Reverse osmosis without the downsides

Already 4 billion people face water scarcity today. The key to moving from scarcity to abundance lies in the sea. Desalination uses a great deal of fossil energy and is a nightmare to maintain. Not anymore:  Elemental Water Makers provides efficient and easy reverse osmosis technology.

Powered by the sun, wind, waves or your own energy source.
You can get reliable access to clean water that’s affordable.

Elemental Water Makers received the 1st prize of the Mohammed bin Rashid Al Maktoum Global Water Award of the Deputy Ruler of Dubai. Out of 138 organisations active in desalination, they were chosen as the winner for their scalable and mature solutions.

Desalination without the huge energy bills

Reverse osmosis can be quite energy intensive, leading to high operational expenses. But it doesn’t have to be. Elemental Water Makers provide solutions with low energy consumption, even at small-scale.

Membrane fouling, rusty components, and an empty water storage in the morning are worries are of the past. Through constant operation and automated fresh flushes, the membrane lifetime is maximized. All components in contact with salt water have been carefully selected to resist corrosive environments and have a minimum of maintenance. Operation becomes stress-free through remote monitoring, control and automation.

Using elevation, powered by gravity

Gravity-assisted reverse osmosis Uses solar energy Off-grid using unlimited resources 24/7 water production Reduced brine impact

Turning seawater or brackish water into affordable fresh water, 24 hours a day, without the use of expensive energy. The off-grid solution directly uses solar, wind or wave energy to fill a buffer tank on a hill with seawater. Through the force of gravity, the reverse osmosis process receives its required feed: pressurized seawater. The system configuration makes sure the water buffer always contains water to enable constant water production, resulting in lowest cost of water. The waste energy of the reverse osmosis process is reused to reduce the required elevation with 80% to 90 m or 290 ft for seawater.

The buffer tank can be easily constructed using a corrugated, galvanized, coated steel tank with liner that is suitable for corrosive environments. A concrete cistern or basin are suitable alternatives. This uses the forces of nature at its best for an independent guilt-free water supply. By avoiding energy conversion losses, batteries & frequent maintenance, savings up to 70% can be realized. The bigger, the better, as water cost comes down with the size of production. Sizes start small and go up to millions of liters per day.

Footprint indication

The solutions can be designed for any requested water production. Provided as containerized units for plug and play installation, or integrate separate components to your preference into the (existing) infrastructure.

Example case: gravity

The problem

The resort receives its piped water from the island public utility company and faces a commercial rate of 5 $/m³. With a consumption of 50 m³/day, the water expenses weigh heavily on the resort’s operational expenses. Some days, there is no water available and some days, the quality doesn’t meet the high resort’s standards.

The solution

Enter Elemental Water Makers. Through investing in the Gravity-assisted solution, 70% savings on the water expenses will be enjoyed, resulting in over 1.100.000 $. The solution’s payback is within 4 years.

The benefits

Besides these financial savings, the resort has become independent on the availability and price of energy, provide high-quality water to their guest, save 100 ton CO2 per year, enjoys stress-free operation & remote monitoring and offer their clients a sustainable experience.

Assumptions: costs including installation and training | Yearly inflation of 2% | Local water price is 5 $/m³ | Water intake available | Financial lifetime 15 yrs | Technical lifetime >20 yrs | OpEx include consumables, spare parts and membrane replacement.

Water tariff in $/m3 Over $1,000,000 in total savings.
