The tank will be vented with sterile air via CO
2
trap ventilation filter.
Stored permeate can be drawn off via tap valve at the front of the tank.
With respect to safety, a float switch is provided. This protects the tank from overflowing
liquid levels.
The circulation pump feeds the water into the polishing section with circulation.
UV systems only:
Inside the UV reactor free hydroxyl radicals (OH
-
) are produced. These
radicals oxidize remaining organic materials in the water.
TOC systems only:
The TOC concentration is monitored with a sensor and will be displayed
on the system screen as TOC.
The polisher module UPW-Pak Art.-No.: 190-0087 is filled with high grade mixed bed resins
in semiconductor quality to reduce mainly the salt content. For inorganic applications
which do not require a low level TOC the polisher module UPW-Pak Art.-No.: 190-0088 can
be used.
UF systems only:
The ultrafiltration module removes endotoxins and viruses from the water.
Ultrafiltrated water is almost free of RNase, DNase and DNA. If water will be taped, the
module will automatically be flushed via flushing valve.
Product water conductivity is monitored with a sensor and displayed on the system
monitor. If the conductivity exceeds a preset limit, a warning message will be displayed.
A sensor monitors the temperature of the product water. If the temperature exceeds the
limit of 40°C, a warning message will be displayed.
The sterile filter protects the system against microbial contamination by filtration of
particles larger than 0.2 µm.
Product water will be supplied via dispenser. For a small volume of product water the
dispenser button has to be pressed slightly, for a higher volume the dispenser can be
switched into permanent position.
A check valve keeps the circulation pressure constant and prevents a backflow of the
product water.
