Home Introduction to water purification

Ensuring that your household or domestic water supply is clean for use, cannot be done without some form of water purification unit. Unwanted compounds, debris, and bacteria from organic and inorganic materials can cause illnesses for members of a household, if these contaminants are not removed from the supply. Through various channels, these impurities can find their way into the water supply that serves your home. The public water supply can become contaminated while in transit even though tremendous effort is placed in the treatment and conditioning of water at public water facilities run by municipal authorities. Public water systems can carry germs and hazardous parasites, before distribution to residential homes in urban areas; this is the main challenge faced by water treatment facilities. Water borne diseases caused by protozoan water bacteria causes more sicknesses or serious illnesses than any other form of bacterial based pollutant. A water purification using RO membranes can easily remove contaminants from water using modern filtration technologies.

Depending on the water source, homeowners can remove simple impurities such as debris from their water to suspected contaminants such as soluble gases or viruses using the right filtration and purification technology. Homes that are supplied with water from private sources can also make use of filtration units or a water purification based on RO just as well. Reverse osmosis is often the principle technique used in the purification of feed water. Hundreds of purification systems produced today rely on this technology to function. A wide range of pollutants can be removed effectively through reverse osmosis which at times makes it more comparatively more expensive than other purification systems. Other technologies, such as activated carbon are often used in purification systems as well. However, they do not filter near as many impurities as reverse osmosis does. It would be more cost effective to seek out a carbon based filtering system if after conducting a water analysis test you find only pollutants and impurities that can be readily removed from the water supply using this method. Particles that are greater than 0.5 microns are easily removed by activated carbon purification systems. Activated carbon is very popular among homeowners because it is easy to replace during scheduled maintenance and lower in relative cost. Particles that are smaller than 0.5 microns on the other hand, fall within the domain of reverse osmosis filtration units which are a preferable choice. Through reverse osmosis and or ultra violet water treatment, bacteria and protozoa are usually removed. If you are looking for a comprehensive solution for your entire household that will purify and filter against the widest possible range of contaminants then a water purification that uses at least two of the popular technologies, is preferred. In doing so, an activated carbon filter can remove the larger contaminants that would otherwise damage the more sensitive reverse osmosis membrane, while the reverse osmosis membrane can be used solely in the removal of microscopic contaminants that are between 0.0005 and 0.005 microns in size. For added peace of mind, if the unit has a UV filter as well, you will be able to neutralize any biological contaminants that may still be in the water after filtration. It is a sure way to guarantee the success of the purification process.
