大约有8亿人没有干净的饮用水。腹泻每年造成170万至200万人死亡（主要是儿童），这是饮用水质量和卫生条件差造成的。本研究的主要目的是展示使用离网饮用水生产系统从原水生产饮用水。在UWE布里斯托开发的离网饮用水生产系统（DWPS）将超滤（UF）系统与电化学活化溶液（ECAS）的原位生成相结合。ECAS在系统中有两个功能作用：管理UF系统中的生物膜和作为消毒剂。集成的原位探头（pH值、氧化还原电位、氯、电导率和溶解氧）与水质传感网络（pH值、水温、电导率和溶解氧）相结合，能够真实的实时监测DWPS的运行效率以及原水和生产饮用水的理化参数。原水和经处理的水的现场样品被送到一个经认可的实验室进行独立的化学和微生物分析，该实验室证明DWPS生产的饮用水符合饮用水检查局（DWI）的标准，具有生物安全性。来自原水源的样本被证明始终不适合人类消费，不符合DWI饮用水供应的几个标准，包括大肠菌群。这项研究表明，新型离网DWPS能够从严重生物污染的水源中生产DWI标准饮用水。
Approximately 800 million people live without clean drinking water. Diarrhoea is responsible for between 1.7 and 2 million deaths each year (primarily children) which are the result of poor drinking water quality and sanitation. The main aim of this study was to demonstrate the production of drinking water from a raw water source using an off-grid drinking water production system. The off-grid drinking water production system (DWPS) developed at UWE Bristol, combines an ultra-filtration (UF) system with in situ generation of electrochemically activated solutions (ECAS). ECAS has two functional roles within the system; to manage biofilms within the UF system and as a disinfectant. Integrated in-situ probes (pH, oxidation reduction potential, chlorine, conductivity and dissolved oxygen) coupled with a water quality sensing network (pH, water temperature, conductivity and dissolved oxygen) enabled real time monitoring of; the operational efficiency of the DWPS, and the physicochemical parameters of both the raw water source and the produced drinking water. Spot samples of both raw and treated water were sent for independent chemical and microbial analysis at an accredited laboratory which demonstrated that the DWPS produced biologically safe potable drinking water according to the Drinking Water Inspectorate (DWI) standards. Samples from the raw water source were shown to be consistently unsuitable for human consumption, failing several of the DWI standards for potable water supply, including coliform bacteria. This study demonstrated that the novel off-grid DWPS was capable of producing DWI standard drinking water from a heavily biologically contaminated water source.
