WHAT IS CARBON ACTIVATED?

Activated carbons are made from carbon materials such as coconut shells, wood, brown coal, anthracite coal, bituminous coal through activation process to create micro pores with molecular sizes on surfaces, which become adsorption media having inner surface area more than 1,000m²/gram.

TYPES OF ACTIVATED CARBONS

• CLASSIFICATION BY PHYSICAL PROPERTIES
• Powder, grinding, pills, cylindrical form, global, spherical form, fibre, etc.
• CLASSIFICATION BY RAW MATERIALS
• Plants: coconut shell, wood, sawdust, charcoal, etc.
• Coal: bituminous coal, anthracite coal, brown coal, mud coal, etc.
• Petroleum: petroleum deposit, petroleum carbon
• Others: paper pulp, synthetic plastics, organics

CLASSIFICATION BY ACTIVATION METHODS

• Activation methods by gas, chemicals, combination of gas and chemicals, etc.

APPLICATIONS OF ACTIVATED CARBON

APPLICATION OF GASEOUS ADSORPTION

1. Air pollution prevention

• Adsorption of VOCs
• Exhaust gas purification
• De-dioxin
• De-Sox, De-NOx
• Rejection of air pollution substances

2. Deodorization/odor removal from factory, sewerage treatment
3. Gaseous filter/gaseous filtering machine to prevent toxic substances
4. Recovery of useful materials: car canister and solvents, etc.

APPLICATION OF LIQUID ADSORPTION

1. Application in purified water, fresh water, tap water (water treatment plant)
2. Removal of organic substances in water, purified water for households, business bases, industries and water filtering machine
3. Domestic and industrial wastewater treatment
4. Cleaning for food industry: sugar, milk, food oil, food additives, etc.
5. Dilution process in chemical industry and other industries: pharmaceutical industry, emulsion, rubber products, petroleum, polymer, inorganic chemicals, mining, etc.
6. Liquid adsorption: drug, food, gas, iodine, etc.
