Activated carbon in water treatment and purification

Filter media are granulated or powdered materials that allow the passage of raw water through them by retaining the particulate matter. Filter media are selected based on desired physical characteristics, such as specific size, gravity and particle sizes that will define the degree and efficiency of the filtration.

In KEIKEN, we supply quality filtering media, suitable for each application in wastewater treatment and water purification. In addition, we maintain exclusivity agreements with manufacturers around the world, which allow us to have an unbeatable quality of the product and with a very competitive price.

In this post we will focus on the Activated Carbon as a filter media in the treatment and purification of water.

ACTIVATED CARBON

Activated Carbon is a highly adsorbent filtering medium with high carbon content and a high internal porosity, and therefore a large free surface for adsorption. An example of active charcoal that we supply in KEIKEN would be the one coming from the coconut husk. The active charcoal of coconut husk (vegetable) is made from coconut shell, is a material that are characterized by having a large amount of pores and a high hardness.

ACTIVATED CARBON IN WATER TREATMENT

Activated Carbon has a high adsorption capacity of a wide range of contaminants including aromatic compounds, hydrocarbons, detergents, pesticides, soluble dyes, chlorinated solvents, phenols and derivatives of hydroxyl groups.
Adsorption is a process where a solid is used to remove a water soluble substance. In this process the active carbon is the solid.
They are an ideal choice for use as a tertiary treatment with a view to water reuse. They are also very effective in the elimination of toxic compounds that can jeopardize the functioning of the biological treatment, improving, in turn, its performance.

Activated Carbon Wastewater treatment systems are easy to implant and maintain, as they can even be incorporated into conventional purification systems.
From KEIKEN we can offer our experience and versatility in offering a filter media and Activated Carbon of exceptional quality at a very competitive price. Do not hesitate and request more information at info@keiken.es.

FAQs

1. Why is activated charcoal used to treat drinking water? 

Activated charcoal is an extremely porous form of carbon with exceptional abilities to absorb contaminants. Due to its ability to remove chemicals, odors, colours, and organic compounds by "trapping" them within its structure, it has become one of the most common methods for water treatment.

2. How do activated carbon filters clean drinking water?

Activated carbon removes pollutants from water by adsorption; the pollutants adhere to the surface of the activated carbon particles. The porosity and high surface area of activated carbon enable it to attract and retain a wide range of substances, including chlorine, pesticides and volatile organic compounds.

3. What types of activated carbon are available for drinking water purification? 

Granular activated carbon (GAC), powdered activated carbon (PAC) and coconut shell-derived activated carbon are the most common types. Due to its high strength and superior ability to adsorb contaminants compared to other types of activated carbon, coconut shell carbon has become one of the most popular forms of activated carbon for use in filtration media.

4. Is activated charcoal effective in treating wastewater? 

Yes. Activated charcoal has been shown to be highly effective in treating wastewater, particularly in the tertiary stages of treatment. Activated charcoal can be used to remove residual contaminants, toxic chemicals and organic compounds from wastewater, allowing it to be safely reused.

5. How often should activated carbon filters be changed? 

The frequency at which activated carbon filters should be replaced depends on the quality of the incoming water and how much water is used, but in general, filters in smaller systems need to be changed every three to six months.
