Enhancing Environment by Nanotechnology

Abstract

The ecosystem is being poisoned by growing industrialization and urbanisation. Conventional methods are costly and not effective, like filtration, centrifugation and biological treatment. Therefore, innovative and appropriate strategies for environmental monitoring and treatment need to be established. The approach to the above problems is nanotechnology. For waste water treatment, nanoparticles, nanomembranes, nanofilters, and nanocatalysts have been developed. Nanotechnology has the power to manipulate nanoscale matter and thus produces certain materials with unique properties and functions. These have smaller sizes (1-100 nm) and a higher ratio of volume to surface area. The dangerous contaminants could be degraded to the less hazardous component utilizing nanotechnology and the volume of contaminants can also be decreased by reducing the amount of content used in the processing processes. Because of these characteristics, they have more reaction surface, resulting in improved performance and selectivity. With certain challenges resolved, nanotechnology will fix all environmental concerns.
