The way out of the water crisis

Aquahara’s mission is to develop cost-effective, environmentally friendly and decentralized water supply systems in all regions of the world that suffer from water-shortage.

Whilst seawater desalination is considered an effective source of water, it is only available along coast-lines. Additionally, desalination systems consume high amounts of fossil-fuel and are prone to causing environmental damage.

An alternative has been the extraction of water from the air by cooling and condensation. However, this method consumes a lot of energy and is too expensive for a large-scale supply.

Aquahara has developed a much cheaper process for extracting and harvesting water from the air. Our alternative to electricity is solar heat and instead of condensation we use salt to extract water from air humidity.

We make water from air affordable.


How does it work?

It is commonly known from everyday life that salt absorbs moisture. For example, salt in the salt shaker gets wet and sticky, or applying to a spill on a tablecloth can help remove the stain.


We have adapted this phenomenon to absorb water from the air in order to extract clean fresh water.

Some types of salt attract so much water that they not only stick but become liquid. The salt solution is heated in a distillation unit with solar energy and releases the water in the form of steam again. The steam is cooled and condensed to clean fresh water.

Aquahara Technology GmbH has significantly reduced the costs of this process through technical improvements and developments.

The first of our patent applications already has a positive search report.

Humidity from the air is absorbed in a honeycomb structure (in the back/middle of the image), which is wetted with a concentrated salt solution.
In an evaporation column (in the front/middle of the image), the salt solution is evaporated using solar heat.
Pure water is condensed (approx.
3 liters per day per m2 of solar panel).

How to solve the global water crises?

There are various methods for producing clean drinking water.

1. The predominant method in offshore regions is building increasingly deeper wells and to use more complex purification methods to clean already existing but poor water resources.

2. The capacity of seawater desalination plants increases annually by approximately 7 million m3 of fresh water per day. Although this shows the huge increase in demand, seawater desalination is no option from 150 km inland.

3. Atmospheric water generators, which condense water from the air with the aid of an air-conditioning system. This way of extracting water from air still is extremely expensive, due to the high power consumption involved.

Why is Aquahara technology being developed now?

The process for absorbing moisture from the air in salt is known from dehumidification. It is used both industrially and in the household to dry the air in moist rooms with granules.

Since salt has a very corrosive effect, very expensive materials such as titanium had to be used in industrial plants.

For the first time, Aquahara’s patent pending process improvements and the availability of new materials will cut production costs dramatically.





How can you draw water from extremely dry desert air?

Even very dry desert air still contains 7 ml of water per cubic meter of air. The process developed by Aquahara extracts about 1 ml of water per cubic meter of air. If you want to extract a glass of water, you need about 200 cubic meters of air. This is approximately the equivalent air mass of a small breeze flowing around our bodies over 2 minutes.

How much water is produced what does it cost?

20 x 20 meters (66 feet x 66 feet) of solar panels can produce 1,000 liters (264 gallons) of water per day.

Current atmospheric water generators currently produce water at a cost of about 0.05 € per liter, that is about 50, – € per m3.

With our technology we aim to reduce these costs by 80 to 90% and our first tests indicate that we can reach this very competitive cost level. 

When will the test facility be seen?

All technical components of the technological process are currently being tested in a test facility. By the end of 2018, systematic tests will be performed on the functional sample.
