There are various types of Water filter System that are used extensively for different levels of impure water. Some of these methods have been in use for a long time while others have been derived keeping in mind the growing level of impurities in the water of our supply. Some of the water filter systems are listed below.
One of the oldest methods for water filtration, boiling is known to eliminate any organic and biological organism from the drinking water. Though was useful before, it did not eliminate the inorganic harmful substances.
Also, one of the oldest, this used to eliminate larger inorganic particles by the method of letting the water stay still due to which the particles settle down at the bottom and the water on the surface is pure. This, however, leaves the organic microorganisms in the water.
Activated charcoal is very good for bonding with impurities and settling them on the surface of the charcoal. Because it is pure carbon the possibility of attaching every impurity is far more.
Ozone readily gives up the third oxygen atom due to its unstable nature which proves to be deadly for microorganisms and water borne diseases. This should be made in house and should have bubbly contact with water. It leaves harmful chemicals behind which is why it is rarely used for regular purposes.
- Chlorine Bleach
It is the process of adding choline to the water to avoid water borne diseases. The chlorine eliminates any living organism and ensures safe drinking water. But extreme chlorine can also be dangerous for the health and so it is not used for consumption purposes.
- Activated Carbon Filter
These are granules of the activated charcoal and are used today by every water filter manufacturer in their filter system for eliminating the smell and giving taste to water. It is also used before the purification for making the water suitable for treatment.
- Reverse Osmosis
One of the best methods for filtration discovered yet, reverse osmosis applies the theory of osmotic pressure to eliminate larger impure molecules in the permeable membrane and has been proven to be the most effective form of purification yet.
This is the process of getting fresh water by boiling the seawater and cooling down the vapor. As much as useful this is, it requires a lot of energy and hence is not used on a mass production basis.
- UV Water Filter
This filter is again effective for killing microorganisms. A chamber of water is exposed to UV rays which essentially kills them. However, if the energy dose is not enough, the genetic structure of the organism might change but their biological process will not be disrupted.
- Solar Distillation
This is a good filtration system for people stranded on a lifeboat and is present in every one. It uses the method of distillation but however uses the solar power of the sun to heat because of unavailability of other resources. This makes is good for emergency situations but not effective on a regular basis.’
