BQE Water Inc. is a specialized firm dedicated to providing comprehensive wastewater management and treatment services, primarily serving the mining and metallurgical industries globally. The company's operations extend across Canada, the United States, Latin America, China, and various other international regions, addressing diverse water quality challenges. They offer solutions for purifying a wide array of water streams, including mine drainage, surface run-off, seepage from waste rock, tailings water, groundwater, and both influent and effluent from lime plants. BQE Water effectively targets numerous contaminants such as metals, sulphate, selenium, nitrate, ammonia, and cyanide within mining contexts. For smelting and refining operations, their focus is on treating metals and sulphate, while their hydrometallurgical services tackle metals, cyanide, and acids. The company leverages several advanced proprietary technologies for contaminant removal and resource recovery. Their BioSulphide and ChemSulphide technologies, which utilize biological or chemical sulphide sources respectively, are employed for extracting dissolved metals from mining wastewater. The Met-IX system further contributes to general wastewater purification. To combat sulphate and hardness, BQE Water deploys Sulf-IX and Sulf-IXC technologies, complemented by onsite field testing. Selenium removal is achieved through their Selen-IX technology, with onsite demonstrations available for mine-impacted waters. Additionally, their SART technology for cyanide treatment is designed to eliminate metallurgical interference from cyanide-soluble metals and enable the recovery and recycling of cyanide in gold processing. Established in 1997, BQE Water Inc. is headquartered in Vancouver, Canada. The company operated under the name BioteQ Environmental Technologies Inc. until its rebranding in March 2017.
