Why Activated Carbon is used for Water Purification? 

Carbon has been used in our lifestyle for a very long time and has infinite positive aspects. If you are searching for the Uses of Activated Carbon in the water purification process then you have come to the right place. Here, you will find "Why is activated carbon used for water purification?"

What is Activated Carbon

Activated carbon is a type of carbon that is frequently used to filter impurities from water and air, among many other uses. It does so with such effectiveness that it is the most widely used purifying agent. It has been treated to have tiny, low-volume pores, increasing the amount of surface area open to adsorption. Usually, activated carbon is made from waste materials like peat, coal, wood, coconut shells, etc.

What is Activated Carbon used for?

Active Carbon is used in many different applications including the preparation of food and beverages, removing odours, reducing industrial pollutants, purifying drinking water, and more.

Before answering why activated carbon is used for water purification, let's discuss how carbon filters work. Carbon filters act as barriers by removing contaminants from your drinking water. The amount of contamination that activated carbon removes from the or water depends on many different factors, including the type and amount of pollution, types of activated carbon, the acidity and temperature of the water, and how long the water spends in contact with the activated carbon.

Why is Activated Carbon Used for Water Treatment?

Carbon filters work on a principle called adsorption. In simple words, carbon attracts impurities to its surface and cleans the water and makes it fit for drinking.

A carbon filter acts as a parking lot with pores for parking spaces for contaminants as water flows through. The tiny pores are measured in microns. The smaller the micron, the finer the filtration. Low flow rate and pressure give contaminants more time to park or adhere to the carbon. The more contact time water has with the surface of a carbon filter, the more efficient the filtration.

Types of Activated Carbon

There are many types of Activated Carbons produced in the market. Different manufacturers produce different types of activated carbon. Most common types of activated carbon are Granular Activated Carbon (GAC), Powdered Activated Carbon (PAC), Extruded Activated Carbon (EAC), Impregnated Carbon, Bead Activated Carbon (BAC), Woven Carbon, Polymer Activated Carbon, etc. You can find more information on types of activated carbon here.

Uses of Activated Carbon

Activated Carbon has over 2,500 commercial products used in some capacity. The majority of wastewater treatment facilities employ carbons to clean the air and water. Activated Carbon is an inert solid adsorbent material, frequently used to treat gas-phase streams and remove a variety of dissolved pollutants from water. Due to its unique properties, activated carbon has an excellent capacity to remove dissolved pollutants from water, such as species that enhance flavour, odour, colour, or toxicity. Through adsorption processes based on surface interactions between pollutants and carbon graphitic platelet surfaces, removal is accomplished.

What does activated carbon remove from water

Activated carbon filters reduce a vast number of impurities in drinking water. Swift Green Filters has filters made by renowned scientists globally that use activated carbon to reduce 300+ contaminants from water including:

  • CTOs: CTOs refers to chlorine, taste and odour that manipulates the taste and odour of the water.

  • VOCs: VOCs are the organic compounds that makes the water impure and harmful for drinking

  • Heavy Metals: Heavy metals present in water are arsenic, lead, mercury, copper, etc. and consuming them is dangerous for your liver, kidney, intestines and can even cause cancer. 

  • Herbicides & Pesticides: Herbicides & Pesticides get mixed in water by seepage of contaminated surface water, improper disposal, etc. 

  • Fluoride: Fluoride is one of the most important toxicological environmental hazards globally and can cause neurological side effects. 

  • Pharmaceuticals: Pharmaceuticals mixed in water are dangerous for both aquatic as well as human life. It gets into the water supply via human excretion and by drugs being flushed down the toilets.

  • Viruses: Viruses are harmful for the body as it can cause headaches, diarrhoea, nausea, etc. 

  • Chemical Compounds: Some chemical compounds are dangerous for the human body. It gets into water by industrial discharge, urban activities, etc. It causes skeletal issues, kidney cancer, testicular cancer, etc. 

  • Microplastics: Microplastics are minuscule fibres of acrylic, nylon, spandex, polyester and can cause oxidative stress, DNA damage and inflammation if consumed by humans. 

  • Swift Green Filters makes Refrigerator Water Filters, Commercial Water Filters, Under-sink Water Filters and Pitcher Water Filters that are capable of removing above-mentioned harmful contaminants from water.

    So, we came to know why activated carbon is used for water purification. It makes the water cleaner. Moreover, there is 0% wastage of water if you use Swift Green Water Filters for your residential or commercial needs. The water from the activated carbon filters contains healthy minerals and has unlimited goodness. You can browse a wide range of carbon block filters including refrigerator water filters, under sink water filters, pitcher water filters and custom carbon blocks. All these water filters are well certified by IAPMO to meet NSF/ANSI standards.
