Activated Carbon for Decolorization
What Is Decolorization with Activated Carbon?
Decolorization is a process that uses activated carbon’s high internal surface area to selectively adsorb organic compounds responsible for coloration. The porous network of carbon captures these chromophoric molecules, reducing unwanted hues while retaining the essential chemical integrity of the treated liquid.
At Oozechem, we provide tailored solutions as an Activated Carbon Supplier in UAE and Gulf, delivering high performance grades designed for Food decolorization application in UAE
Why Choose Our Activated Carbon?
Superior Raw Material
Our carbon is derived from renewable, wood based precursors, which yields a structure rich in macropores and mesopores. This makes it especially effective for binding highmolecular weight color causing compounds.
Chemical Activation Technique
We use phosphoric acid activation, which optimizes pore development and maintains structural integrity. This activation method enhances adsorption capacity under slightly acidic to neutral conditions, improving efficiency in typical decolorization systems.
Controlled Physicochemical Characteristics
- High iodine number (indicating large surface area and strong adsorption potentia
- Low ash content and high apparent density, making handling and dosing easier
- Reproducible pore structure for consistent performance across batches
How the Decolorization Process Works?
Static Contact Method
- Mix the colored liquid with our powdered or granular carbon.
- Allow sufficient contact time so that the carbon adsorbs the chromophoric compounds.
- Filter out the spent carbon to yield a decolored effluent.
Continuous Column Adsorption
- The liquid flows through a fixed bed column packed with carbon.
- Process parameters such as pH, temperature, contact time, and carbon type are optimized to maximize adsorption performance.
- Once capacity is exhausted, the carbon can be regenerated thermally or replaced.
Key Process Parameters
To maximize performance and cost efficiency, Oozechem helps clients fine tune:
- pH: Slightly acidic tends to enhance adsorption of many pigments
- Temperature: Moderate ranges help maintain kinetics while preserving molecular stability
- Dosage Accuracy: Precise carbon dosing ensures full utilization of adsorption capacity
- Contact Time / Kinetics: Optimizing residence to balance throughput and removal efficiency
- Carbon Type: Choosing between powdered (fast kinetics) and granular (lower pressure drop)
- Column Design: Engineering fixed bed designs to support flow rate and regeneration
Benefits of Using Our Activated Carbon
- High Adsorption Efficiency: Strong affinity for large color causing molecules thanks to our engineered pore network
- Selective Performance: Targets chromophores without significantly affecting other desirable compounds
- Operational Stability: Low ash, high density, and reproducible structure reduce process variability
- Sustainability : Use of renewable wood feedstock and availability of recycled / reactivated carbon reduces environmental impact
- Regenerability: Our carbon can be reactivated thermally, enabling multiple cycles and reducing overall cost
