waterfx sees solar desalination as one way to address the world's water problem - heat transfer film
WaterFX's founder and chairman, Aaron Mandell, looks at California's water issues like a classic entrepreneur.
Where others see problems, he sees opportunities for improvement and profitability.
This opportunity is huge.
It is well known that access to clean water is an increasingly serious problem worldwide.
However, few places have complex and challenging water problems like California, which has been dealing with water problems for generations (
Some may remember 1974 Jack Nicholson, Feyer dunneville movie Chinatown, which focuses on the California water war in early 1900).
In the country, the issue is very complex, layered in the realities of complex rights histories, claimants, and excessive demand for limited supply.
Water issues are also inextricably linked to energy issues: pumping, processing and moving water requires a lot of energy.
Therefore, the problem of water is not only limited to H2O, it is also an expensive energy problem.
Mandel wants to change this reality.
He has a vision of how this can be achieved, starting with clean Modular Technologies and open source approaches, and he hopes that this will spur the growing community of solution providers.
His company, WaterFX, created a solar energy-
The power seawater desalination system is not only benign from the perspective of energy, but also makes the agricultural environment better.
Over the past six months, WaterFX has successfully tried out a 6,500-square-foot system with Panoche Water District, California, producing nearly 500 gallons of clean Water per hour
Panoche, a water district in California, plays a leading role in resolving the state's water crisis.
Following the success of the pilot, the water district has now agreed to work with Mandel to expand the system to 2,200 acresfeet per year.
The following is how the system works: it replaces the traditional seawater desalination method commonly used to treat seawater, which uses high
The pressure reverse osmosis system forces salt and other solids through the membrane, and WaterFX cleans the water by using a concentrated solar stationary.
Using existing technology, it uses a 400 KW parabolic solar cell originally designed for power generation.
The solar cell concentrates the energy of the sun and heats the pipeline containing a heat transfer fluid that transmits heat to the heat pump to further improve efficiency.
Then, use this heat in the distillation process to vaporize the clear water from the source water (
In this case, agricultural drainage containing salt, fertilizer and other impurities).
The condensate is then recycled as pure H2O.
Since the sun does not always shine, the energy storage system is used to keep excess heat so that the process can run around the clock.
Mandell-studied groundwater engineering at school and participated in previous waterrelated start-ups -
In recent years, people have begun to shift to energy work and are convinced that energy-
Water relations are an area of concern.
The experience of the pilot has led to the belief that scaling up is feasible.
Mandel also recognized that his technology must be superior to other methods in order to succeed.
He pointed out that in the traditional reverse osmosis method, fuel represents 60-
70% of the total cost.
Mandel believes his technology can be at least 20-
The price is 30% cheaper and the function is stronger, especially considering the overall operating cost.
The total operating cost of WaterFX is approximately $450
He expects these to decline as the scale expands and start to decline from there.
He commented that his cost was not only lower, but the overall approach was also better.
He thinks these recycled elements are also valuable.
"We haven't reached the point where we sell by-products, but this is probably the most profitable source of income for us because there is a lot of value in dissolving salt and metals.
In order to expand the scale, people will think that the beginning-
Up requires venture capital.
That's not the case, Mandel said.
Financial instruments supporting new projects come from monetization of the water contract itself.
Mandel pointed out that there is another reason why he avoided venture capital, and he pointed out that this may be very helpful in the right case.
The risk community may not be able to find the open source approach they like.
While Mandel naturally wants to make a profit from this adventure, he also has a broader mission that will change the way people think about water issues, and use the knowledge he has learned to serve the greater social interests.
Mandel's dream is to have an impact on a global scale.
He also pointed out that it is possible to improve the agricultural environment.
The problem related to the accumulation of salt in the irrigation soil is not a new problem.
In fact, due to the accumulation of salt in the irrigation soil, the agricultural output of meisondamia was greatly weakened, which eventually led to its decline.
Mandel saw the great potential of soil restoration through this technology.
Finally, Mandel believes there is a cost to WaterFX-
This is effective, environment-friendly and relatively easy to adopt for the open source community.
He hopes his technology will spur a new approach.
