The facility has a seawater intake and pumping system which has a screening and filtration system. In order to ensure the seawater is of a suitably high quality for use in the RO Plant, the pre-treatment is composed of coagulation, dosing and flocculation, high-rate Dissolved Air Flotation (DAF) and Dual Media Filters (DMF).
The project is located on the northernmost extent of the Emirate of Umm Al Quwain in the United Arab Emirates. The specific plot of land was allocated by Etihad Water & Electricity and is immediately south of the Umm Al Quwain border with the Emirate of Ras Al Khaimah, approximately 20 km north of the city of Umm Al Quwain.
