200 & 325 Mesh Wood-Based Powdered Activated Carbon for Citric Acid Purification

Product Specification

200 & 325 Mesh Wood Based Powder Activated Carbon for Citric Acid Purification

Product Introduction

Wood-based powdered activated carbon is specifically formulated for the purification and decolorization of citric acid solutions during fermentation and crystallization processes. It effectively removes pigments, fermentation by-products, residual organics, and metal ions, resulting in a bright, high-purity citric acid product.

Produced from selected hardwood raw materials under strictly controlled carbonization and activation conditions, this activated carbon offers a well-developed pore structure and large surface area tailored for liquid-phase adsorption. Two grades are available to meet diverse process requirements:

• 200 Mesh: Standard grade for general purification lines with balanced adsorption and filtration performance.

• 325 Mesh: Fine-grade option recommended for export-grade or high-color citric acid production lines requiring superior clarity and low turbidity.

Note: Specifications and particle sizes can be customized according to customer requirements.

Features· 

• High Decolorization Efficiency: Removes fermentation pigments and yellow-brown organic residues, ensuring high optical brightness of citric acid crystals.

• Selective Adsorption: Effectively adsorbs color bodies and impurities without reducing citric acid yield.

• Two Mesh Grades:

  • 200 Mesh: Optimal flow rate and filtration balance for conventional production lines.

  • 325 Mesh: Enhanced surface area and microporosity for high-color or export-grade citric acid purification.

• Low Ash and Heavy Metal Content: Ensures product purity and prevents ionic contamination in downstream crystallization.

• Consistent Batch Quality: Produced under strict process control for uniform performance in repeated purification cycles.

Applications

• Citric Acid Refining: Decolorization and purification of fermentation liquor before concentration and crystallization.

• Organic Acid Production: Applicable to malic acid, tartaric acid, and lactic acid purification processes.

• Food & Beverage Ingredients: Used in refining edible acids to meet international color and purity standards.

• Pharmaceutical and Biochemical Industries: Ensures high-purity organic acid intermediates for drug synthesis and biochemical applications.

Manufacturing Process

• Premium Wood Feedstock: Made from renewable hardwood sawdust with low mineral content and uniform texture.

• Controlled Carbonization: Precisely carbonized to preserve structural integrity of pores for high adsorption performance.

• Steam or Chemical Activation: Activation process tuned for optimal micropore distribution in liquid-phase purification.

• Multi-Stage Washing: Acid-washed and thoroughly rinsed to remove residual ash and ensure chemical neutrality.

• Rigorous Quality Testing: Each batch tested for adsorption capacity, pH, ash, and heavy metal levels to ensure consistency and compliance with food-grade standards.

Packaging Options

• 25kg Bags: Multi-layer kraft paper bags with PE inner liner for moisture protection, suitable for general use.

• 500kg Jumbo Bags: Designed for large-scale production lines requiring continuous feed operations.

• Customized Packaging: Available upon request to match customer logistics or automated dosing systems.
