"AQR has identified a clear market opportunity for a viable, sustainable and reliable drinking water treatment process at small community and single household scale. Currently, the UK water industry heavily subsidises treatment in rural, smaller communities since the cost of providing effective treatment makes it unaffordable for these customers.The AQR Safe Water(r) process provides effective disinfection in raw surface waters that can be particularly challenging due to a high organic, coloured content. Additional pre-treatment is necessary for current disinfection processes to operate effectively. UV disinfection can only operate in clear water, has significant power requirements and requires regular replacement of bulbs. Chlorine disinfection has been trialled at small-scale but failed due to the dosage requirements causing ineffective disinfection by over- or under-dosing.This project is concerned with understanding the interaction between the AQR Safe Water(r) disinfection process and organic content in raw surface water, to confirm the treated water is safe for human consumption. Current regulation is based on UV and chlorine disinfection that requires UV Transmittance (UVT) to reach 100 % and organic content to be reduced to zero, so that UV disinfection can operate effectively and chlorine does not produce potentially carcinogenic byproducts. However, water is visibly clear above 60 % UVT and if not using chlorine, there is no risk of producing harmful byproducts. The outputs from this project will help inform regulation and expedite AQR's market entry and retain AQR's significant competitive advantage.Supply of safe drinking water is taken for granted by developed nations, but is becoming under threat from ageing infrastructure, an increasing global population and climate change. Water security is a global challenge, alongside strict global sustainability and resource-efficiency targets to be achieved by 2030 \[source: UN Sustainable Development Goal 6\]. Globally, 8 out of 10 people in rural areas still have no access to safe drinking water \[source: UN Millennium Development Goal 7\]. The demand for water is rising, set to exceed supply in the UK as early as 2025 in highly populated areas \[source: BBC\], while the rising cost of water creates incentives for water companies to explore water conservation and re-use. The AQR Safe Water(r) system is a low-power process that uses no added chemicals and has a flexible, modular unit assembly. It can be easily operated using mains, solar or wind power and is ideal for single households and small communities, i.e. in rural and dispersed environments, globally."

“AQR 已经确定了在小社区和单一家庭范围内采用可行、可持续和可靠的饮用水处理工艺的明确市场机会。目前，英国水务行业对农村、较小社区的处理提供大量补贴，因为提供有效处理的成本使这些客户无法承受。AQR Safe Water(r) 工艺可对原地表水进行有效消毒，由于有机、有色含量高，这尤其具有挑战性。额外的预处理是必要的 当前的消毒流程有效运行。紫外线消毒只能在清水中进行，对电力的要求很高，并且需要定期更换灯泡。氯消毒已进行小规模试验，但由于剂量要求导致剂量过多或剂量不足而导致消毒效果不佳而失败。该项目旨在了解 AQR Safe Water(r) 消毒过程与原始表面有机物含量之间的相互作用 水，以确认处理后的水可供人类安全饮用。目前的规定是基于紫外线和氯消毒，要求紫外线透过率（UVT）达到100%，有机物含量降至零，这样紫外线消毒才能有效运行，并且氯不会产生潜在的致癌副产物。然而，水在 UVT 超过 60% 时明显清澈，如果不使用氯，则不会产生任何影响。 产生有害副产品的风险。该项目的成果将有助于为监管提供信息，加快 AQR 的市场进入，并保持 AQR 的显着竞争优势。 发达国家认为安全饮用水的供应是理所当然的，但正面临基础设施老化、全球人口增长和气候变化的威胁。水安全是一项全球性挑战，同时还要到 2030 年实现严格的全球可持续发展和资源效率目标\[来源： 联合国可持续发展目标 6\]。在全球范围内，农村地区十分之八的人仍然无法获得安全饮用水[来源：联合国千年发展目标7]。英国人口稠密地区的水需求不断上升，最早将于 2025 年超过供应[来源：BBC]，而水成本的上涨则激励自来水公司探索水资源节约和再利用。 AQR 保险箱 Water(r) 系统是一种低功耗工艺，不使用任何添加的化学品，并具有灵活的模块化单元组件。它可以使用主电源、太阳能或风能轻松操作，非常适合单个家庭和小型社区，即全球农村和分散的环境。”
