Technology Overview

Demand for Clean Water Drives Advances in Water and Wastewater Treatment

With the rising need for clean water and subsequent increase in generation of wastewater, it has become mandatory to treat wastewater in order to obtain high-quality pure water. Nanotechnology is generally used in areas where there is a need for attacking the molecular level of the substances. "Various forms of nanotechnology such as, nanomembranes and nanoporous zeolites are being used for the treatment of water and wastewater," according to the analyst of the study. "Though the pace of advancement of nanotechnology has been slow with respect to water and wastewater treatment, industrialists are researching various kinds of nanotechnology to effectively treat water and wastewater."

The primary motive for wastewater treatment is that less than 1 percent of the world’s water is suitable for drinking while the remaining is brackish. As a result, there is a growing need for fresh and clean water especially for drinking purposes. This escalates the need for technologies that produce high quality water after treatment that do not cause any detrimental effect to human beings or the environment. Utilizing nanotechnology for water and wastewater treatment would certainly make previously unusable water sources such as brackish water, seawater, and other wastewater as an available source of water supply.

Multiple Benefits of Nanotechnology Encourages Widespread Uptake in Water and Wastewater Treatment

The quality of water that is obtained after the adoption of nanotechnology is well within the requirements of agencies such as Environmental Protection Agency (EPA). It has been determined that these nano-based filters are able to achieve 99.95 percent efficiency, when compared to conventional technologies. As a result, the water or effluent that is obtained after the treatment could be reused for various domestic and industrial applications.

Nanotechnology even removes protozoan cysts, oocysts, and helminth ova and in some cases bacteria and viruses from the water. "Nanotechnology also provides more effective alternatives to the treatment of contaminants such as mercury, arsenic, and perchlorate," explains the analyst. "As the impact of these contaminants on humans is gradually realized, it has become increasingly essential to monitor them at trace levels, which is impossible with conventional treatment methods."
