One of the most widely used water filter materials in water filter systems and applications is activated carbon. They're a version of carbon that has porosity, lots and lots of cracks, and has pores down to the size of a few molecules. Normally, activated carbon is utilized for eliminating organic impurities or taking free chlorine out of water. For more ways to tell the activated carbon water filter apart from regular charcoal, see the article below!

What is activated carbon?

Activated carbon water filter (activated carbon) is a carbon (activated whose surface area and porosity have been increased to achieve high adsorption efficiency. Due to this excluded form, the surface of activated carbon is relatively huge, for it has an easy adsorption reaction with a lot of materials. Carbonaceous materials for water treatment can be prepared from carbon-rich matter such as coconut shell, coal, wood, or bamboo by pyrolysis at high temperatures (600-900oC) in anaerobic conditions.

As per GMI Research, the Activated Carbon Filters Market is predicted to expand at a CAGR of 5.1% during the forecast period till 2032

The role of activated carbon in water purificiation

Benefits of using activated carbon to filter water? Activated carbon filtered water is used to eliminate organic compounds (fulvic acid, humic acid, …) or to extract free chlorine from water. The water from there can be drained away, or even used to for example in water purification for production.

The water filtered by activated carbon (AC: activated carbon) cannot remove all impurities including sodium, bacteria, long fluoride, horticulture Nishi, etc.

How does activated carbon filter water?

Activated Carbon- Activated carbon filters are composed of small pieces of carbon (granular or bulk) that have been reduced and are porous with a particularly large surface area. Only 4 grams of active charcoal – that is the surface area of half a football field (6400 square meters) corresponds to this capacity.

As the water passes through the activated charcoal filter, impurities will attach to the carbon, the water then comes out purer. How well it sucks up dirt depends on water flow and temperature. Thus, with low pressure and cold water, smaller diameter activated carbon filters are to be applied.

Coconut shell based activated carbon filters can eliminate contaminants of different size. Activated carbon can also be prepared from wood or coal and sold in forms such as granules or blocks.

Many impurities and chemicals are removed from tap water by cactus camels generated activated carbon. Meanwhile, in the EWG's open letter, he cites studies reported by EPA and NSF that claim that the water purification efficiency of activated carbon is only 60-80% for chemicals and that it reduced as much to 30% for others. The effectiveness of activated carbon water filtration varies depending on the quality and type of material. The EPA (U.S. Environmental Protection Agency) left us a list of all that can be removed using water filters in its safewater program, but the link have been removed.Activated Carbon According to the EPA, activated carbon is the only type of water filtration device that can remove:

Chlorine (Cl)

The majority of tap water in Vietnam is checked, tested, and confirmed safe for daily usage. But chlorine is used to sterilize the water. So you have to get aactivated carbon filter to eliminate chlorine. A high-quality activated carbon filter can reduce as much as 95% of chlorine from your water.

Biological products from chlorine

Biological chlorophenols such as THMs have been recognized as possible carcinogens. Thus, you can filter it from water by passing it through activated carbon. Activated Carbon34 ways EPA – activated carbon can control 32 bio contaminants from chlorine.

Pesticides

Pesticides are substances used to prevent, destroy, or repel plant or animal life that is unwanted, including the organisms that cause bad smells. Carbon water filter,Tested and certified,Activated carbon water filter is tested to remove the most common pesticides including: chlordane, chlordecone (CLD/Kepone), glyphosate (Round-up), heptachlor, lindane, nitrate.

Herbicide

Herbicides are chemicals that are designed to keep weeds from growing in places people don’t want them. It has been proven to remove the most common herbicides2,4-D, atrazine and the maximum reduction of any pesticides.
