Reed-Bed Technology for Treating Oil-Production Water in the Sultanate of Oman

Safe and environmentally benign disposal of produced water is a major concern in the Sultanate of Oman. Petroleum Development Oman (PDO) produces 600 000 m3/d of water, which is contaminated with petroleum hydrocarbons (10 to 800 mg/L), traces of phenols, emulsifiers, and a wide range of metals at varying concentrations. It also shows a relatively high electrical conductivity. The current methods of disposal into shallow and deep aquifers are no longer meeting environmental regulations. The use of reed-bed technology for the treatment of produced water significantly reduced organic- and inorganic-contaminant concentration in the effluents.
