Dear Mohammad Hooshmandzadeh ,

I think the pdf i am providing here will be beneficial for you as it is well explained in it about the effects of nanotechnology and potential environmental effects of nanotechnology which also covers the economic advantage.

• The impact of nanotechnology on the development of tools and techniques for water treatment will be more pronounced in the near future. As scarcity of natural water threatens the advancement and the social security of many communities around the world, it is expected that the solution will emerge from the exploitation of nanoparticles to make water recycling, seawater desalination and water remediation more efficient and cost effective.
• The advantages of using nanofiltration relied in the direct humanitarian benefit from using nanotechnology and in the promotion of economical viabilities in rural communities. Therefore, the production of nanostructures, nanocomposites and modified nanostrucutres for water remediation will increase because of the need for producing clean water in fast and low energy consumption ways. Nanotechnology should be regarded as the tool to ensure the sustainability of social communities in different places.

I'd be interested in any listing of nanomaterials at present used in water treatment processes. Not speculation or potential, but actual applications presently used.

Nanotechnology has significant and vital role in Wastewater and water management process. In addition, utilizing this high tech approach can cause obvious decrease in end prices concerning mentioned process.

OK, Ali Faghfouri Please list one application or material in the nanotechnology field at present used in waste water treatment.
