Siemens has received a follow-up order from the A3C consortium (Rawafid Industrial, Advanced Water Technology, SETE and Al Fatah) to equip eight seawater desalination plants in Saudi Arabia with electrical equipment. The new seawater reverse osmosis plants are spread along the west coast of Saudi Arabia. The total capacity of the plants will be 240,000 m3/day, with a power consumption of just 3 kW/m3 of produced water, which is below the usual value and will provide significant energy savings. The scope of supply from Siemens includes hardware and software engineering, power distribution, PCS7 automation, medium and low voltage converters, Industrial Ethernet communication technology and process instrumentation for eight reverse osmosis plants, plus plant commissioning. The project will follow a tight schedule, with commissioning planned from autumn 2019.
Almost 95 percent of water on earth is saline and cannot be used as drinking water or for irrigation purposes. Seawater desalination provides an opportunity to obtain additional drinking water or process water for people, industry and agriculture. In 2017, Siemens was commissioned by Rawafid Industrial and Advanced Water Technology (AWT) to set up a drinking water production plant on the coast of the Persian Gulf.
Rawafid Industrial relied on solutions from Siemens for the electrical equipment, automation with integrated drive technology, communication and instrumentation. Through the efficient use of solar power, the plant reduces carbon dioxide emissions significantly compared with plants supplied with energy from non-renewable sources.
