Abstract:
Water is life. It is a precondition for human, animal and plant life as well as an indispensable resource for the economy. As freshwater becomes increasingly rare due to population growth, urbanization, the use of wastewater increased to overcome this problem. wastewater is not just sewage .all the water used in the home that that goes down the drains or into the sewage collection system is wastewater .pollutants of the wastewater include heavy metals, inorganic waste and organic waste. Different techniques as physical, chemical and biological treatment processes have been developed for the removal of organic matter from polluted water stream.
In general, physical treatment processes are one of these techniques which separate the waste streams by either applying physical forces or changing the physical form of the waste from the process. the adsorption technique is one of the most frequently applied technologies for the removal of inorganic and organic compounds from aqueous solution. Using Nano adsorbents has some advantages over using other adsorbents because of their high specific surface area to volume ratio.
