Al Ghubrah Desalination Plant in Oman passed the COD.
18 May 2016, News release from Cadagua
Al Ghubrah SWRO desalination plant achieved last February commercial operation after successful completion of the 30 day period acceptance tests in the first trial.
The plant has proved to deliver the nominal capacity of 191.000 m3/d meeting challenging technical and operation requirements. Since the start-up in last June, the plant delivered more than 20 million m3 of water to the Public Authority for Electricity & Water. The plant has a capacity to supply water to 700,000 population in the Muscat metropolitan area. With this new infrastructure the Oman Power and Water Co. will shut down old and less energy efficient desalination facilities.
The JV led by Cadagua has designed, built and commissioned the plant in a record period not ever seen in the country for such a complex infrastructure project. The facilities had to be designed to fit into a narrow footprint of 5.6 ha. During construction, peaks of more than 2,000 workers had to perform at site, which made it really challenging in terms of scheduling and ensuring H&S at site. A total 9.5 mn man-hours were spent in construction with a record of two 3.5 mm-h periods with cero LTI (loss time due to Injury), which proves the JV commitment with the H&S. Moreover the JV successfully met the Omani work-force requirements and more than 30% of the subcontracting was allotted to local companies.
Al Ghubrah plant is based on the RO process, with a pre-treatment incorporating DAF units, to be operated in case of high algae/solids (red tide) is observed in the seawater, for a high availability and non-interrupted water production. Also the design incorporates the provision to produce drinking and irrigation water with Boron <0.5mg/l, with a full RO second pass. The Plant produces water at a record low energy consumption at 3 kWh/m3 (for current drinking water standards).
