Overview of Different Water Filtration Techniques - check'em out!

If you have access to clean drinking water, you may not want to take it for granted. Nowadays, over 2 billion people cannot access clean drinking water. What this means is that they don't have clean water to cover their routine needs such as cooking food, washing their hands, taking a shower, washing their clothes, doing their dishes, and so on.

In the United States, most homes receive filtered water. At the same time, many homeowners still feel the need to treat the municipal supply water. They want to filter out potential contaminants, foul tastes and smells. This problem is due to unfiltered chemicals in the water.

If you want to install a water filtration system, we suggest that you understand various filtration techniques. If you have this type of information on your mind, you can go for the ideal system.

Understand the Difference Between Chemical and Physical Filtration

Primarily, there are two major kinds of water filtration techniques: physical and chemical. When it comes to physical filtration, water is sent through a strainer in order to eliminate large impurities and particles. On the other hand, chemical filtration refers to a process of passing the water via a material that contains an active chemical ingredient. In this case, different methods are used.

Water Filtration Techniques

Nowadays, people use different types of water filtration methods. Given below is a description of some of these:


In this method, water is heated up to remove impurities and then collect the condensed water in different types of containers. This method is an ideal choice if you want to remove sodium, nitrates, lead, dissolved solids, and bacteria from your drinking water. However, it may not be a good choice if you want to remove volatile organic compounds like pesticides and herbicides.

Reverse osmosis:

In this method, water is passed through an affective semipermeable membrane at high pressure. This type of membrane filters out heavy contaminants and impurities. After the filtration stage, water is collected in a container.

An RO filter uses a lot of energy, but it is a great choice if you want to remove chemical compounds from your drinking water. Some good members of these compounds include nitrate, sulfate, arsenic, chromium, lead, sodium, copper, and chloride. In some reverse osmosis units, you may find additional filters that can help filter out organic compounds and different types of contaminants.

Activated carbon:

This type of filter is on the list of most popular techniques as far as home water filtration is concerned. The good thing about this type of filter is that it is porous. In other words, its functions like a sponge to remove impurities such as industrial solvents, pesticides, and Chemicals. However, you cannot use this method to soften your hard water or filter out heavy metal contamination.

Ion exchange:

This type of method is the best choice if you want to soften your hard water. In this process, contaminants in the water are split up at the ionic level. Afterward, all of the impurities are trapped and released. You can use Ion Exchange with a reverse osmosis unit in order to filter out sodium levels.

UV filtration:

In this method, ultraviolet light is used in order to eliminate viruses, parasites, and bacteria. However, you cannot use these devices in order to eliminate minerals.
