We've been going on and on lecturing you about how important it is to have a clear source of water at home. Not only will it benefit you, but the whole family's health and safety as well. Now that you truly know the benefits of having your own water purifier at home, let us take you through a quick 101 on the different types of water filtration systems. By understanding how each one works, you will be able to identify what kind of water dispenser you need, and trim down your options to just a few.
- Carbon Filtering
Carbon filtration is used to remove organic compounds and residual disinfectants in your potable water. Aside from eradicating health hazards, this method also removes unpleasant odors caused by chlorine and improves the overall taste of your water. Carbon filtration uses the process of chemical adsorption, whereby a piece of carbon is provided to facilitate chemical attraction. When a certain chemical passes through this carbon surface, it sticks to it and get trapped, which then results to purer water.
One of the oldest method of water filtration is distillation. This process uses heat source in order to vaporise water. First, water is heated until it reaches boiling point and starts to evaporate. For continuous vaporisation, the temperature is kept at a constant, while ensuring water contaminants don’t evaporate together with the pure ones. After then, evaporated water is removed from the heat source and guided to another container. This is the part where it goes back to its original liquid form. The whole process eliminates most bacteria, viruses, and other chemicals that have higher boiling point than your water and makes it pure.
- Reverse Osmosis
Reverse osmosis is one of the most popularly used filtration systems today. To help you better understand this method, allow us to take you through a crash course in Science.
Osmosis: It is a naturally occurring process wherein less concentrated solutions have the tendency to migrate to a higher concentrated solution.
Semi-permeable membrane: It is a layer which only allows a few molecules to pass through.
Now that you know what these two terms mean, we can now discuss reverse osmosis. As the name suggests, this method is just osmosis in reverse. As mentioned, osmosis happens as a natural phenomenon without the need for forced energy. Reverse osmosis on the other hand requires pressure on the higher concentrated solution—which might contain dissolved solids, chlorine, fluoride, microorganisms and heavy metals—to facilitate filtration through the semi-permeable membrane. Reverse osmosis results to demineralisation and deionisation.
- UV Filtration
This is another effective method to purify your water for drinking. UV filtration treatment enables elimination of bacteria and other microorganisms from your water by exposing it to UV radiation. This process causes a disruption to these unwanted particles’ DNA and cripples their ability to further reproduce.
These filtering systems may sound a little too complicated because of its differences in the process of purifying your water, but they are all just centered in one goal—to give you a safe and healthy drinking water. Now that you have a better understanding of how water filtration systems work, you have a better knowledge of what you want to look for in a water purifier.
