Optimization of BioCord technology as wastewater nitrification upgrade unit

首个联邦废水系统排放法规（WSER）要求至少进行二级废水处理或同等处理，并规定了未电离氨（NH3）的排放浓度限值（Canada Gazette，2012年）。全国800个治疗设施已被确定为可能需要升级，以完全符合新的联邦法规。Bishop Water Technologies BioCord环状聚氯乙烯技术为全国各地的各种处理设施提供了有效、紧凑和低成本的升级解决方案。然而，目前的文献表明，附着生长技术，如BioCord系统，显示出有效处理工艺和去除氨的前景，但目前缺乏公开的信息，并且尚未在该领域中充分探索以使其进入市场（Verma等人，2006年）。

The first federal wastewater systems effluent regulations (WSER) require a minimum of secondary level wastewater treatment or equivalent and specifies an effluent concentration limit for unionized ammonia (NH3) (Canada Gazette, 2012). 800 treatment facilities across the country have been identified as potentially requiring upgrades to fully meet the new federal regulations. The Bishop Water Technologies BioCord looped polyvinyl chloride technology offers the potential of an effective, compact, and low-cost upgrade solution to various treatment facilities across the country. However, current literature demonstrates that attached growth technologies, such as the BioCord system, show a promise for efficient treatment processes and the removal of ammonia but currently lack publicized information and have not been adequately explored in the field to enable their entrance into the market (Verma et al., 2006).
