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.
