liquid Crystal Display (LCD)
(F) LED Indicator
(G) Keypad
(H) ON / OFF Power Switch
(I) Power cord socket
(J) Fuse Holder
(K) Fittings / inserts for water connection
(L) Sanitisation port plug for cleaning the UF module
(M) Point of Use Gun with support arm
(N) Sticker with serial number, lot number and system type
(O) Screw for attachment piece
(P) Attachment piece to hold cover to system
How the system works
Pre-treated water (from EDI, Reverse Osmosis, distillation or demineralisation) enters the system and is pumped through the
Q-Gard pack for an initial purification step.
The water is then exposed to UV light at both 185 and 254 nm wavelengths which oxidises organic matter and kills bacteria.
The function of the QUANTUM cartridge is remove ions produced from 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 other
organic molecules with a molecular size higher then 5000 Daltons. The contaminants retained by the UF are periodically flushed
out of the system via tubing to a drain.
A manual 3 way valve directs ultrapure water through a final filter made up of a 0.22 um membrane (MilliPak-40). The final filter
prevents particles and bacteria greater than 0.22 um in size from being dispensed from the system.
The A-10 TOC monitor takes a sample of ultrapure water and determines the trace levels of organic material in it. The samples are
taken periodically in PRODUCT mode. Because of the sampling frequency, the displayed water quality is representative of an
instantaneous value.
