Activated carbon plays a crucial role in sewage and wastewater treatment, as it can efficiently remove organic pollutants, odors, heavy metals, and harmful chemicals. Sewage treatment activated carbon is specially designed for high adsorption efficiency, durability, and stability in harsh industrial and municipal wastewater conditions.

"(《世界人权宣言》) Sewage Treatment Activated Carbon Making Machine is industrial equipment that converts raw materials like coconut shells, coal, bamboo, wood, or agricultural residues into activated carbon suitable for wastewater purification.

What is a Sewage Treatment Activated Carbon Making Machine?

A Sewage Treatment Activated Carbon Making Machine is specialized equipment designed to produce activated carbon optimized for wastewater treatment. Unlike general-purpose activated carbon, sewage treatment carbon requires:

• High adsorption capacity
• Low impurity content
• Resistance to water flow and chemical environments
• Uniform particle size

The machine integrates:

• Carbonization
• Activation (steam or chemical)
• Screening and granulation
• Cooling and packaging

Raw Materials for Sewage Treatment Activated Carbon

Common feedstocks include:

• Coconut shells – microporous and high hardness
• Coal – anthracite or bituminous coal for high carbon content
• Bamboo – renewable biomass with good mesopores
• Wood – produces moderate-density activated carbon for water treatment
• Agricultural residues – e.g., palm shells, nutshells, rice husk

Pre-treatment:

1. Crushing to uniform particle size
2. Drying to reduce moisture
3. Screening to remove impurities

Working Principle of Sewage Treatment Activated Carbon Making Machine

Step 1: Crushing and Drying

Raw materials are crushed into small particles and dried to moisture below 10%, preparing them for efficient carbonization.

Step 2: Carbonization

Crushed material is fed into a carbonization furnace or rotary kiln. Heated in low-oxygen conditions, volatile components are released, leaving behind carbon-rich char suitable for activation.

Step 3: Activation

• Steam Activation – high-temperature steam reacts with carbon char, forming micropores.
• Chemical Activation – chemicals like KOH, ZnCl₂, or H₃PO₄ are used to create a high-surface-area, high-adsorption carbon.

Step 4: Screening and Granulation

Activated carbon is screened to ensure uniform particle size. Granulation or pelletization can be applied depending on the application in wastewater treatment systems.

Step 5: Cooling and Packaging

Activated carbon is cooled, stabilized, and packaged for industrial or municipal wastewater applications.
