There are hardly any homes that do not use water filters. This is because the water we use today may not be exactly suitable for drinking. This is the case even with filtered metro-water and other sources of water coming from the local authorities. There are many homes that depend on water that is drawn out from the ground and here the chances of impurities and harmful substances are quite high. However, a single treatment method may not be able to remove all the impurities, chemicals, and harmful materials. We will look at the various chemicals and impurities that need to be removed. This will give you an idea about the kind of water filters that you would require particularly when it comes to removing lead from water.
We need to bear in mind that there are two ways in which water filters perform their task. One is physical filtration and the next one is chemical or active filtration. Quality water filters use a combination of the above two techniques to ensure the best of filtering. Active filtering changes the contaminants and makes it ineffective while physical filtering actually filters out the water. Therefore, by using a combination of both, it is possible to ensure that the water is completely pure from all sorts of impurities.
Filtration For Removing Silt, Sediment And Sand
This is one of the most common and primary tasks of any bi-carbonate filter system. When buying a filter you must make sure that it removes silt, sediment, and sand which are often considered as naturally occurring pure dirt. However, unless these sediments are removed it would not be possible for the water filters to do the critical task of active filtration. This is basically done by the reverse osmosis technology. If the water is impure and has sand and other solid particles in it, it could block the reverse osmosis devices and the entire filtration could come to a grinding halt. This process includes filtering of heavy metals like lead.
The Function Of Chemical Filters
The function of active filters or chemical filters is to ensure that the ions and chemicals and soluble minerals are completely removed from the water. This includes removal of chemicals like magnesium, chlorine, fluoride, and other such impurities. It also helps in killing harmful bacteria, viruses and other contaminants that could lead to illness and sickness of the body. Many modern-day filters also use ultraviolet rays to ensure total and 100% destruction of harmful viruses and bacteria that might have escaped the reverse osmosis process. However, there are a few who feel that too much use of ultraviolet rays could lead to health challenges and the debate still continues.
Which Water Filter To Use
As mentioned earlier, it may not be possible to have a straight-jacketed approach as far as water filters are concerned. Different water sources and different locations might call for different types of water filters. Some ground might have excess deposits of fluoride and other such chemicals and in such cases, you need to have a different approach rather than going in for the usual approach. The job is best handled by professionals who carry with them the right experience and expertise.
