Wastewater recycling has been and continues to be practiced all over the world for a variety of reasons including: increasing water availability, combating water shortages and drought, and supporting environmental and public health protection. Nowadays, one of the most interesting issues for wastewater recycling is the on-site treatment and reuse of grey water. During this study the efficiency of a compact Submerged Membrane Bioreactor (SMBR) system to treat real grey water in a single house in Crete, Greece, was examined. In the study, grey water was collected from a bathtub, shower and washing machine containing significant amounts of organic matter and pathogens. Chemical oxygen demand (COD) removal in the system was approximately 87%. Total suspended solids (TSS) were reduced from 95mgL(-1) in the influent to 8mgL(-1) in the effluent. The efficiency of the system to reduce anionic surfactants was about 80%. Fecal and total coliforms decreased significantly using the SMBR system due to rejection, by the membrane, used in the study. Overall, the SMBR treatment produces average effluent values that would satisfy international guidelines for indoor reuse applications such as toilet flushing.
污水再生利用在世界各地已经并将继续因其多种原因而得到实践，包括：增加水资源供应、应对水资源短缺和干旱问题，以及支持环境保护和公共卫生保护。如今，污水再生利用中最有趣的问题之一是现场处理和再利用灰水。在本研究中，考察了紧凑浸没式膜生物反应器（SMBR）系统在希腊克里特岛的一栋单户住宅中处理实际灰水的效率。在研究中，从浴缸、淋浴和洗衣机中收集含有大量有机物和病原体的灰水。该系统对化学需氧量（COD）的去除率约为 87%。总悬浮固体（TSS）从进水的 95mg/L 降低到出水的 8mg/L。该系统去除阴离子表面活性剂的效率约为 80%。由于研究中使用的膜的截留作用，粪大肠菌群和总大肠菌群显著减少。总的来说，SMBR 处理产生的平均出水值可满足厕所冲洗等室内再利用应用的国际指南要求。
