Activated Carbon

As a leading water treatment materials manufacturer with 28 years of experience, we supply high-quality activated carbon and complete water treatment solutions to customers worldwide. Thanks to its strong adsorption capacity, activated carbon is widely used in drinking water purification, industrial wastewater treatment, air purification, and chemical decolorization. This guide aims to help users choose and apply activated carbon more effectively.

Types of Activated Carbon

Coconut Shell Activated Carbon :High hardness, strong adsorption; ideal for drinking water, food processing, and pharmaceuticals.

Coal-Based Granular/Pellet Activated Carbon : High mechanical strength and long lifespan; widely used in industrial gas treatment and wastewater pretreatment.

Powdered Activated Carbon :Fast adsorption; suitable for emergency treatment, decolorization, and odor removal.

How to Select Activated Carbon for Different Industries

1. Drinking Water & Surface Water

Recommended: Coconut Shell Activated Carbon
Reason: Efficient removal of organic matter, odor, taste, and residual chlorine.

2. Chemical Industry Wastewater

Recommended: Coal-Based Granular Activated Carbon
Reason: Strong durability for continuous adsorption towers.

3. Food, Pharmaceutical, and Sugar Decolorization

Recommended: Powdered Activated Carbon
Reason: Rapid adsorption and high decolorization efficiency.

4. Electroplating & Metal Industry Wastewater

Recommended: High-iodine value granular activated carbon
Reason: Effective removal of heavy metals and complex organics.

How to Use Activated Carbon

1. Fixed-bed continuous adsorption
Suitable for large-scale industrial treatment.

2. Mixing and dosing (for PAC powder)
Used for emergency treatment and decolorization.

3. Activated carbon filters
Ideal for drinking water and circulating water systems.

Avoid common mistakes:

    ● Do not apply in strong acid/alkaline water

    ● Do not use with oxidants like sodium hypochlorite

    ● Avoid overdosing

Storage and Handling Guidelines

    ● Store in a cool, dry, ventilated place

    ● Keep away from moisture and contaminants

    ● Use promptly after opening

    ● Avoid dust and open flames for powdered carbon

FAQ

Q1: How often should activated carbon be replaced?

Every 3–6 months depending on system load and water quality.

Q2: Can activated carbon be regenerated?

Granular activated carbon can be regenerated; powdered carbon typically cannot.

Q3: How to choose between powdered and granular activated carbon?

Powdered carbon for emergency or decolorization; granular carbon for continuous filtration.

Q4: Why does water become turbid after using activated carbon?

Improper use or insufficient filtration may cause carbon particles to remain in the water.
