Qatar has been experiencing rapid infrastructure development and population growth, which led to the exponential growth in water demand and desalinated water production. Although major desalination processes in Qatar are based on thermal technology, now the trend is shifting to the membrane based reverse osmosis (RO) processes due to environmental factors and energy efficiency. Two major RO desalination projects are underway in Qatar. The Ras Abu Fontas project built at a cost of QR1.75 billion will have a capacity to provide 36 MIGD (164,000 m3/day) of desalinated water daily to meet the needs of about 1 million people in the country. Umm Al Houl will produce 284,000 m3/day per and will reach 614,000 m3/day after the start-up of the new facility. This is the first time that reverse osmosis technology has been used on a large-scale production plant in Qatar. Previous implementation of RO in Qatar has been limited and on small scale, such as the trial in Dukhan, where 750 m3/day of high salinity water was treated for boiler feedwater. The highlights of the RO desalination plants in Qatar are coagulation, dissolve air floatation, sedimentation, UF, granular media filtration, multi-stage RO units (pass, trains etc.) and high pressure multistage centrifugal pumps with energy recovery device (ERD). Qatari waters are very complex with highest salinity in the Gulf Cooperation Council (GCC) region and high level of colloids and organic matter. A systematic interpretation of critical combinations of feed water, pretreatment and membranes and adequate conclusions can avoid setbacks of reverse osmosis processes. This presentation focusses on the RO challenges in Qatar such as turbidity issues, membrane fouling and pretreatment and can be resolved through proper operation and maintenance of the RO plants.
