Abstract
The main two supply of potable water to Amman city are Zai water treatment plant (represent 60%) and Wadi Ma’in, Zara, and Mujib (WMZM) water treatment plant (represent 30%). WMZM receives raw water from three main sources originally flowing to the Dead Sea, now collected and conveyed to a raw water reservoir at the treatment plant to produce about 110,000 m3/day. WMZM was commissioned in 2006 and still operating at the original design capacity. WMZM water treatment plant and its conveyance system are presently operated by Jordan Water Company—Miyahuna. This paper covers the plant description, original design parameters, and RO membrane performance after more than five years of operation.
