The oil sands in Northern Alberta are one of the largest unconventional oil deposits in the world. Bitumen is extracted from oil sands using water from the Athabasca River. The bitumen extraction process produces large volumes of oil sands process-affected water (OSPW), a complex, alkaline mixture of toxic organic and inorganic compounds. Oil sands companies are required to store all fluid wastes generated from bitumen extraction in tailings ponds around the mining sites. Appropriate treatment technologies are urgently needed to increase reuse and recycling of OSPW, and to improve the quality of OSPW so it can be safely discharged in the natural environment.

北方阿尔伯塔的油砂是世界上最大的非常规石油矿床之一。沥青是用阿萨巴斯卡河的水从油砂中提取的。沥青提取过程会产生大量的油砂工艺影响水（OSPW），这是一种有毒有机和无机化合物的复杂碱性混合物。油砂公司必须将沥青提取产生的所有液体废物储存在采矿场周围的尾矿池中。迫切需要适当的处理技术来增加OSPW的再利用和回收，并提高OSPW的质量，使其能够安全地排放到自然环境中。
