This desalination process uses much less energy than RO

By Paul Grad |

An adsorption desalination and cooling (ADC) plant has been implemented at Solar Village near the Saudi Arabian capital of Riyadh, by King Abdulaziz City of Science and Technology (KACST; www.kacst.edu.sa). The project to build the plant resulted from a collaboration of King Abdullah University of Science and Technology (KAUST; Thuwal, Saudi Arabia; www.kaust.edu.sa), TAQNIA (Saudi Investment Co., Riyadh; www.taqnia.com) and Medad Technologies Pte. Ltd. at the National University of Singapore (www.medad-tech.com). General contractor Medad joined forces with KACST and Polish company NET to execute all engineering, manufacturing and installation works. The plant is said to be the world’s largest adsorption-chiller installation, with a cooling capacity of up to 1 MW and production of up to 100 m 3 /d of desalinated water. The plant’s electricity consumption is below 1.2 kWh/m 3 (about 75% lower than reverse osmosis). Power is required only for water pumps and valves. The plant’s operating costs are below $0.40/m 3 of water. The adsorption system consists of a pair of tube-fin heat exchangers, each packed with silica gel. The exchangers alternate between adsorption and desorption. In the adsorption mode, water vapor from the evaporator…
