Industry is essential to Canada's economic growth. These industries include: petroleum refineries; pulp and paper mills; pharmaceutical producers; cosmetic, dye and resin manufacturing plants, etc. These are all very important industries for Canada's economy. However, many produce liquid wastes that contain toxic contaminants that are also listed as priority pollutants. Many of these pollutants include: phenols, benzene, toluene, and other aromatic compounds. At high concentrations these chemicals can be harmful to various ecosystems, thus polluted waste water must be treated before discharging into the environment. Engineers have devised many techniques, such as: adsorption, chemical precipitation, biological treatment, etc. for removing such compounds, but most of these techniques have limited efficiency and/or are costly.

工业对于加拿大的经济增长至关重要。这些行业包括：石油炼油厂；纸浆和造纸厂；制药生产商；化妆品，染料和树脂制造厂等。这些都是加拿大经济的非常重要的行业。但是，许多产生含有有毒污染物的液体废物，这些废物也被列为优先污染物。这些污染物中的许多包括：苯酚，苯，甲苯和其他芳香族化合物。在高浓度下，这些化学物质可能对各种生态系统有害，因此必须在排放到环境之前对污染的废水进行处理。工程师已经设计了许多技术，例如：用于去除此类化合物的吸附，化学沉淀，生物处理等，但是这些技术中的大多数技术的效率有限，并且/或成本高昂。
