Decentralized or onsite wastewater treatment can facilitate alternative approaches to wastewater collection,**storage, treatment, and disposal in rural areas with low population densities and/or without access to**centralized sewer systems. The use of conventional onsite systems, such as septic tanks and leaching fields, at the present time are influenced by soil and site conditions. Advanced onsite wastewater technologies are**developed to overcome the site and soil limitations conventional treatments face. In addition to regulations**around treatment and effluent requirements vary depending on where a system's effluent discharge point is.**Onsite advanced wastewater treatment systems with integrated fixed film processes are a reliable solution in**these circumstances due to their ability to effectively and efficiently treat residential wastewater with variable flows and qualities. Submerged fixed film processes utilize naturally occurring bacteria to oxidize organic matter, remove nutrients and reduce solids, converting wastewater into a clear and odourless effluent. This research project will focus on the continued assessment and optimization of an innovative Waterloo Stack system for residential applications. The Waterloo Stack system will be refined and optimized for increased treatment performance under stress periods and increased flows. The results of this applied research will improve knowledge of the current system, enhance the product, and increase technical credibility.****

在人口密度低和/或无法使用集中下水道系统的农村地区，分散或现场污水处理可以促进废水收集、储存、处理和处置的替代方法。目前，化粪池和浸出场等传统现场系统的使用受到土壤和现场条件的影响。先进的现场污水处理技术**被开发出来，以克服传统处理所面临的场地和土壤限制。此外，有关处理和废水要求的法规**因系统污水排放点的位置而异。**现场先进的污水处理系统集成固定膜工艺是一个可靠的解决方案，在**这些情况下，由于他们能够有效和高效地处理不同流量和质量的生活污水。水下固定膜工艺利用天然存在的细菌氧化有机物，去除营养物质并减少固体，将废水转化为干净无味的废水。该研究项目将集中于持续评估和优化用于住宅应用的创新滑铁卢堆栈系统。Waterloo Stack系统将进行改进和优化，以提高在压力期和增加流量下的处理性能。这项应用研究的结果将提高对现有系统的认识，改进产品，并增加技术可信度。****
