Enhanced nutrient uptake in wastewater systems using an integrated attached growth membrane-bioreactor system

废水在加拿大的每个社区都是不可避免的；然而，废水的处理和处理在每个社区并不一定是一致的。废水中的有机物质和营养物质，如氮和磷，可能对接收水体产生重大不利影响，并可能影响鱼类种群，增加藻类生长，并导致富营养化。为了促进水生生态系统的改善，联邦政府最近制定了废水系统废水管理条例(WSER)，要求对废水进行最低二级废水处理，并使用非离子化氨(NH3)。氨是水生生态系统中已知的有害物质，会导致急性和慢性毒性问题，包括鱼类死亡。然而，低温会阻碍性能。Bishop Water Technologies Inc.拥有一个附属的生长系统BioCordTM，该系统有可能有效地处理脱氨工艺，但调查较低温度影响的研究有限。此外，膜生物反应器和附着生长系统有可能在不同的气候条件下提供有效的二级废水处理和氮磷营养去除。

Wastewater is inevitable in every community in Canada; however, disposal and treatment of wastewater is not necessarily consistent in every community. Organic material and nutrients, in wastewater, such as nitrogen and phosphorus have potentially significant adverse impacts on receiving water bodies, and can affect fish populations, increase algae growth, and cause eutrophication. In order to facilitate improvements in aquatic ecosystems the federal government recently produced the wastewater systems effluent regulations (WSER) which mandate a minimum secondary level wastewater treatment of effluent unionized ammonia (NH3). Ammonia is a known deleterious substance in aquatic ecosystems which results in both acute and chronic toxicity issues, including fish death. However, low temperatures impede performance. Bishop Water Technologies Inc has an attached growth system, BioCordTM that has the potential to efficiently treat processes for ammonia removal however research investigating the impact of lower temperatures is limited. Furthermore, membrane bioreactors and attached growth systems have the potential to provide efficient treatment of secondary wastewater and nutrient removal of nitrogen and phosphorus under varying climate conditions.
