True Eco offers advanced activated carbon solutions designed to meet the growing demand for high-performance gas and water purification across a wide range of industries. Our systems leverage both physical and chemical adsorption mechanisms to remove pollutants with high efficiency and reliability.

 

​Physical Adsorption: Powerful Molecular Capture Capability:

 

Activated carbon is a highly effective adsorbent used across a broad range of industries for the purification of air, water, and industrial effluents. Its exceptional physical adsorption performance comes from its extensive internal pore structure, offering a massive surface area of 1,000–1,500 m² per gram. . This porous network enables activated carbon to trap a wide range of contaminants through van der Waals forces, a non-reactive and reversible mechanism.

​

In air purification, activated carbon effectively removes volatile organic compounds (VOCs), odours, and other airborne pollutants. In wastewater treatment, it targets dissolved organics, pharmaceutical residues, pesticides, dyes, and heavy metals, which diffuse into the pores and adhere to the carbon surface without undergoing chemical change.

​

One of the key advantages of physical adsorption is its reusability. With thermal regeneration or pressure swing processes, activated carbon can be desorbed and reused—offering a cost-effective and sustainable solution for both air and water applications.

 

Key Advantages:

1. Fast kinetics for high-flow systems.

2. Broad-spectrum pollutant removal across industries.

3. No chemical transformation, simplifying downstream treatment or disposal.

Common Applications

• Municipal Water Treatment: Removes trace organic contaminants and residual disinfectants, delivering clean and safe drinking water.

• Textile Dyeing: Eliminates colorants, surfactants, and organic pollutants from wastewater.

• Pharmaceutical Manufacturing: Purifies process water and treats complex organic residues in effluents.

• Food Processing: Supports decolorization, deodorization, and removal of unwanted organics from both water and product streams.

​

Chemical Adsorption: Deep Purification Through Surface Chemistry

 

Beyond physical adsorption, activated carbon offers a second line of defense: chemical adsorption, enabled by reactive surface functional groups such as:

• Carboxyl (-COOH)

• Phenolic hydroxyl (-C₆H₄-OH)

• Carbonyl, lactone, and quinone groups

These functional groups form strong chemical bonds with certain pollutants, resulting in irreversible adsorption—ideal for removing compounds that cannot be effectively captured by physical means.

This mechanism provides deep purification, especially for reactive organics, acidic gases, and dissolved contaminants in both air and water, for example :

• Carboxyl groups are highly effective in adsorbing acidic organic compounds.

• Phenolic hydroxyl groups show strong affinity for phenolic-type pollutants.

 

By tailoring the surface chemistry of activated carbon, True Eco can deliver targeted solutions for specific gas compositions or wastewater profiles—especially in industries with complex and variable effluents.
