Desalitech is reducing the cost, energy and waste of desalination, while increasing the speed and revenue of the process
Desalitech, an Israeli startup and developer of technology for water desalination, has completed a third round of funding worth $5M. The current funding round was led by Liberation Capital, the VC firm founded by former executives of General Electric, and the same firm behind the company’s second round of funding, which afforded the company $6.25M.
Safe drinking water
Desalitech Israel are the creators of a closed circuit desalination system, which turns seawater into drinking water. The company boasts the ability to reduce desalination costs by 20 to 60 percent through their unique water filtration system, and can reduce energy consumption by up to 30%, and waste generation by 70%.
In practice, the company uses reverse osmosis technology, which requires two cells. The A cell fills with water containing a high concentration of salts, the B cell is filled with water with a zero salt concentration. Between the two cells is a permeable membrane through which only water can pass. High pressure is exerted on the water in cell A, and forces it to pass into cell B.
Desalitech’s product utilizes membranes that allow for a fewer number of molecules or ions to pass through them, and required a lower water pressure than most desalination systems on the market today. In addition, the company’s desalination process operates at a faster rate, processing water at speeds of 2 to 3 miles per hour, compared to a speed of 1.5 miles per hour in existing desalination systems.
So, along with cost and energy savings, the company allows for a significant reduction in concentrated salts secreted during desalination, in effect, reducing the amount of wasted water, and the overall environmental pollution generated from the process.
Desalitech was founded by Professor Avi Efrati under the name Advanced Desalination Technologies, as a platform for the development and commercialization of closed circuit desalination systems. While Avi Efrati is behind the company’s technology development, the management is entrusted to his son, Nadav Efrati. Currently, the company employs approx. 10 people at its two offices, one in Tel Aviv, Israel, the other in Newton, Massachusetts, USA. Strategically, the company is looking to foster partnerships with other entities, creating and managing large desalination projects around the world, using their technology.
