Pure water is nothing but two molecules of hydrogen and one of oxygen. Add anything else to it and it is not pure anymore. That certainly does not mean that it is not good quality water. Water is said to be of bad quality when it has undesirable additives in it. These could be physical, chemical or biological in nature. Changing the quality of water requires the removal of these contaminants and this process requires water purification.
A water purifier has become essential in all homes. The purification required could certainly be simply because the quality of water available varies from place to place as the source of water varies. Depending on the contaminants present in the water, the purification process also varies from simple to complex. What is it that you need for your home to get good quality water? To ascertain this, you need to first find out what the water contains.
Undissolved Physical Contaminants
These include suspended impurities such as mud, sand, silt, clay and other sediments. These make the water murky and certainly unpalatable to drink just by its appearance. The good news is that the purification required for such water is simple. Gravity-based water filters are good enough if this is the only kind of impurity present in the water. When present with other impurities, a higher level of water purification is required.
Dissolved Physical Contaminants
Natural salts and minerals tend to get dissolved in underground water. While some quantity of these is desirable in water, it tends to become harder and not fit for drinking when they exceed the prescribed limit. The quantity of these dissolved salts needs to be brought down and this can be done through reverse osmosis purification. This process helps to remove all the salts from the water and even the required minerals get removed during the process. Since this can be harmful, thus, some water filters use a TDS controller to ensure that the water retains the minimum quantity of minerals thereby making it healthy.
Other Dissolved Chemicals
Some industrial waste also gets dissolved in the water and results in a change of taste and odour. In particular, radioactive waste can be highly dangerous for consumption by living beings. Chemical impurities in water include acids and organic & inorganic compounds. These are certainly not a desirable component of drinking water and need to be removed through chemical treatment in water plants. These chemicals affect the pH level of water. Pure water is neither acidic nor basic with a pH level of 7. For drinking water, it must be in the range of 6.5 – 8.5.
The presence of microorganisms such as algae, protozoa, bacteria, viruses etc. in the water is also not desirable as they are the cause of several illnesses. If these are present in your water supply, you will need to treat it with UV rays, also known as ultraviolet water purification. These kill the microorganisms, but to remove them, you will require ultra-filtration.
If you wish to improve the quality of your drinking water, you need to rely on a variety of purification methods. Getting a suitable water purifier home must be a priority if you value the health of your loved ones.
