3System Features
3.1 General
The Aquinity² system is designed for the production of analytical grade ultra pure water
from drinking water public municipal supply. The system combines the advantages of
reverse osmosis with final purification. Permeate from the reverse osmosis is temporarily
stored inside a tank. In a purification section ultra pure water with permanent highest
quality will be produced, supplied with the dispenser at the front side of the unit.
Currently recorded data and warning messages will be displayed on the system monitor.
All components of the system are assembled in a designed plastic housing. The housing
can easily be opened for the access of the modules. The system corresponds to the latest
technology and to recent safety regulations. It can be installed and put into operation
without the help of customer service.

When the system starts in normal operation mode, the inlet valve opens and the reverse
osmosis pump starts. It will be closed and the pump will be stopped, when the permeate
tank is completely full.
The pretreatment module ProPak-R10 is a combination of filtration and adsorption via
highly pure activated carbon. Chemicals like chlorides, insecticides, pesticides, and
herbicides and particles larger than 5 micrometer are detained.
The RO pump increases the pressure for the reverse osmosis process. The reverse osmosis
module remove about 98% of the salt content from the water. Moreover nearly all bacteria,
viruses, heavy metal complexes as well as organic molecules with a molecular weight
higher than 300 daltons are rejected. The purified water is called permeate, the waste reject
water is called concentrate. The concentrate water is rejected to drain via flow limiter.
The conditioning module is filled with ion exchanger resin. This module removes hardness
ions from the water to protect the EDI cell.
The permeate 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 and
the permeate will be drained.
3.4.1 EDI-cell in Aquinity² E
The EDI cell removes salt contents from the water by the principle of electro-deionization.
Ions pass a membrane into a concentrate chamber and are rinsed out by a flushing stream
(see Figure 3: schematic diagram of the EDI cell). The purified water is called electro-
deionized water. The EDI-electro-deionized permeate containing accumulated ions led to
drain is called sole.
The conductivity of this EDI-deionized permeate is monitored with a sensor. The measured
value is displayed in the unit µS/cm. If the conductivity exceeds a preset limit, a warning
message will be displayed and the solenoid valve will be closed. The solenoid valve will be
opened and the EDI-deionized permeate flows to drain.
The system must be connected to a tank with level control to regulate the production and
tank filling. When the tank is completely full, the production will be stopped. When the level
falls below 75%, the production will be started again and the tank will be filled. If the level
falls below the minimum filling of 15%, the circulation pump will be stopped to prevent its
running dry.

Figure 3: schematic diagram of the EDI cell
The conductivity will be decreased by an electro-chemical process within the EDI cell. The
ion exchange chamber provide for a salt removal from the water. Concentrate will be
drained. The conductivity value of the ultra pure water will be lower than 0.1 µS/cm.
3.4.2 Conditioning Module in Aquinity² P
The conditioning module is filled with mixed-bed ion exchanger resin. It is used to reduce
the salt concentration of the permeate in order to produce deionized water.
The conductivity of this deionized water is monitored with a sensor and displayed on the
system monitor in order to check the functionality of the conditioning module. If the
conductivity exceeds a preset limit, a warning message will be displayed and the
conditioning module should be changed.
The system must be connected to a tank with level control to regulate the production and
tank filling. When the tank is completely full, the production will be stopped. When the level
falls below 75%, the production will be started again and the tank will be filled. If the level
falls below the minimum filling of 15%, the circulation pump will be stopped to prevent its
running dry.
3.4.3 Purification elements in Aquinity² E and Aquinity² P
The UV submersible lamp inside the tank protects the stored water against microbial
contamination by direct UV radiation.

The tank will be vented with sterile air via CO2trap 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.

3.5 TOC monitoring (TOC systems only)
By measuring the oxidized material with subsequent electronic evaluation, it is possible to

3.6 Hardware
3.6.1 Dispenser
Figure 6: Standard dispenser
The dispenser has a lock function to make water tapping easier. Moreover, the dispenser
will stay in a fixed position which has increased its flexibility (no draw back function) and
gives the user more comfort when tapping water. This has been set as a standard
dispenser for pure water system and memtap system (optional).
3.6.2 Control PCB
Water system has a control pcb which provides communication between main computer
system and analog- & digital-sensors. This pcb has been flashed with a firmware (Firmware-
Version 0.13.8) with a watchdog function. If there is any problem with sensor reads, this
control pcb will restart the system automatically after ca. 2 minutes
