Activated carbon is a material or material that has very many and wide pores. These pores function as absorbents of contaminants that pass through them. That is, if the water is filtered with activated carbon, the contaminants in the water can enter the pores and be retained in them. In this case, if the numbers are made, as much as 450 grams of activated carbon can contain about 40 hectares of surface area.
Ways of working
Activated carbon works by absorption. That is, when there is a material that passes through the activated carbon, the material contained in it will be absorbed. So do not be surprised if this material is able to remove some of the content that is not good from polluted water. It can indeed clear up cloudy water while removing the unpleasant odor from the water.
To make activated carbon, you can use several materials. Among them are;
- Material from animals
- Material from plants
- Coconut shell
- Shell or hazelnut shell
- Coconut shell or skin
- Bones, etc
Many natural ingredients are used to make activated carbon. After all, the latest technology/innovation can also find ways to make activated carbon using certain chemicals.
The function of activated carbon in water filters can clearly be felt by people in big cities, especially those who have been using waterways, both simple and mechanical / technological. Some of the benefits provided by activated carbon for drains and water purifiers are;
First, get rid of the smell
Smelling well water will be treated with activated carbon or activated charcoal. This material is used in some water purification products.
Second, purify the water
Turbid water can also be overcome by utilizing activated carbon. In particular, by utilizing expansive pores to resist sedimentation or deposits contained in the water.
Third, releasing chlorine
Chlorine in water can be absorbed by activated carbon. In this way, it is considered safe to provide drinking water that is suitable for consumption.
Fourth, create a fresh taste in water
Water that tastes bland and unpleasant can be overcome with activated carbon. In this case, activated carbon can create a fresh taste in the water.
Fifth, non-absorbable material
Although many contaminants can be absorbed, it turns out that activated carbon can also pass some water substances, including minerals, salts, and inorganic compounds.
Therefore, the use of activated carbon in waterways must be collaborated with other innovations to remove contaminants that cannot be absorbed by it.
Carbon filtration is a filtration strategy that uses an activated carbon to remove contaminants and impurities, using chemical adsorption. Each piece of carbon is designed to supply a large portion of the surface zone, to allow the most likely presentation of contaminants to the filter media. One pound (454g) of activated carbon contains a surface area of approximately 100 hectares (1 km²/kg) This carbon is mostly positively charged and decomposed to attract negatively charged water contaminants.
