Al-Khalaf and Abdul Aziz Al-Anzi | | Abstract : Al Qurayyat City, Al Jouf Region, KSA relies merely on groundwater wells (TDS
= 1157–1680 ppm) in Ain Al Bayada, Tabarjal and Busaita, 40, 140 and 180 km southern Al Qurayyat, respectively. Al Qurayyat has only one desalination plant that was constructed in 1985. The productivity of the plant is 150,000 3 m /month; depending on the number of work hours. The high quality water is free of bacteria.
