Unique Technology
Inflow water passes through the cell Electrodes are layered into the cell A D.C current of 1.6V is applied across
the electrodes Individual electrodes are charged with
different polarities Minerals in the water are attracted to the
opposite polarity of electrode These minerals are electrochemically absorbed onto the electrode When sufficient minerals are absorbed onto the electrodes they are
released in a regeneration step Contaminants fall off the electrodes and flushed away for discharge or
reuse.

What is EcoAeon EWP®?
New technology bringing Hybrid Capacitive Deionization “HCDI” to life using the “Flow Capacitor” to desalinate aqueous solutions
Proven Technology
Offering sustainable water solutions in both developed countries and for the treatment of contaminated drinking water in developing countries.

About EcoAeon EWP® A new system that desalinates and purified water
without using ion exchange resins or membrane filters
Chemical Free
Using a direct low voltage current
Lowest energy consumption for purifying water
Requires no pre-treatment of water
Low maintenance

How does it work? In the working phase the
ions present in the water are attracted and retained by the electrode that is supplied with the opposite polarity
© EcoAeon 2010
How does it work? After removing a certain quantity of
contaminants (ions) the level of ions exiting the cell begins to increase, signifying that the EA EWP® cell is loaded
The working flow is interrupted, and the electrical supply to the electrodes is cut through a short circuit
The ions (contaminants )which were absorbed on the electrodes recombine after detaching from the electrodes

How does it work? The electrodes are supplied with
an opposite charge for a short amount of time (10-30 seconds)
A reduced flow flushes the concentrated salts in the cell for either disposal or re-use
Then the cycle starts again

Heavy Metals Chrome Iron Copper Silver Gold Zinc Nickel Cadmium Mercury Lead Manganese
Normal Salts Calcium Carbonate Magnesium Carbonate Sulfates Phosphates Sodium Chloride (salt) Chlorides Fluorides
Other Organics
( that dissolve ) Pathogens up to 99%
Biggest Problems Today Nitrates (99% removal) Arsenic (99% removal) Humic Acid (99% removal) Ammonia (99% removal) Chromium 6 (99% removal)

Energy Consumption
As an example, the energy consumption is in the order of 0.20-0.40 KWh per 1000 liters for a solution of 1000 mg/l of NaCl (salt)
A major advance in sustainable water treatment

Applications The EcoAeon EWP® techonology has infinite
applications We have divided them into three distinct types:
• Partial desalination
• Full Demineralization
• Special applications and treatment of waste water
© EcoAeon 2010
EcoAeon EWP® Single pass: Used when only partial desalination is required Used as an ion exchange water softener without
using salt Used for agricultural irrigation Used to remove Nitrates, Arsenic and organic
contaminants from drinking water
© EcoAeon 2010
EcoAeon EWP® Twin Pass: For demineralisation of water To obtain residual conductivity of less than 4 μS/cm A multiple pass unit to demineralise water with
high salt concentration (up to 10,000 mg/l of NaCl - Salt)
© EcoAeon 2010
EcoAeon EWP® Waste Water: For the reuse of water To reduce the salt concentration after chemical
precipitation plants To desalinate water after biological purification
plants in relation to their re-use and a possible replacements of membranes
To reduce investment and operational costs of a thermal distiller or of Reversal Osmosis unit
And for all the special applications
