Five examples of Water Collected from Air

Air to Water Five Examples



Water from Air is a new concept for the conservation of water by adopting a source that is uncommon and renewable. The most abundant source of freshwater is the Earth’s atmosphere. When atmospheric humidity condenses, it falls as rain. This natural process of condensation is replicated by adopting different technologies, which allows it to make water continuously, even in low humidity conditions.

Here are the examples :



1)Airowater Dewpoint Smart


"The Airowater Dewpoint Smart is one of the smaller units designed to ensure portability. This unit can make up to 20 litres per day in relative humidity and is also equipped to use city water as the input source to deal with a sudden increase in demand!"



2)Rainmaker


"Rainmaker’s Air-to-Water units produce drinking water from the air – no other water source is required. " It uses a turbine that forces air through a heat exchanger, where the air is cooled and condensation takes place. A hybrid solution (solar/wind/grid) is deployed for forcing the air into the heat exchanger. The temperature of the air is lowered in the exchanger to produce water drops which are collected in a container. Rainmaker Air-to-Water application, can "harvest water by combining atmospheric humidity, heat, and air flow producing 5,000, 10,000 or 20,000 liters per unit, per day."





3)Akvo AWGs


"The most abundant source of fresh water is the Earth’s atmosphere. When atmospheric humidity condenses, it falls as rain. Akvo® replicates this natural process of condensation by simulating the dew point, which allows it to make water continuously, even in low humidity conditions. Our unique technology uses optimized dehumidification techniques to extract and condense moisture in the air to produce healthy purified drinking water."




4) Watergen 

"Watergen is the pioneering Israeli company that has become the global leader in the atmospheric drinking water devices (AWG) market, machines that create drinking water from the air. The company’s solutions are the most effective and economical way to solve the pressing issue of drinking water scarcity in any location and at any time, and also enable the elimination of carbon-intensive supply chains and environmentally-harmful plastic waste.

Watergen’s products produce up to 5 liters of fresh drinking water by water extraction using 1 KWH. The company’s technology also facilitates significant water production in climates with humidity as low as 20%."




5)Watermaker 


"Atmospheric Water Generators (AWGs) in India, could provide clean and healthy drinking water amounting from 120 liters to 5000 litres per day. We also export these WaterMakers (AWGs) to many other countries,” says Meher."

Most of the air to water systems that are available in the market use the condensation of air phenomena. The atmospheric air is passed through freezing surfaces such that air moisture will be condensed and collected as water drops, in a collector. 

The air to water system is used for water production in water-scarce areas of the World. Around 1liter or more water can be prepared within 2 hours depending on the amount of moisture available for use. 

However, the major drawbacks of the systems are the "low rate of production","the manufacturing cost of the system", energy requirement, and installation complexities. That is why, both the duration required to produce water from the moisture and also the cost of production, deter customers from wide-scale utilization of the systems. 

So further research may be conducted in this aspect.

Five most innovative and sustainable water bottles

Cover Feature: Five most innovative water bottles selected by ODM V2 Five most innovative water bottles Water bottles are now becoming smart. Recently launched water bottles have the capability to track your hydration level and can remind you to drink water when the hydration level is below a predefined level. Some water bottles can either increase or decrease the temperature of the water in the container. Some alternatives come with blue tooth speaker/stirrer/fuser/wifi etc electronic devices. Some variation of smart water bottles has the ability to self-purify when needed. Here in this feature, we try to find the most innovative smart water bottles that are available on the eCommerce sites with the help of ODM. Now let us continue with the regular features : News about Sustainability Audi e-tron's used batteries in e-rickshaws by Nunam A new study finds inactive yeast could be effective as an inexpensive, abundant, and simple material for removing lead contamination from drinking

Five Most Popular English Movies (Fiction) on “Climate Change and its Impacts on Water Resources”

Students working in the field of climate change and water resource modeling often complain that they can’t see what they are predicting. They are confused about the reliability of their models and depend on some statistical indices to analyze the accuracy of their predictions. But if they want to have an idea about the reality of their predictions then they must watch the following five movies which simulate the future based on one or more climate change based impacts:.....

7 most recent application of GIS in the identification of suitable location for rain water harvesting

The water crisis has been rapidly increasing these days in many parts of the world which emphasize the importance of refinement in water management systems. Harvesting of rainwater(or rainwater harvesting(RWH)), which involves the collection and storage of rainwater for future use, is an area of increasing interest and one of the most suitable measures for ensuring water availability in the future days. The location of RWH is of utmost importance for the success of the water harvesting project. Locations for the construction of RWH structures like check dams, percolation tanks, bench terraces, contour ridges, and contour bunds can be determined by the application of Geographical Information System(GIS), Multi-Criteria Decision Making(MCDM), and different predictive models. Below are the seven recent case studies which demonstrate the procedure of location selection for RWH. 1) Case Study of Kiambu County-Kenya The ideal sites for five rainwater harvesting structures (bench terraces, ch
