EWA
Extraction of Water from Air
The EWAIII produces
clean, pure water
by extracting h2o molecules
from the atmosphere.

The Goals:
• To access a new, unlimited, renewable
source of water.
• To create an endless supply of clean
water at nearly any location in the world.
• To provide this water in an energy efficient,
environmentally friendly way
and at a relatively low cost.

The Answer:
EWAIII
A machine that produces
clean, pure water
by extracting h2o molecules
from the atmosphere.

EWAIII
You can have the
convenience of
industrial quantities of
fresh, pure water
at your location,
even in the desert.
In fact, anywhere!

Unique Technology
The EWAIII uses
ground-breaking new technology
to run efficiently and economically,
whilst using very little energy.
How much water can be
extracted from the air?
There are approximately
40,000 cubic metres of water
in one square kilometre of air
& it is constantly renewable.

The Technology
EWA Technology involves three complementary processes:
1. Adsorption of water from the air on solid desiccant.
2. Desorption of the absorbed water.
3. Water condensation and quality adjustment.
Condensation
Vapor adsorption
Water desorption

Modular Design
EWAIII is designed as a modular system,
starting with the EWAIII20,
that produces 10,000 litres of water daily.
More machines may be added,
More machines may be added,
to produce up to
1,000,000 litres of water daily.

Energy Used
The EWAIII uses only
10 kW-h of electricity and
25,000 Kcal of energy
to produce 1,000 litres of water.
Any form of energy can be used,
including any kind of residual heat.

Installation
The EWAIII is self-contained,
the size of a standard shipping container.
It can be transported to the site and
positioned on any flat surface.
The only installation required
is the coupling of the energy source,
the heater and the EWAIII unit.

Operation & Maintenance
EWAIII machines are fully automatic.
Air filtration is not required,
though the water produced is
totally fresh and pure.
The desiccant does not absorb
any air pollution.
Regular maintenance is minimal.

The Environment
The EWAIII will operate
in any environment,
where the temperature ranges
from 5° to 45° Celsius
and
with a minimum of
20% relative humidity.

Environmental Impact
This technology has
no environmental impact.
It is at least carbon neutral
& it may produce carbon credits
(depending on which energy is used).
It does not produce
any waste or residue.

Industry Potential
EWAIII machines have great potential
in water intensive industries,
where (traditional) natural water sources
are not readily available.
They can be installed anywhere and
do not need any piping or pumping.
