There are numerous bacterias along with viruses and parasites found in water that could cause severe illness. The risk can be minimized by filtering the water to capture and eliminate these harmful organisms.
Water filtration involves a variety of methods that include chemical, physical, and biological processes. Reverse osmosis is by far the most widely used method for water filtering. It is an impermeable membrane to filter out contaminants and particles. Another option is distillation which boils water to separate from contaminants, and later converts the vapor back to liquid.
Physical filtration is a process that makes use of physical barriers in order to get rid of particles from water. This can include sediment filters, activated carbon filters, as well as other kinds of filters. Sediment filtering works by capturing particles inside a screen, or filtering medium. activated carbon filters utilize activated carbon to remove pollutants.
Chemical filtration is a method which uses chemical to eliminate pollutants from water. This is done using ultraviolet light, chlorine and ozone. Chlorine is commonly employed to treat water for disinfection in the same way that ozone and ultraviolet light can be used to eliminate the microorganisms as well as other pollutants.
