How Water Filtration Works

Water, among all other necessities for human survival, is also abundantly available on our planet. But that doesn’t mean that all the water you find on the surface of the Earth is drinkable or safe.

As most know, water happens to be a universal solvent and can absorb practically anything. This property of water makes it very unsuitable for drinking.

You actually have no idea where your water is coming from, or exactly how safe it is. When pollution levels are on such a hike, and there has been a significant increase in the types of diseases faced by us, there is no time to be lost.

Water filtration provides the perfect system in which you can receive safe, clear, hygienic, and potable water at low costs. The initial installation cost may be high, but in all other terms, these systems pay for themselves through the years, many times over.

Water filtration solves all these problems for you at the minimum cost and low maintenance level. Today, technological advancements and developments have taken this business far into the future, with amazing customizations and designer products.

Usually, water filtration works in the following ways:

Activated Carbon Filtering:

This basically involves filtering water with the help of activated carbon granules (usually charcoal). They absorb most of the impurities and this results in clearer water that can be used for drinking and other purposes.

Although, activated carbon filtering has one minor issue. It does not remove the hardness of water that comes from the presence of some heavy metals in the water itself.

Reverse Osmosis:

It refers to the process where water is forced through a membrane in such a way that the impurities remain behind. This gives us access to clearer and more hygienic drinking water.

Ion Exchange:

Filters that use ion exchange process have spare sodium ions in them. When hard water enters the purifier it usually contains magnesium and carbonate compounds, which eventually split into magnesium and carbonate ions inside the filter. The filter beads find magnesium and carbonate ions more attractive than the already present sodium ions. An exchange of ions takes place, which not only makes the water “soft” but also tastier.


Some filters use the process of distillation to purify water. Water is set to boil and then the steam is collected and condensed into the liquid state again. This process may reduce the hardness of water considerably and also separate water from all other major impurities. The only problem faced by this method of water filtration is that some of the volatile impurities may still remain in the condensed water.

Water can be purified or filtered by various techniques. The major plus of water filtration is that you do not have to worry about serious illnesses like cholera or typhoid. Water is an important substance, required for human sustenance.

Since we cannot do without it, it is only befitting that we take the help of science and technology to use it wisely and with precaution. Water filtration is now an essential part of our lives and should be made available to all.
