What is pac activated carbon?
Overview of pac activated carbon:
PAC activated carbon is a refined material made from selected sources such as sawdust, coconut shell, fruit shells, or coal. It undergoes a meticulous process of fine screening, drying, mixing, and soaking. This material is activated through physical or chemical methods, resulting in micrometer-sized particles, a highly porous structure, and exceptional adsorption capabilities. Compared to granular activated carbon, it has a smaller particle size and a higher specific surface area, making it more effective in adsorbing organic pollutants in water, removing odors, decolorizing, purifying gases, and eliminating heavy metal ions.
Applications of pac activated carbon:
PAC activated carbon is a crucial material widely used in wastewater treatment, chemical and pharmaceutical industries, air purification, and the food and beverage sector. Its primary function is to remove trace pollutants from water, thereby improving water quality. Due to its efficient adsorption capabilities and eco-friendly nature, powdered activated carbon has a broad application prospect in environmental protection and purification. Studies show that powdered activated carbon of different particle sizes exhibits excellent adsorption properties for organic compounds like aniline, with its specific surface area closely related to the saturation adsorption capacity for organic substances.
Key Characteristics of pac activated carbon:
- High Adsorption Efficiency: The microporous structure provides a high adsorption capacity, enabling quick removal of pollutants from wastewater and improving treatment efficiency.
- Broad Applicability: Not limited by the type of wastewater or the characteristics of pollutants, it can effectively remove a variety of contaminants.
- Flexible Use: Can be used as an independent treatment unit or in combination with other treatment technologies to enhance overall treatment effectiveness.
- Easy to Regenerate: Through thermal or chemical regeneration, powdered activated carbon can be reused, reducing treatment costs.
- Eco-friendly Material: As a non-toxic and harmless environmental material, its use does not cause secondary pollution to the environment.
Wastewater Treatment Process with pac activated carbon:
The application of pac activated carbon in wastewater treatment includes the following steps:
- Pre-treatment: Adjust the pH of the raw wastewater, remove large particle impurities, and create suitable conditions for activated carbon adsorption.
- Addition of Powdered Activated Carbon: Select an appropriate amount of activated carbon based on the characteristics of the wastewater and treatment requirements, and evenly disperse it using mixing equipment.
- Adsorption Process: Under suitable conditions, powdered activated carbon reacts with pollutants in the wastewater to remove them.
- Solid-Liquid Separation: Use methods such as sedimentation, filtration, or centrifugation to separate the powdered activated carbon that has adsorbed pollutants from the water.
- Regeneration and Disposal of Activated Carbon: its adsorption performance or dispose of it safely according to environmental regulations.
Performance Analysis of pac activated carbon:
