Water is essential for our livelihood. We can go without food for several days, but a day without water can really take a toll our body. A few days without water and we’re as good as dead. Water is life. It’s as simple as that. Even our bones, contain 25% of water. On an average, we require about 2 litres of water to keep our bodies functioning at it’s very best. With water being so important, we have to make sure that the water we consume is clean, fresh and pure.
Our environment is filled with billions of micro-organisms and bacteria. This also means that if we take water from an unfiltered source, it’s bound to be infested with micro organisms that aren’t suitable for our body. Many of us fall sick when we consume water that is unfiltered.
And this is how the idea of a water filtration system came into existence. Sceintists and engineers worked hard to create a compact system to ensure that the water we drink is pure and clean. Eventually, this system was installed in various schools, hospitals and homes, leading people to safe drinking water and keeping our bodies healthy.
How were they made? How do they work? What’s inside that filters the water and makes it suitable for us to consume?
We’re here to asnwer all these questions for you.
Water has a wondeful molecular structure that tends to dissolve things. You can mix a lot of things in water and it tends to dissolve instantly. This is useful for the many things that we do in our day to day lives, from washing clothes to making tea. But it also has a downside.
Since water is excellent at dissolving, it dissovles dirt and impurities as well.
Hence, water filters were made in a manner to remove the impurities that dissolve in water as well as remove big chunks of dirt or impurities found in water.
Water filters basically use two different techniques to remove dirt.
Physical filtration – Where water is physically filtered i.e. by straining to remove large impurities through large or small sieves.
Chemical filtration – Here, water passes through an active material that removes impurities chemically as they pass through for the smaller impurities that cannot be seen.
There are four types of water filters.
Activated Carbon Granules
This is usually seen in many household and domestic settings. Activated carbon granules are well known for attracting impurities and trapping them. This causes the water to be filtered and gets rid of many impurities. But activated carbon doesn’t last long and has to consistently be replaced.
When water is forced through a very fine fitler with a lot of pressure, the water passes through but the contaminants remain behind. Reverse osmosis requires energy to push water with a lot of force. Which is why electicity or any other form of energy is used to filter water. This process usually makes water suitable for consumption.
Ion-exchange filters are used soften water by removing limescale (a hard white substance consisting chiefly of calcium carbonate).
These filters were designed to split contaminating substances to make ions (electrically charged atoms with electrons). Then they trap those ions and exchange “bad” ions for “good” ones. This results in clear, uncontaminated water.
One of the simplest ways to purify water is to boil it, but even though it get’s rid of many different kinds of bacteria, it doesn’t remove chemicals, limescale, and other contaminants. This is where distillation is useful. Distillation goes a step further than ordinary boiling.
Distillation is the process of separating the substances from water by using selective boiling and condensation that gets rid of a lot of impurities.
Different types of filtrations remove different contaminants—but there’s no particular technique that removes all the contaminants. This is the reason why most filtration systems use two or more processes together inorder to provide pure and safe drinking water.
If you do not have a water filtration system, require to renew one or install it for other purposes, you’re welcome to go through our website. Our products contain RO and UV Filtration systems that give you safe drinking water that is afforable and gurantees health.
