Securing access to clean water is a major global challenge with water demand set to increaseby 50% over the next 50 yrs. Desalination technologies plays a vital role in the production ofclean water providing an unlimited & constant supply of high quality water for humanconsumption, industrial & agricultural application.With lower capital costs & energy requirements, Reverse Osmosis (RO) is the dominantmethod for desalination, with over 20,000 operational RO plants globally representing 70% oftotal world desalinated water production capacity. Despite RO’s widespread application, allRO Membrane (ROM) elements are subject to fouling by dissolved & suspended materialspresent in the feedwater which significantly impact operational efficiency leading to systemdamage. Typically membranes require cleaning every 3 – 12 months and replacing every 2-3yrs due to fouling .Genesys Manufacturing Limited, a leading developer of antiscalants, cleaners & biocides forthe ROM mkt, aim to address the mkt need for improved membrane cleaning through thedevelopment of a novel air assisted chemical cleaning process known as “Genairclean”. Thisis based on the use of the “Genairator” a proprietary venturi based dynamic air injector tocreate microbubbles for physical agitation, combined with the development of effervescentcleaning reagents. Basic proof of concept studies have indicated that Genairclean coulddeliver an increase in cleaning efficiency by up to 40% at no additional cost, resulting in asignificant improvement in plant efficiency. A reduction in electricity pumping costs &extended membrane life by 1-2 yrs is also foreseen.The technology will be applied across RO & Nanofiltration (NF) membranes used in thedesalination process including the industrial, commercial, municipal, healthcare,governmental & non-profit sectors worldwide. The approach offers the potential torevolutionise the membrane chemical cleaning mkt worth $625M resulting in savingsc.$52m/yr

确保获得清洁水是一项重大的全球性挑战，未来50年的水需求量将增加50%。海水淡化技术在生产清洁水方面发挥着至关重要的作用，为人类消费、工业和农业应用提供无限量和持续的高质量水供应。由于资本成本和能源需求较低，反渗透（RO）是海水淡化的主要方法，全球有超过20，000个运行中的反渗透装置，占全球淡化水总产能的70%。尽管反渗透应用广泛，但所有反渗透膜（ROM）元件都会受到给水中存在的溶解和悬浮物质的污染，这会显著影响运行效率，导致系统损坏。通常情况下，由于污染，膜需要每3 - 12个月清洗一次，每2- 3年更换一次。Genesys Manufacturing Limited是ROM市场的阻垢剂、清洁剂和杀菌剂的领先开发商，旨在通过开发一种称为“Genairclean”的新型空气辅助化学清洁工艺来满足市场对改进膜清洁的需求。这是基于“Genairator”的使用，一种专有的基于文丘里管的动态空气注射器，用于产生用于物理搅拌的微泡，并结合了可渗透清洁剂的开发。基本的概念验证研究表明，Genairclean可以在不增加成本的情况下将清洁效率提高高达40%，从而显著提高工厂效率。该技术将应用于海水淡化过程中使用的反渗透和纳滤（NF）膜，包括工业，商业，市政，医疗保健，政府和非营利部门。该方法提供了潜在的革命性的膜化学清洗市场价值6.25亿美元，从而节省。52米/年
