Nanotechnology for Waste Water treatment and remediation
Contaminated waste water also affects biodiversity and also ecology of the water system. Because waste water contain so many impurities like Organic Dyes, Harmful Microorganisms, Heavy metals etc.. Clean and pure water is basic need for all purposes like for Drinking, Domestic Uses, Industrial Uses etc.
A strong influence of nanochemistry on waste-water treatment, air purification and energy storage devices is to be expected.
Mechanical or chemical methods can be used for effective filtration techniques. One class of filtration techniques is based on the use of membranes with suitable hole sizes, whereby the liquid is pressed through the membrane.
Nanoporous membranes are suitable for a mechanical filtration with extremely small pores smaller than 10 nm ("nanofiltration") and may be composed of nanotubes. Nano filtration is mainly used for the removal of ions or the separation of different fluids.
Nanoparticles are also harmful to biodiversity

Nanotechnology for oil recovery to save Ecosystem and Biodiversity
Oil spills from container ships or offshore platforms are a frequent hazard to marine and coastal ecosystems and an expensive one to clean up. BP expects the Gulf of Mexico oil spill in 2010 -- the worst environmental disaster in U.S. history -- to cost it $40 billion.
On it's own, oil is not magnetic, but MIT researchers say that when mixed with water-repellent nanoparticles that contain iron, the oil can be magnetically separated from the water. The nanoparticles can later be removed to enable the re-use of the oil.
Numerous solutions have been proposed for dealing with the problem of oil spills. These include
Ø Use of microorganisms to digest the oil
Ø Mechanical means like skimmers, booms, pumps, mechanical separators etc.
Ø Sorbents to remove oil from water through adsorption and/or absorption and
Ø Use of chemical dispersants like detergents etc.
Conventional techniques are not adequate to solve the problem of massive oil spills. In recent years, nanotechnology has emerged as a potential source of novel solutions to many of the world's outstanding problems.
Although the application of nanotechnology for oil spill cleanup is still in its nascent stage, it offers great promise for the future. In the last couple of years, there has been particularly growing interest worldwide in exploring ways of finding suitable solutions to clean up oil spills through use of nanomaterials.
Given the unique features of nanomaterials, there is a need for the development and implementation of appropriate and fit for purpose scientific approaches. This philosophy is based on the following:
1) The marine environment is likely to be a sink for nanomaterials as it is for most man-made pollutants; it is therefore possible that certain nanomaterials may bio-accumulate and bio-magnify along the marine trophic chain, thus potentially affecting marine biological resources (wild and farmed);
2) Nanomaterials may be transferred to humans through diet by consumption of contaminated seafood products;
3) Nanomaterials may lead to a deterioration in marine environmental quality (coastal areas including natural and recreational interests) with social and economic repercussions.
4) Some nanomaterials can, however, be used to reduce marine pollution, through selected applications, such as for instance through remediation by binding and removing specific contaminants.
