3 VOLTEA CAPDI - MEMBRANE CAPACITIVE DEIONIZATION

The CapDI system uses Capacitive Deionization technology and its function is the removal of ions from the water.

NOTE: The CapDI system does not disinfect water.

CapDI: A tunable water deionization technology that is designed to remove dissolved salts from a variety of

water sources ranging from tap water and brackish groundwater to industrial process water. CapDI achieves this at a lower economic cost and reduced environmental impact than any other available technology.

Page 7

A CapDI module consists of a housing which contains multiple stacks of parallel unit cells. Each unit cell consists of two porous carbon electrodes separated from each other by a spacer. On top of the electrodes, ion exchange membranes are placed. The spacer between the membranes acts as a flow channel to transport the water to be desalinated.

The water flows through a small electrical field of approximately 1.5 volts that is created over a pair of electrodes. Dissolved ions are pulled out of the water stream, toward the electrodes. The electrodes are separated from the water by the membranes that selectively allow only positive or negative ions to pass. CapDI is effective at removing all type of ions from water (e.g. calcium, sodium, chloride, carbonate).

Uniquely: Our technology is environmentally friendly by its low energy consumption and minimal to no chemical usage. Thus, allowing any unrecovered water to flow back into the ecosystem safely.

Scalable: Voltea’s technology treats water types ranging from residential consumer appliances to large-scale industrial plants. Our systems are modular, allowing easy expansion to meet any increased water demands.

Tunable: CapDI is tunable, allowing adjustable TDS reduction between 25% - 95% depending on customer needs. Eliminating the requirements for blending to achieve a specific water quality. The customer sets their desired reduction rate and the CapDI maintains this level, continually adjusting itself to account for any fluctuations in feed water characteristics.

4 DIUSE

Voltea’s miniaturized version of the CapDI systems, specifically made for the point-of-use applications. DiUse softens and desalinates brackish water for homes and businesses at an advantage to traditional desalination technologies due to it being a salt-free, chemical-free alternative. DiUse is ideal for the HoReCa industry alongside small households.

10 CHANGING FLOW RESTRICTORS

• DiUse is shipped with 2.15 l/m (0.56 gpm) flow

restrictor in High flow line and 0.9 l/m ( 0.23 gpm) flow restrictor in Low flow line.

• DiUse is shipped with 5 spare flow restrictors of

different colors and flows, for more information refer to appendix.

• To remove the connections holding the flow

restrictors in place, use a flathead screwdriver to hold the latching mechanism in place, whilst rotating the black fitting counter-clockwise by 90 degrees.

• This will unlock the fitting which can then me

removed by pulling away from the assembly.

• Once the fittings are removed, use a small

flathead screwdriver to lever out the flow restrictor, being careful not to damage the central mechanism.

• Replace these flow restrictors with the desired

ones. First remove the old flow restrictor from the flow restrictor housing by gently pushing with a screwdriver. Then insert the desired flow restrictor by reversing the procedure described above.

• Push the black fittings back onto the valve

assembly rotating them 90 degrees clockwise to lock in position.

NOTE: Flow restrictor change is only advised after consulting Voltea.

Flow restrictors

Page 33

• On the LCD, update the Pure Flow Target set point

in Systems/Set Points. This value is only in liters per minute (L/min). If adding an X l/m flow restrictor in the High flow and a Y l/m flow restrictor in Low flow, set the pump to X plus Y minus 0.2, i.e. if you add a 2 l/min flow restrictor in the high flow and 0.9 l/m flow restrictor in the low flow, set the pump to 2.7 l/min.

• After flow restrictor replacement the low flow

pure and low flow waste alarm setpoints need to be updated. The new value should be the low flow restrictor value divided by 2 for waste and the sum of the two flow restrictors values divided by 2 for pure. More about setpoints in section 8.4.1

11 ELECTRICAL CONDUCTIVITY PROBE CALIBRATION

Equipment needed:

• Temperature probe (capable of reading atmospheric temperature)

• Calibration solution, Voltea recommends 147 μS/cm standard solution.

• Phillips screwdriver.

• External EC probe.

• External mounted EC probe.

To calibrate the electrical (EC) probe, do the following:

• Remove the flat covers

• Open the cabinet door

• Disconnect the EC probe connections

from the PCB

Page 34

• Connect the external EC probe on the

PCB.

• Rinse the EC probe with demineralized

water and dry with paper.

• Power on the system

Conductivity probe is calibrated through Docklight. Before EC calibration, temperature has to be calibrated. For more information on how to use Docklight please refer to chapter 9.2.1. Open the program and perform the following by pressing the Send button.

Temperature calibration:

• Click - Temp module active to activate

the probe.

• Click - Get Temp^ Mod Calibration.

12 FLUSHING, BLEACHING, STORING AND MODULE DISPOSAL

12.1 FLUSHING THE MODULE

Flushing the module is required for at least 15-20 minutes before starting operation for the first time. To flush the module, select the built in function via the LCD screen.

12.2 BLEACHING THE MODULE

Bleaching the module before storing is highly recemented. To bleach the module a 120-ppm free chlorine solution is needed. Non-scented household bleach can serve as the free chlorine source. The free chlorine concentration in a typical household bleach product is 8.5%, in this case dilute by adding 1.4mL of bleach into the 1L of water.

Fill the CIP container with the 120-ppm free chlorine solution. Through the main controls go to RELAY TEST and open the CIP Pump (CIP) and Waste valve (WOV). This will allow the chlorine solution to insert the module and be discharged through waste line. Close both when the CIP container is empty.

12.3 STORAGE

In case of module long term storage (>3 days), it is advised that after the last period of operation and before the long break, an aqueous solution containing 30g/L NaCl, 2g/L glycolic acid and 1g/L Sodium Benzoate is flushed through the module for 5 minutes. After flushing the module should be sealed with the orange stoppers.

NOTE: Clean or sterile water should be used for the storage solution.

If the period of no operation is longer than 1 month, the storage solution should be replaced every month.

Page 38

An alternative solution with a longer storage period using a bio-growth inhibitor is available, please contact Voltea for more information.

12.4 DISPOSAL

When (parts of) the DiUse has reached the end of its serviceable life time the following must be observed before disposing:

• Some parts may be reused so please contact Voltea before disposing DiUse.

• The system should be discharged in accordance with legislation in force locally.

• Materials should be reused or disposed in an environmentally friendly manner.

• Throughout operation and depending on the application a CapDI module may have been exposed to

and may have accumulated harmful components. The user is responsible for proper disposal in accordance with local legislation.

13 SYSTEM MAINTENANCE

To ensure continuous and untroublesome operation, Voltea suggests a weekly check. You can find the weekly check form in the Appendix.

Pure electrical conductivity, the alarm list and the CIP solution level is advised to be checked weekly.

Fan filter and the check valves in the manifold should be checked at least every 6 months.
