Renewable Driven Desalination Systems
We turn seawater or brackish water into affordable fresh water 24 hours a day, without the use of expensive energy from the grid. Our efficient solution uses solar, wind or wave energy directly to fill up a water buffer installed at a hill with seawater. Through the force of gravity, the reverse osmosis process receives its required feed: pressurized seawater. We make sure the water buffer always contains water to enable constant water production, resulting in lowest cost.
How it Works
The waste energy of the reverse osmosis process is re-used to reduce the required elevation with 80% to 90 m or 290 ft for seawater. Take a look at the video & explore the working principle by clicking different components in the figure. We use the forces of nature at its best for an independent guilt-free water supply. By avoiding energy conversion losses, batteries & frequent maintenance, we offer savings up to 70%. The bigger, the better, as water cost come down with size of supply. Sizes start small and go up to millions of liters per day. Turn your water supply into an enriching experience for the people, planet and your profit.
Renewable Energy Source
Renewable sources as the sun, wind or waves are the only sources of energy used
Either PV panels or wind turbines or wave energy can be utilized, or a combination hereof, depending on the local situation. The footprint is determined by the source water salinity and the daily required fresh water production. The renewable energy sources will be placed at a suitable location of your preference. When renewable energy is available, the energy is directly converted into water displacement by the pump. There is no electricity source required, making the system suitable for off-grid applications.
Flat: Works Everywhere
Many properties are restricted in size and have limited access to elevation. To enjoy a reliable independent water supply, we have developed a solution that works everywhere. A combination of state-of-the-art solar energy and battery technology allows efficient reverse osmosis operation, while limiting the required battery size. All components can be integrated at preferred locations, to avoid impact on existing infrastructure and limit the required footprint. The high efficiency reverse osmosis is equiped with remote monitoring and designed for easy operation. All components are purpose built to survive corrosive environments and allow a long life-time. To realize lowest cost of water, the sizes of the solar energy, battery bank and reverse osmosis units are optimzed during the design phase. A grid-tied back-up can be included and the solution is offered from a few m³ up to millions of liters of potable water supply per day. Make sure to leave your contact details to enjoy affordable water from unlimited resources.
Already Green: Efficient Supply
We understand that water and energy are not always considered at the same time. If you already enjoy renewable energy or currently have an affordable energy solution in place, we can be your partner for the water supply. Especially for small-scale solutions, energy efficiency is usually lacking. We offer high-efficient reverse osmosis units that run below 3 kWh/m³ or 11 kWh/1,000 gallons energy consumption for seawater desalination, starting already at a few m³ or 1,000 gallons per day and going up to much bigger sizes! Just like all our solutions, water cost can be as low as 1.3 $/m³ or 5.0 $ per 1,000 gallons. Because of our experience in remote regions, we value the need for ease of operation & maintenance and can tailor the installation services to your needs. GSM based remote monitoring and control is included and all components are purpose built to survive corrosive environments. Join the resorts, private properties, communities & municipalities who have already made this step to independence. Why? Because we believe that a reliable access to safe and affordable water is of utmost importance.
Approach
- Are water kiosks or water shops for developing markets possible?

- What kind of guarantees can be given?
Where can the PV panels, wind turbine(s) or wave energy system be installed?
From an efficiency perspective it is preferred to locate the PV panels, wind turbine(s) or wave energy installation close to the source water intake pump. However it can be the case that it has the customer’s preference to place the PV panels for example on top or near of the elevated water buffer. There are no limitations to the possibilities. Roof mounted or ground fixtures solar panels can both be realized. Basically the options are endless as long as a power cable connection can be made between the renewable energy source and the intake pump.
