Global Water Farms presents the solar-powered Zero Liquid Discharge – Aided Evaporation Condensation (ZLD-AEC) “Water Farm” …
The Water Farm system is efficient, versatile and makes its own electricity. There are no membranes, no pressure-changes and no boiling of water. The technology mimics and enhances the Earth’s water cycle. It is one of the most cost-effective and environmentally sustainable desalination systems ever developed.
The ZLD-AEC system is based on a modular and scalable model. Water Farms are made up of individual, easily replicable units and each unit consists of four cells. Every unit captures solar thermal radiation and uses the heat to: (1) evaporate water, (2) generate electricity with steam turbines, and (3) dry the salt/mineral by-product.
Each Water Farm distills salt-water at volumes that can be scaled to meet the demands of utilities, water districts, agricultural or industrial operations, or entire geographic regions. A one unit Water Farm, our smallest configuration, will produce 1 acre foot of distilled water per day (af/d) or more than 325,000 gallons per day. Because of their modular design, Water Farms can be built on an as-needed basis as demand changes over time. Construction, fit-out and delivery times are minimal as their configuration is essentially the same for every unit.
With Water Farms, clients can vertically integrate their water supply and water treatment needs to achieve water independence. Clients will mitigate their exposure to stricter regulations for discharging water and to long-term cost volatility in accessing clean/fresh water. Financial analysis and projections show GWF will be extremely competitive when compared to current deployed technologies.
The company’s first patent, covering its novel method for producing distilled water from salt-water or other degraded water sources was issued on December 4, 2018. A second patent was issued on September 17, 2019. Other continuation patent applications are in process. Global Water Farms has a fully operational trailer-sized mobile prototype which demonstrates the efficacy of the technology. The company is currently constructing its first full-scale system in the desert in Southern California.
