When the battery discharges, the sodium and chloride ions are drawn to one chamber, leaving desalinated water in the other.
The plant uses reverse osmosis to produce about 10 percent of the area’s water supply.
The plant is capable of processing very harsh seawater (with salinity up to 52 g/l, temperature which may exceed 42 degrees Celsius and harmful algal blooms).
GE claims that if it proves successful, such a system could reduce the cost of water desalination by as much as 20 percent.
Demand for potable water in the GCC countries currently stands at about 3,300 MIGD, and is expected to rise to about 5,200 MIGD by 2020.
Topics include inland brackish and sweater desalination as well as oil and gas technologies.
The city’s new plant provided a solution to a shortage of evaporation ponds that collected the brine water effluent.
The GE expansion will increase the facility’s production capacity from 200,000 to 350,000 gallons of water per day.
