Products Description
Acid-washed activated carbon is made from high-quality coal activated carbon or coconut shell activated carbon, which is acid-washed. The product is mainly made from granular carbon, which is acid washed during the manufacturing process to remove unwanted impurities, resulting in a product with very low acid soluble iron content.
Ideal for many liquid phase applications, acid-washed granular activated carbon is specifically designed to purify water and organic liquids that require low ash and leachate content. Its superior hardness levels and low levels of impurities make it cleaner than most other carbons and give it a longer service life.

The core application of acid-washed activated carbon is efficient adsorption and purification, especially excelling in applications requiring high purity and low impurities. Through the acid washing process, it reduces heavy metals and ash content, enhancing adsorption performance. Its main applications include:
1. Drinking Water Purification
Function: Removes residual chlorine, odors, organic pollutants (such as chloroform), and heavy metals, improving water quality and taste.
Applications: Pre-filter units in reverse osmosis water purification systems, filter cartridges in household water purifiers.
2. Industrial Wastewater Treatment
Function: Purifies water quality, removing residual chlorine, odors, and organic pollutants.
Applications: Filled in filters, filter cartridges, or filter elements in water treatment equipment.
3. Food and Beverage Processing
Function: Removes pigments and odors, ensuring product quality and safety.
Applications: Decolorization and refining of sugar solutions, fruit juices, and other food products.
4. Pharmaceutical Field
Function: Used for decolorization, purification, and toxin adsorption of pharmaceuticals.
Applications: Used as a secondary purification medium in blood purification equipment.
5. Air Purification
Function: Adsorbs volatile organic compounds (VOCs) such as formaldehyde and benzene from the air.
Applications: Air purification in newly renovated homes, industrial waste gas treatment.
6. Other Applications
Gas Masks: Adsorb toxic vapors.
Battery Applications: Used as a catalyst carrier.
Acid-washed activated carbon significantly improves adsorption performance by reducing impurities and adjusting pH, making it the preferred material in many demanding fields.
