Organizing the Waterloo Biofilter biological process for treating wastewater concentrated by extreme water conservation plumbing

滑铁卢生物滤池系统公司是一家加拿大拥有和运营的公司，开发、设计、制造和维护先进的现场废水处理系统。滑铁卢生物滤池技术为住宅(个人住宅和集群式或公共系统)、商业(高尔夫球场、餐厅、度假村等)、轻工业和小型市政应用提供各种创新的分散式污水处理解决方案。所有滑铁卢生物滤池处理单元都使用获得专利的高效过滤介质来支持和维持降解废水中污染物的生物种群。能源与环境设计领导者(LEED)绿色建筑评级体系是第三方认证计划，是国家认可的高性能设计、施工和运营基准 绿色建筑。LEED项目通过在人类和环境健康的五个关键领域设定建筑性能标准，鼓励和加速全球采用可持续的绿色建筑和发展实践：可持续场地开发、节水、能源效率、材料选择和室内环境质量。滑铁卢生物滤池的紧凑性和高处理水平提供了可用的最小系统和处理场足迹之一，有助于减少开发项目的总占地面积，并最大限度地扩大植被覆盖的空地。然而，LEED绿色建筑废水具有固形物含量低、氨氮浓度高等特点，与常规废水相比处理难度较大。因此，在生物滤池之前评估氮碳比(N/C)和在化粪池和泵送池中固体停留时间的影响对于优化生物滤池是至关重要的。 滑铁卢生物滤池处理LEED绿色建筑废水并确定最佳设计标准。

Waterloo Biofilter Systems Inc. is a Canadian-owned and operated company that develops, designs, manufactures and maintains advanced onsite wastewater treatment systems. Waterloo Biofilter technology provides a variety of innovative decentralized sewage treatment solutions for residential (individual homes & clustered or communal systems), commercial (golf course, restaurant, resort, etc.), light industrial and small municipal applications. All Waterloo Biofilter treatment units utilize a patented high-efficiency filter medium to support and sustain biological populations that degrade contaminants found in wastewater. The Leadership in Energy and Environmental Design (LEED) Green Building Rating System is a third-party certification program and the nationally accepted benchmark for the design, construction and operation of high performance green buildings. The LEED program encourages and accelerates the global adoption of sustainable green building and development practices by setting out building performance standards in five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality. Waterloo Biofilter's compact nature and high treatment levels provide for one of the smallest system and disposal field footprints available, helping to reduce the development's total footprint and maximize vegetated open spaces. However, LEED Green Building wastewaters have unique characteristics i.e. low solids content with high-ammonia concentration and thus its treatment is challenging compared to the conventional wastewater. Therefore, evaluating the effect of nitrogen to carbon (N/C) ratio and the solid retention time in the septic and pumping tanks prior to the biofilter is essential to optimize the Waterloo Biofilter treating LEED Green Building wastewaters and identify the optimum design criteria.
