Nitrogen is one of the primary nutrients if in excessive amount pollute lakes, drinking water wells, streams, and wetlands. Most nutrients come from human activities and through municipal and home sewage systems. Wastewater treatment plants are required to remove nutrients such as nitrogen before their discharge to water bodies. This research investigates using BioCord biofilm technology to remove nitrogen from domestic wastewater. Currently, the BioCord technology has been successful in several municipal wastewater applications, including lagoons and wastewater stabilization ponds. Specifically, it has shown an ability to reduce levels of ammonia and biological oxygen demand at a lower cost from incoming waste streams and during cold weather conditions. Its semi-passive operation allows for high treatment efficiencies with minimal operator oversight, footprint, and operational/capital costs. However, as regulatory bodies continue to update effluent limit guidelines to keep up with growing environmental concerns, it is anticipated that reductions of total nitrogen, not just ammonia will become increasingly desirable. This research evaluates a new opportunity to manage nitrogen at a higher intensity and lower energy input. By understanding the mechanisms of total nitrogen removal within the BioCord Reactor and discerning the effect of oxygen delivery on total nitrogen reductions, Bishop Water Technologies has the potential to remain competitive in the wastewater treatment technology industry by providing a comprehensive solution with an ability to meet future targets for treatment.

氮是主要的营养物质之一，如果过量污染湖泊、饮用水井、溪流和湿地。大多数营养物质来自人类活动以及城市和家庭污水系统。污水处理厂被要求在排放到水体之前去除氮等营养物质。本研究采用BioCord生物膜技术去除生活污水中的氮。目前，BioCord技术已成功应用于多个城市污水处理，包括泻湖和废水稳定池。具体来说，它已经显示出在寒冷的天气条件下，以较低的成本从流入的废物流中降低氨和生物需氧量水平的能力。它的半被动作业可以在最小的操作人员监督、占地面积和运营/资本成本的情况下实现高处理效率。然而，随着监管机构不断更新污水限制准则，以跟上日益增长的环境问题，预计减少总氮，而不仅仅是氨，将变得越来越可取。本研究评估了在更高强度和更低能量投入下管理氮的新机会。通过了解BioCord反应器中总氮去除的机制，并识别氧气输送对总氮减少的影响，Bishop Water Technologies有潜力在废水处理技术行业保持竞争力，提供全面的解决方案，能够满足未来的处理目标。
