Activated Carbon for Water Treatment-Heycarbons Manufacturer From China
Heycarbons is an acivated carbon supplier for water treatment, ensuring drinking water safety, compliant production water use, and compliance of industrial wastewater discharge standards.
Water is an essential resource for human survival, industrial production, and the functioning of ecosystems. Water in nature usually contains impurities before being used for drinking or other purposes and needs to be treated to meet safety requirements; while wastewater generated during industrial production contains a variety of pollutants, and direct discharge without treatment will pollute the environment.
Therefore, both the use of natural water and the discharge of industrial wastewater require purification through water treatment processes. Activated carbon, due to its excellent adsorption properties, is widely used in water treatment.
Why is Activated Carbon Used for Water Purification?
Through carbonization and high-temperature steam activation processes, activated carbon possesses a huge specific surface area and a well-developed pore structure, which can adsorb organic pollutants, odor substances, residual chlorine, etc. in the water into the interior of the pores, thereby improving water quality.
Activated carbon can adsorb a wide variety of substances, both organic and inorganic, ionic and non-ionic. In addition, the surface of activated carbon can also act as a catalyst, so it can be used in many different applications.
Therefore, activated carbon has a wide range of applications in water and wastewater treatment.
How does Activated Carbon Filter Water?
When the water to be treated passes through the activated carbon filter layer, the pollutants in the water come into contact with the surface of the activated carbon.
The large specific surface area and well-developed pore structure of activated carbon provide abundant adsorption sites for pollutant molecules, enabling them to accumulate and be retained on the surface and inside the pores of activated carbon.
How does Activated Carbon Work in Water Purification?
Once pollutants enter the pores, they are immobilized by various forces, including physical adsorption and chemical adsorption:
- Physical adsorption: Adsorbs organic matter and odor substances through intermolecular forces;
- Chemical adsorption: Activated carbon surface functional groups react chemically with some pollutants.
Activated carbon can effectively remove various pollutants such as odors, residual chlorine, and organic pollutants, thus purifying water.
It’s important to note that activated carbon is not a resource that can be used indefinitely. Once the adsorption sites are gradually filled, adsorption saturation occurs, and the purification effect decreases. Therefore, it needs to be replaced or regenerated periodically.
Heycarbons Activated Carbon for Water Treatment Products
Coal-based granular, coconut shell granular, and powdered activated carbons are popular choices for water, drinking water, and wastewater treatment. This is due to their effective contaminant removal, proven track record in engineering applications, reliable operational stability, and low usage costs.
Coal Granular Activated Carbon for Water Purification
Coal-based granular activated carbon (crushed raw coal and briquetted carbon) is the choice of the majority of customers. It can effectively adsorb pollutants such as BOD, COD, odors, pigments, chloramines, organic acids, esters, phenols, fluoride, cyanides, and halogenated hydrocarbons from water. Can also be used for water filtration in water treatment plants, community water stations, and well water systems.
The specification of coal granular activated carbon in the table below are provided for reference.

Coconut Shell Granular Activated Carbon for Water Treatment
Coconut shell activated carbon has developed micropores and is generally not used for wastewater with pollutants of medium or larger pore sizes, but is mainly used for the fine, advanced purification of drinking water.
Currently, due to international market conditions, the price of coconut shell carbon is high. Cheaper nutshell activated carbon can be used as a substitute, yielding equally good results.
Common mesh sizes for coconut shell/nutshell activated carbon used in water treatment are: 10*20, 8*30, 12*40, etc.
Powdered Activated Carbon for Water Treatment
The use of coal-based powdered activated carbon is also a common solution in wastewater treatment. Compared to granular activated carbon derived from coal, powdered activated carbon is more suitable for short-term enhanced treatment or emergency water treatment scenarios due to its flexible dosing methods and faster mass transfer rates.
The specifications for the coal powdered activated carbon are as follows:
- Mesh size: 100, 200, 325, etc.
- Iodine value: 500-1100 mg/g
- Methylene blue: 120-150mg/g
- Ash: ≤8-20%
- PH: 8-11

What does Activated Carbon Remove from Water?
Activated carbon adsorbs organic substances.
Activated carbon has a strong adsorption capacity for dissolved organic matter in water, and it also has a good adsorption capacity for some organic pollutants that are difficult to remove from water by biological or chemical methods, such as herbicides, pesticides, detergents, synthetic dyes, amine compounds, and many other artificially synthesized organic compounds.
In wastewater treatment, activated carbon adsorption is usually placed after biological treatment, which is called activated carbon tertiary wastewater treatment. This is to further reduce the organic matter content in the wastewater and remove pollutants that are not easily decomposed by microorganisms, so as to meet discharge requirements or achieve the purpose of closed-loop circulation.
Activated carbon has a very strong ability to adsorb organic matter. In tertiary wastewater treatment, each gram of activated carbon can adsorb several tens of percent of its own weight in COD. Adding tertiary treatment to a wastewater treatment plant can achieve a BOD removal rate of 95%. With appropriate desorption methods, valuable substances in the water can also be recovered. For specific desorption or carbon regeneration procedures, please contact Heycarbons.
Adding powdered activated carbon to aeration equipment can improve treatment efficiency beyond typical secondary biological treatment methods, producing effluent quality close to that of tertiary treatment. Furthermore, it can make the activated carbon sludge denser and more compact, reducing effluent turbidity and increasing the hydraulic load of secondary treatment.
What is Activated Carbon Used for in Water Treatment?
Activated carbon can be used to remove pollutants at extremely low concentrations in water, as well as odors and trace amounts of harmful substances from tap water. Granular activated carbon (GAC) is an effective means of removing organic matter, odors (usually from residual chlorine, sulfides, VOCs, etc.), and especially synthetic organic matter (SOCs) from water.

Activated carbon adsorbs inorganic substances.
Many inorganic substances are also adsorbed by activated carbon. For example, activated carbon can effectively remove halogens. In water treatment, excessive chlorine is often added to kill bacteria and remove organic matter from the water to ensure the smooth progress of coagulation and filtration processes.
Activated carbon has a greater capacity for removing bromine than for removing chlorine. It can also strongly adsorb free iodine and potassium triiodide in water, but unlike chlorine and bromine, it does not react with carbon. Therefore, activated carbon can be used to recover iodine from water.
Activated carbon can also adsorb fluoride in water. In the production of high-purity industrial water, activated carbon adsorption is often used as a pretreatment before ion exchange to remove harmful substances such as organic matter, colloidal substances, and microorganisms from the water, so as to protect the ion exchange resin and ensure the purity of the effluent.
Activated Carbon Catalyst
Similar to the chemical industry, activated carbon is sometimes used as a catalyst in water treatment. Carbon can adsorb cyanide in water. If air or oxygen is introduced into the influent of an activated carbon adsorption bed, the carbon can act as a catalyst, oxidizing the toxic cyanide into non-toxic cyanate and improving the cyanide removal efficiency.
If you need to treat cyanide-containing wastewater, Heycarbons can help you customize an activated carbon solution.
In addition
In addition, activated carbon is used in wastewater treatment to remove trace amounts of Hg(II) (in the μg range). When combined with biodegradation technology, it can remove trace agricultural chemicals, organohalides and rust from water. It can also remove ammonia, amines, H2S and aldehydes from wastewater.
