Adsorbent-based nanotechnologies have been shown to remove various toxic contaminants from water rapidly and efficiently to acceptable levels. The major benefit of this nanotechnology is that it does not generate brines or other toxic disinfectant byproducts like other water treatment methods. Currently, point-of-use commercial membrane filters available in the marketplace are not capable of simultaneous inactivation of microorganisms and removal of heavy metals. This project presents an inexpensive and easy method to prepare membranes capable of removing heavy metals and inactivate microorganisms in water at an affordable price. The proposed technology has economical and societal benefits since this water purification system is portable, multi-functional, and presents a low fabrication cost. This technology has the potential to be applied in industrial, military, and domestic settings. Furthermore, this technology, successful, could help improve water quality availability worldwide and relieve water-related diseases that kill more than three million people in the world every year.

已经证明，基于吸附剂的纳米技术可以快速有效地从水中清除各种有毒污染物至可接受的水平。这种纳米技术的主要好处是，它不会产生盐水或其他有毒的消毒剂副产品，而不是其他水处理方法。目前，市场上可用的商业膜过滤器无法同时灭活微生物和去除重金属。该项目提出了一种廉价，简便的方法，可以准备能够以可承受的价格在水中清除重金属和灭活微生物的膜。拟议的技术具有经济和社会利益，因为该净水系统具有便携式，多功能，并且呈现出较低的制造成本。该技术有可能应用于工业，军事和国内环境。此外，这项技术成功，可以帮助改善全球水质的供应，并减轻与水有关的疾病，每年杀死世界上超过300万人。
