Wastewater Treatment Using Nanoparticles

Bapusaheb B. Tambe Patil

Now-a-days the water treatment became the most worried topic all over the world. Increase in the population and industrialization resulting into the contamination of the water (reservoir and ground water). Therefore it is necessary to purify and recycle the industrial as well as the municipal waste water. From last decade the use of nanoparticles for water treatment have gained the special attention due to its property being highly profitable as an adsorbents and for using for filtration purpose. Further the type Magnetic Nanoparticles (MNPs) also possesses the properties like high surface area and being the super-magnetic in nature. The magnetic property of separation is useful by applying external magnetic field to them. Thus the MNPs are also being used for the removal of the toxic heavy metals/ elements like cations, natural organic matter, biological contaminants, and organic pollutants, Nitrates, Fluoride and Arsenic from the contaminated water. The MNPs can be synthesized by various methods like mechanical grinding etc. Among the available different technologies, adsorption by MNPs is one of the best due to its easy handling, low cost and high efficiency. The environmental fate and toxicity of a material are critical issues in materials selection and design for water treatment.
