Case of the Week: Week 35 - Desalination Plants
Are you an interested in water supply and desalination? Are you an investor or an entrepreneur working with utility scale water supply or purification? The case of the week at SaltX Labs this time is focused on SaltX Future Energy Hack solutions for islands and landlocked countries. Using solar energy for water desalination is a very effective way to produce clean water. Join SaltX Future Energy Hack and make this case a reality - www.saltxlabs.com/hack
Methods of solar distillation have been employed by humankind for thousands of years. The first solar distillation patent was granted in 1870 in the USA. Charles Wilson, a Swedish engineer, began building a direct method solar powered distillation plant to supply freshwater to workers at a salt and silver mine in Las Salinas, Chile. Of the estimated 22 million m3 of freshwater being produced a day through desalination processes worldwide, less than 1% is made using solar energy. Other methods that heavily rely on fossil fuels have been widely used and were cheaper to maintain in the past. It is estimated that desalination plants powered by conventional fuels consume the equivalent of 203 million tons of fuel a year.
With the advancements in the solar energy harvesting and a radical decrease in the cost of the solar collectors, new technologies challenge the fossil fuel based desalination methods. SaltX is one of them. Using SunCool technology, harvesting solar heat can be done about 4 times more efficiently (comparing heat capacity of water vs. salt). SaltX technology provides both - heat and cooling which are required to evaporate water and chill down the pure water vapour. Due to a different absorption spectrum SunCool technology is about twice as efficient as a photovoltaic panel and requires less maintenance. Lastly, the angle that SunCool is facing the sun is less important compared to the photovoltaic panels. SaltX Technology and SunCool are ideal for desalination process.

SaltX LABS brings you a new challenge every week. We encourage you to collaborate with others who are interested in the SaltX Technology and come up with solutions to world’s challenges. If you have an idea - we will support you from ideation to building a successful company!
The Water Abundance XPRIZE challenges teams from around the world to revolutionize access to fresh water by creating a device that extracts a minimum of 2,000 liters of water per day from the atmosphere using 100% renewable energy, at a cost of no more than 2 cents per liter.
The Water Abundance XPRIZE will create decentralized access to water, giving people the power to access fresh water, whenever and wherever they need it.
Thanks a lot for sharing @midnightmastermind and welcome to the SaltX Labs community! Do you have any contacts to the finalist teams for this challenge? We'd love to find ways to further optimize these solutions with our knowledge and technology!
We have new US patented and patent-pending technology for water distillation or desalination and extraction processes.
Our technology uses unique evaporative cooling, humidification and condensing processes for producing distilled water, cold, power and air conditioning systems. The technology produces affordable clean water from any water source and are powered by low temperature heat. This technology is the new but proven thermodynamic conception through capture energy from air and it make water through natural renewable energy.
I would be happy to share with saltxlabs.com readers detailed information about our technologies to look for synergy in Air 2 Water and Water 2 Water applications.
You can see in attachment 1 a data from Gas Technology Institute, USA (GTI) report confirming the M-Cycle for Distillation technologies reduces consumption of energy about 10 times. More detail information is disclosed in GTI report Integrated Industrial Wastewater Reuse Via The Maisotsenko Cycle Heat Recovery Process.
The attachment 2 is M-Cycle illustration expressed on the Psychrometric Chart. It is a comparison of the distillation processes with the M-Cycle and the best existing “dewvaporation” distillation method. Red color is the M-Cycle; blue color is the best existing process. You can see from a chart how much water is evaporated (and it can be condensed as a distillate) through the M-Cycle and through the best existing process. There is difference more than 5 times, when temperature is 160 F (70 C) and more than 12 times at temperature 500 F (260 C).
The second M-Cycle breakthrough next to unique evaporative cooling, humidification and condensing thermodynamic processes is innovative evaporative material for plates in Heat and Mass Exchange apparatus, HMX.
Water Abundance Prize is a great event sponsored by Tata and Australian Aid. However, they are looking for Water from Air extraction technology breakthrough. The topic above is about Water from Water technology, or desalination of sea water or treatment of waste water. Air2Water is based on adsorption, evaporation and condensation. Water2Water mostly use membrane or distillation technology (water evaporation and distillation). There is Maisotsenko Cycle regenerative water evaporative and condensing technology with unique advantages in both types of A2W and W2W technologies.
Hi @mcycle! Thank you very much for sharing this promising technology! We are reviewing it with the technical team! We would like to investigate more how heat storage can help in this process of Maisotsenko Cycle distillation.
Another idea and patented conceptual technology is using of M-Cycle water cooling, treatment and desalination in water towers in the night time instead of building thermsl storage with huge (30% of total) CapEx. There is a bunch of patent pending technologies which our R&D team can introduce to SaltX or industry partner. We have developed such water cooling and water tower innovations as usage of desiccant in case of total absence of water or distillated water generations; reuse of water (including sea- or salt water); formation of counterflows; optimal day and night performance (without energy- and thermal storage at night); evaporative condenser realization; creating of fluidized bed instead of evaporative plates; brand new thermal resistant evaporative material.
Probably, all technology and innovation experts might know about M-Cycle is publicly available information from scientific research papers dated a few years ago. Some our ideas seem unrealistic before the entire understanding of water cooling thermodynamic concept is changed. One thing is evaluating breakthrough technology measuring with ruler, another thing is evaluation with laser rangefinder. Interested party and our R&D team can create new unique industrial product with unbeatable competitive advantages. The second feature we offer additionally to new thermodynamic concept is composite material with enormous evaporative ability and heat-resistant at the same time.
@mcycle I'm not that skilled in the technicalities of Maisotsenko cycle. Can you explain in simple terms how it works and how we can generate energy or energy storage and how can we use SaltX energy storage for it?
