Powder Activated Carbon for Wastewater Treatment

With the accelerating pace of industrial development and urbanization, the wastewater treatment industry faces increasingly complex water quality challenges. Whether it's chemical wastewater, dyeing and printing wastewater, pharmaceutical wastewater, or advanced municipal wastewater treatment, many pollutants are difficult to completely remove using traditional biochemical or physicochemical processes. These include dissolved organic matter (DOC/TOC), recalcitrant organic matter, color, odor, and trace pollutants (such as pesticide residues and drug residues).

In these processes, powdered coal-based activated carbon (PAC) has become an important material for improving effluent quality in wastewater treatment due to its high adsorption capacity, good dispersibility, and economic efficiency.
activated carbon for waste water

As a professional activated carbon manufacturer, Zhulin Activated Carbon provides high-quality powdered coal-based activated carbon suitable for various wastewater treatment processes, including advanced treatment, decolorization, deodorization, and COD degradation.

Why is powdered coal-based activated carbon used in wastewater treatment?

1. High Adsorption Capacity: Exhibits strong adsorption capacity for anionic/nonionic organic compounds such as color, phenols, aromatic hydrocarbons, and surfactants.
2. Good Dispersibility and Fast Reaction Rate: The fine powdered activated carbon particles mix thoroughly in water, improving adsorption efficiency.
3. Particularly Effective for Recalcitrant Pollutants: Suitable for deep purification of industrial wastewater, such as in the pharmaceutical, printing and dyeing, agrochemical, and petrochemical industries.
4. Enhances the Stability of Biochemical Systems: Adsorbs toxic substances, reduces inhibition of microorganisms, and improves the treatment performance of biochemical tanks.
5. Flexible Operation: Dosage can be adjusted according to pollutant fluctuations, providing significant effectiveness in emergency treatment.

Powder activated carbon application for wastewater

Powdered activated carbon (PAC) is widely used in the following processes:
• Deep Polishing: Used to further reduce COD and TOC, bringing water quality up to discharge or reuse standards.
• Decolorization: Particularly suitable for dark or persistently colored wastewater such as dyeing and printing wastewater, chemical wastewater, and food processing wastewater.
• Odor Removal and Sensory Improvement:
• Combined with Coagulation Processes: The combination of PAC and flocculants (such as PAC/polyferric sulfate/PAM) is often used to improve overall treatment efficiency.
• MBR/Biochemical System Stabilizer: Removes toxic substances, improves sludge activity, and reduces shock loads.
