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 augments it with heat from the system’s own mechanical equipment. The combined heat is used to: (1) evaporate water, (2) generate electricity with steam turbines, and (3) dry the brine byproduct.
Each Water Farm processes salt-water into distilled water at volumes 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 nearly 326,000 gallons per day. Because of their modular design, Water Farms can be built on an as-needed basis as a customer’s needs change over time. Construction, fit-out and delivery times are minimal as design and configuration are essentially the same for every unit.
Customers can achieve water independence and mitigate their exposure to volatility in water supply and costs. 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.
