Water Purification Technologies

Water purification technologies refer to the various methods used to remove contaminants and impurities from water, making it safe for drinking, industrial use, or other applications. These technologies have evolved significantly over the years, from simple physical processes like filtration and sedimentation to more complex chemical and biological treatment methods.

Reverse Osmosis (RO)​

Reverse osmosis is a popular water purification technology that uses semi-permeable membranes to separate contaminants from water. This process involves applying pressure to force the water through these membranes, which filter out dissolved solids, bacteria, viruses, and other impurities.

Ultraviolet (UV) Light Disinfection​

Ultraviolet light disinfection is an effective method for eliminating bacteria, viruses, and other microorganisms in water. By exposing the water to UV light, this technology can kill a wide range of pathogens, making it a popular choice for municipal and industrial water treatment systems.

Advanced Oxidation Processes (AOPs)​

Advanced oxidation processes involve the use of strong oxidizing agents like ozone or hydrogen peroxide to break down organic contaminants in water. These agents react with pollutants, transforming them into harmless compounds that can be easily removed from the water through further treatment steps.

Nanofiltration and Microfiltration​

Nanofiltration and microfiltration are membrane-based technologies that use tiny pores to filter out impurities from water. While they are not as effective at removing dissolved solids like reverse osmosis, these methods can be useful for treating a wide range of contaminants, including bacteria, viruses, and particulate matter.

Solar Disinfection​

Solar disinfection is an innovative method for purifying water using sunlight. By placing contaminated water in a clear container and exposing it to direct sunlight, this technology can kill pathogens through UV radiation, making it a low-cost solution for communities with limited access to clean drinking water.
