Five examples of Water Collected from Air

Video Link : https://youtu.be/AVQJCH-6psg

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.

How to calculate Water Quality Index considering the source type,intended use and climate ?

This WQI's primary innovation is that it calculates the WQI based on the type of source from which water is collected, the WQI's intended use, and the local climate at the time the samples were retrieved. The source or location from where the sample is collected has an impact on the quality of water which the index must incorporate at the time of calculation. The purpose for which the water quality index is calculated changes the weightage of the importance of the different quality parameters. For example, if WQI is calculated for knowing how drinkable the sample is then the weightage of coliform will increase compared to other parameters as the presence of coliform in the drinking water can not be permitted. The climate of the area from where the water is collected is another criterion to consider at the time of calculating the WQI. Based on the climate also the weightage of water quality parameters will vary. There will be a difference in the weight of importance if the sampl...

Five Most Extreme Hydrologic Events that changed the World

Typhoon Tip, Philipines(Collected from : CSMonitor ) Devastating storms, severe flood, acute famine conditions, etc. hydrological events of extreme nature has changed human history. Any event which is not normal is known as an abnormal event. In the case of hydrology, an event that has a return period of more than 100 years is considered Extreme. According to Herring(2020) of Climate.gov, "An extreme event is a time and place in which weather, climate, or environmental conditions—such as temperature, precipitation, drought, or flooding—rank above a threshold value near the upper or lower ends of the range of historical measurements." Though the threshold is not objective, few researchers have defined "extreme events as those that occur in the highest or lowest 5% or 10% of historical measurements". Some have described events by their deviation from the mean, or by their occurrence interval. Here the most severe five extreme hydrologic events were discussed which ...

Five open source free hydrologic models that you can use to model runoff of micro to macro watersheds

The principal objective of hydrologic models is to forecast the runoff of a surface water body, especially dendritic systems like rivers, streams, etc. The inputs to these models are generally Rainfall/Precipitation, Soil Characteristics, and other Climatic parameters like evapotranspiration, humidity, etc. LULC and geo-morphology are also used as the required input parameters of the hydrologic models. Both input and output of these models are temporally as well as spatially variable. Now the resolution varies with different models. Some models consider all the sub-basins to be a single watershed and determine the output based on the characteristics of this single watershed(lumped).In contrast, some other models will consider the {impact|effect} of each of the sub-basins on the central outflow of the watershed(distributed).In a few models, the entire watershed is divided into grids or units of uniform dimension. However, the accuracy is highest for the models, which considers the {impa...
