Nanoscience has great potential for water purification, which can be a solution for increasing clean water resources. In this project our goal is to design a new water filtration system that is less costly, and sustainable.
The recent report entitled 'Water for People - Water for Life' of the UNESCO says that 1.1 billion people lack access to improved water supply and 2.4 billion lack access to improved sanitation. t is also stated, that water-related diseases have affected a large amount of the population. Recent advances strongly advocate that the use of nanotecnology based water-treatment systems have potential to reduce water related diseases, and other water quality problems. However, water purifying nanoscience technologies are often complicated, and are expensive to run and maintain.
According to Gehrke, I., Geiser, A., & Somborn-Schulz, A. ,the adaptation of highly advanced nanotechnology to traditional process engineering offers new opportunities in technological developments for advanced water and wastewater technology processes. (Gehrke, Geiser, Somborn-Schulz, 2015)
On the other hand,Fostering Nanotechnology to Address Global Challenges: Water report, which published by OECD states that the unknown impacts of nano-particles properties lies at the core of the ongoing health and safety concerns regarding the use of nanoparticles, including in water processing and treatment. (Fostering Nanotechnology to Address Global Challenges: Water, 2011, p35)
Das, Hamid, Ramakrishna, and Chowdhury highlighted that the lack of cost-effective water purification technology has already aggravated the crisis of clean water and safe water for the rapidly growing population. The authors also point out that this issue which mentioned above, extremely serious and has been posing a big treat to global health, economic growth, sustainability ans social progress. (Das, Hamid,Ramakrishna, and Chowdhury, 2014, p 98)

Among many potential applications, carbon nanotubes (CNTs) are great candidate materials for cleaning polluted water. CNTs are made of carbon, only a few nanometers across CNT membranes can remove almost all kinds of water contaminants.
We, as an imaginative innovation researchers' team, suggest that the new technique which uses CNTs for cleaning polluted water could provide a simple answer to the problem of huge costs. Our empirical data will show that CNTs, which are improved by our methods are potentially efficient adsorbents for a variety of pollutants in both drinking and environmental waters. The process will be also really well to protect public from nanotechnology risks.
