The activated carbon filter relies on the well-developed pore structure and large specific surface area of activated carbon to adsorb residual chlorine, organic pollutants, color, and odorous substances in water, and can also serve as a pretreatment unit for residual chlorine removal and organic matter reduction.
Process Principle
- Physical adsorption: relies on van der Waals forces to concentrate organic molecules on the surface of activated carbon micropores.
- Catalytic reduction: the activated carbon surface can catalytically reduce free chlorine to chloride ions, achieving dechlorination.
- After adsorption saturation, adsorption capacity is restored by replacing the filter media or regeneration; effluent parameters need to be monitored regularly.
Product Features
- Simultaneously removes residual chlorine, color, odor, and some organic matter, providing both protection and purification.
- It has good adsorption performance for macromolecular and hydrophobic organic matter and can reduce the risk of organic fouling in downstream membranes.
- Filter media replacement and backwashing are simple, with low operation and maintenance difficulty.
- It can be combined with filter media such as quartz sand and manganese sand to form a multi-layer filter bed and expand removal functions.
Application Industries
- Feedwater dechlorination and organic matter reduction for reverse osmosis and ion-exchange systems.
- Decolorization and odor removal treatment for drinking water, food and beverage water, and pharmaceutical water.
- Advanced treatment of industrial wastewater and pretreatment before reuse.
- Removal of odorous gases and trace organic pollutants in water bodies.
