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.

Electrodeionisation System

GENO-EDI-X

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 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 prematurely 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 outlet 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 transmits 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 permeate 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 module.

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 timedelayed (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 controler. 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 rejection valve Y8 and inlet valve Y7 closed.

Now, the GENO-EDI-X system remains in standby mode until the next request is made.

Electrodeionisation System

GENO-EDI-X

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.

H Maintenance

1 | Basic information

In order to guarantee the reliable function of the systems over a

long period of time, some maintenance work has to be performed at regular intervals. All regulations and guidelines which apply at the installation site must be strictly adhered to.

 A daily check of the quality and the system volume flows

must be performed.

 The log sheets must be filled out daily on warranty

grounds. Conclusions regarding any problems/damage can also be derived from these documents.

 Maintenance has to be performed by Grünbeck’s

technical service/authorised service company or by a specialised company. Maintenance is subject to the load, but at the latest has to be performed once a year.

 An operation log and the corresponding test log must be

kept in order to document the maintenance work performed.

Note: By concluding a maintenance contract you ensure that all



maintenance work will be performed in due time.

The maintenance work performed must be documented in the checklist, refer to appendix "Operation log".

2 | Inspection (functional check)

You may perform the daily inspections yourself.

Please refer to the following overview for the tasks to be performed within the scope of an inspection.



Overview: Inspection work

 Determine the feed water quality (inlet);

check any pretreatments.

 Check the diluate quality.

 Check the diluate flow volume.

 Check the concentrate flow volume.

 Check the current and voltage values.

 Check the pressures and differential pressure

(diluate/concentrate).

Note: Minor deviations are normal and cannot be prevented technically. In case of considerable deviations from the standard, notify Grünbeck's technical customer service.

 Check the seal tightness of the system.

 Check the electrical connections on the EDI module.

 Check the earthing connections on the EDI module (4 pieces).
