Produced Water from Gas Fields as a Non-Conventional Water Resource
Produced water (PW) is the highest volume wastewater related to oil and gas production. PW from gas fields in Qatar is usually injected into onshore deep wells for disposal after acidification, and oil and H2S removal. Qatar National Vision 2030 mandates the increased usage of highly treated wastewaters to enhance the sustainability of water sources in the country both for agricultural and landscaping irrigation practices. Use of PW could be an appealing alternative for diversification of water resources in Qatar as well as addressing the environmental and economic constraints of traditional PW disposal practices. As the demand and production of oil and gas is continuing to increase globally, the environmental footprints associated with this production and more specifically with generation of produced water (PW) are increasing. Furthermore, as the scarcity of freshwater supply is increasing, PW can be a crucial source of water after suitable treatment. Since PW is a very challenging mix of different contaminants with varying concentrations, in this study we tested the efficiency of different water treatment processes such as wetland treatment, adsorption with AC, coagulation-flocculation, and RO/NF for PW treatment to meet irrigation and landscaping quality standards. The comprehensive physicochemical analysis of PW samples before and after treatment has been performed.
