What are the Conventional Water Filtration Methods?

Whether a home water filtration system or an industrial filtration system for effective production, everywhere, a preferred method is instilled to channel, remove the impurities from the water and purify it. However, each method has its own pros and cons. Generally, you can find the best filtration system according to your requirement and befitting use. Hence, before selecting the filtration system, you should be aware of the conventional water filtration methods imbibed in them. Now, let’s dive into the list of water filtration methods.

  1. Reverse Osmosis

Reverse osmosis-based systems are highly versatile, practical and involve the naturally occurring process. They are well-considered in the water treatment by removing fluoride, dissolved salts, sodium, and bacteria. The minute pores abundance and availability in the semi-permeable membrane within the reverse osmosis water purification system are very small in preventing most bacteria from passing through the membrane. As per the stats, it is observed that more than 95 percent of dissolved contaminants are removed from the water. However, prolonged use of these filters loses their effectiveness and requires replacing. They are known for providing good quality of water, although they are more expensive than other water filtration methods.

  1. Activated carbon filters

The mechanism of activated carbon water filtration systems is by binding toxins in the water. It essentially entraps the pollutants and contaminants to purify water. Further, these filters are befitting for the chlorine and other chemicals in the water. Besides this, to enhance the quality of water even more, activated carbon filters are combined with other water filtration techniques. The distinguished property of this activated carbon filter is that it has a long life with yearly replacement.

  1. UV Sterilization filters

UV sterilization is one of the most effectual methods to purify contaminated water and destroy the bacteria and microbes present in it. The primary purpose of these filters is to kill the bacteria, viruses, and protozoa which are present in the water, making it perfect for drinking purposes.

  1. Solar-powered water filters

These filters run by the inexhaustible energies of nature i.e., sun. Typically, they operate with the help of the sun’s natural energy. This energy is captured in the solar panels, and then it is converted into usable energy. These type of water filters comes in handy for outdoor activities such as camping.

Even the maintenance of many solar-powered water filters is simple, as they don’t need batteries. Moreover, these filters don’t mainly need heavy cleaning; they are environment friendly and require only sunlight for their application.


You will be astonished to know that there are few water filters that remove fluoride from the water, and some refrigerator filter systems combined with activated carbon filters don’t eliminate any fluoride as a result; a simple total dissolved solids (TDS) test is required. A TDS meter is a small instrument that measures the conductivity of the water, which are available in abundance due to the presence of dissolved ionized salts and minerals. Hence, these are some of the filtration methods used in the home water filtration systems or in the industries.
