Currently nanotechnology plays a vital role in water purification techniques. Nanotechnology is the process of manipulating atoms on a nanoscale. [1] In nanotechnology, nanomembranes are used with the purpose of softening the water and removal of contaminants such as physical, biological and chemical contaminants. There are a variety of ...
Applications of nanotechnology – Uses for technology on very small scales; Nanomaterials – Materials whose granular size lies between 1 and 100 nm; Nanotechnology – Technology with features near one nanometer; Ultrafiltration – Filtration by force through a semipermeable membrane; Reverse osmosis – Water purification process
Nanoremediation has been most widely used for groundwater treatment, with additional extensive research in wastewater treatment. [5] [8] [9] [10] Nanoremediation has also been tested for soil and sediment cleanup. [11] Even more preliminary research is exploring the use of nanoparticles to remove toxic materials from gases. [12]
Nanotechnology offers the potential of novel nanomaterials for the treatment of surface water, groundwater, wastewater, and other environmental materials contaminated by toxic metal ions, organic and inorganic solutes, and microorganisms. Due to their unique activity toward recalcitrant contaminants, many nanomaterials are under active research ...
These chelating groups hold tightly onto Hg (II) ions, removing it from the water. When purifying mercury from sea water, a decrease in the volume to surface area ratio leads to a decline in the efficiency of the elimination.7 Cost efficiency of the nanotrap process is indicated in the fact that the materials can be reused to recycle more water.
In tandem with nano-scale particulate, studies have demonstrated CNTs can cause damage to microbial cell walls and kill bacteria. [ 9 ] [ 10 ] Single-walled nanotubes tend to exhibit more antimicrobial behavior than multi-walled and double-walled nanotubes and inhibits the formation of biofilms, the first stage of biological fouling.
A product called AMRIT, meaning elixir in Indian languages, developed by the Indian Institute of Technology Madras, is an affordable water purification technology based on advanced materials, which has been validated through research articles [52] [53] and patents [54] and has been approved for national implementation in India. The technology ...
Li studies water contamination and treatment. She joined the faculty at Rice University in 2006. [4] The research of the Li laboratory for Advanced Water Treatment Technologies includes analysis of how membranes become fouled during filtration, how to remove salt from seawater and how to use nanotechnology to clean water.
