B Basic information
1 | Laws, regulations, standards
In the interest of good health, rules cannot be ignored when it
comes to the processing of drinking water. This operation
manual takes into consideration the current guidelines and
stipulates information that you will need for the safe operation of
your water treatment system.
Among other things, the set of rules stipulate that
 only approved specialist companies are permitted to make
major modifications to water supply systems
 and that tests, inspections and maintenance on installed
devices are to be performed at regular intervals.
2 | Water
As a result of dynamic substance and water cycles, increasingly
polluting elements are being released into the natural
environment. These are only partially and slowly broken down by
natural effects. Consequently, these elements build up in the
groundwater and surface water over the course of time.
Removing them from natural water deposits again represents a
particular challenge. Grünbeck faces this challenge with the
aim of producing unpolluted drinking and industrial water.

3 | Functional principle of electrodeionisation
3.1 Functional principle of electrodeionisation
Function The electrodeionisation represents a continuous, electrochemical
membrane process that combines membrane technology and ion
exchanger technology.
In this process, ion exchanger resin, ion-selective membranes
and direct current are used to remove ions from the permeate of
a reverse osmosis system.
The resulting diluate (ultra-pure water) has a residual
conductivity of < 0.2 µS/cm. The residual conductivity depends
on the quality of the feed water (permeate).
The advantage of this technology is the fact that the
regeneration (by means of direct current) continuously takes
place during operation and no chemicals (acids/bases) are
required.
Contrary to common ion exchanger systems, the
electrodeionisation system GENO-EDI-X considerably
reduces the TOC values.
The core – the EDI module – consists of several chambers filled
with layers of anion and cation exchanger resins. The chambers
are separated from each other by anion and cation membranes.
The feed water (permeate) flows into the EDI module and is
divided into a diluate, concentrate and electrolyte water flow.
Due to the direct voltage applied, the ions move from the
diluate chambers filled with ion exchanger resin to the
concentrate chambers that are also filled with ion exchanger
resin.
While the water is in the diluate chambers is being fully
demineralised, the direct current splits the water into hydrogen
ions (H+) and hydroxide ions (OH-) by which in turn the ion
exchanger resins are regenerated again.
A part (10 %) of the feed water volume (permeate) rinses the
concentrate and the electrode chambers. The volume
designated as concentrate (unpressurised) is then either
directed to the drain or returned to the inlet of the reverse
osmosis system to be fed again.
The electrodeionisation system GENO-EDI-X has a recovery of
90 - 95 %.

3 | Basic function of the electrodeionisation system GENO-EDI-X
(without options)
If the system is in standby mode and ready for operation, the
inlet rejection valve and the inlet valve are closed. There is no
voltage present at the EDI module. If available, the outlet
rejection valve is open and the outlet valve closed. The
electrodeionisation system receives its start signal from the level
control system of the diluate tank. Then, the EDI controller
transmits the start signal to the RO controller. The RO system
starts operation and produces permeate. By means of the inlet
rejection valve, the time-controlled discharge of the permeate to
the drain takes place. In case the conductivity measuring cell for
permeate is installed, the rejection can be terminated prema-
turely if the max. permeate conductivity set is undershot.
Upon termination of the inlet rejection, the inlet valve opens and
the inlet rejection valve closes. When the inlet valve opens, the
EDI cell is supplied with voltage. From the moment the inlet
valve opens, the flows diluate and concentrate, the diluate
conductivity, the pressure of permeate, diluate and concentrate
as well as the temperature and the diluate are monitored and
trigger a time-delayed (adjustable) warning or an alarm. The
diluate is rejected via time by means of the outlet rejection - if
available (option) -, with premature termination in case the max.
diluate conductivity set is undershot. Following the opening of
the outlet valve, the outlet rejection valve is closed. The diluate
produced is now directed to the diluate tank.
As soon as the tank is full, a stop signal is transmitted to the EDI
controller. Within the electrodeionisation system, the voltage
supplied to the EDI cell is interrupted and the monitoring function
of the EDI system is deactivated. After a set rinsing sequence,
the RO system receives its stop signal and the valves move to
the following positions: Inlet rejection valve and inlet valve close
and – if available – the outlet rejection valve is open and the out-
let vale is closed. Now, the electrodeionisation system remains
in standby mode until the next demand is made.
If the system is in standby mode, the inlet rejection valve Y8 and
the inlet valve Y7 are closed. There is no voltage present at the
EDI module.
The GENO-EDI-X system receives a start signal from the level
control system of the diluate tank. Then, the EDI controller trans-
mits the start signal to the RO controller.
The RO system starts operation and produces permeate. By
means of the inlet rejection valve Y8, the discharge of the per-
meate to the drain takes place over a pre-set time period. Upon
termination of the inlet rejection, the inlet valve Y7 opens and the
inlet rejection valve Y8 closes.
When the inlet valve Y7 opens, the EDI module is supplied with
the divided partial permeate flows of diluate and concentrate.
In addition, the voltage and current are switched to the EDI mod-
ule.

From the moment the inlet valve Y7 opens, the diluate F7 and
concentrate F8 flows, the diluate conductivity Q5, the pressure
of permeate P4, diluate P5 and concentrate P6, as well as the
temperature of the diluate T2 are monitored and trigger a time-
delayed (adjustable) warning and/or an error.
The diluate produced is now directed to the diluate tank. As soon
as the tank is full, a stop signal is transmitted to the EDI con-
troler. Within the GENO-EDI-X electrodeionisation system, the
voltage supplied to the EDI cell is interrupted and the monitoring
function of the GENO-EDI-X system is deactivated.
After a set rinsing sequence, the RO system receives its stop
signal and the valves move to the following positions: inlet rejec-
tion valve Y8 and inlet valve Y7 closed.
Now, the GENO-EDI-X system remains in standby mode until
the next request is made.

6 | Intended use
The electrodeionisation system GENO-EDI-X is designed for the
further quality enhancement of permeate generated by a
reverse osmosis system.
The most common areas of application for the diluate produced
(ultra-pure water) are:
- Steam sterilisation
- Semi-conductor industry
- Generation of pure steam
- Laboratories
The system can be used only after a prior water analysis and
corresponding pretreatment.
The continuous diluate output of the system is subject to the
temperature and is defined at 15°C. The diluate outputs can fall
(falling temperature) or rise (rising temperature) by up to 3 % for
each °C the raw water temperature increases or decreases.
Only operate the system if all components are properly installed.
Safety devices must NEVER be removed, bridged or otherwise
tampered with.
Appropriate application of the device also implies that the
information contained in this operation manual and all safety
regulations applying at the installation site be observed.
Furthermore, the maintenance and inspection intervals have to
be observed.
6.1 | System shutdown
During decommissioning of the GENO-EDI-X system, the
necessary measures must be decided upon together with
Grünbeck’s technical service.
