- COD Reduction and Compliance Support for Wastewater
Content 01Are You Facing COD Compliance Challenges?
- Wastewater COD is close to the discharge standard, and the risk of exceeding the standard remains ongoing.
- Wastewater COD has increased due to higher production volume or changes in raw materials.
AMCON’s Solutions
Centered on the Activated Carbon System for COD Removal, AMCON supports wastewater COD reduction and compliance with discharge standards.
We provide solutions tailored to wastewater characteristics by industry, including treatment of refractory substances at chemical and pharmaceutical plants, COD polishing treatment at food plants, and leachate treatment at final disposal sites.
As one approach to wastewater COD countermeasures, adsorption treatment using the Activated Carbon System for COD Removal is used. COD-causing substances include a wide range of organic and refractory substances. Activated carbon has the ability to adsorb and remove these substances through its pores, and when installed downstream of biological treatment, it is used as a polishing step for refractory COD that cannot be fully broken down by biological treatment.
At AMCON, we measure COD, BOD, SS and other parameters of wastewater samples in-house, confirm whether the activated carbon system is applicable, and provide a treatment plan based on the wastewater characteristics.
Features of the Activated Carbon System for COD Removal
Key Features
- Supports refractory COD: Handles organic matter and color components that are difficult to break down through biological treatment.
- Can be added to existing equipment: Compact configuration that can be integrated downstream of existing flows such as biological treatment.
- Activated carbon selected according to wastewater characteristics: Appropriate activated carbon is selected based on the characteristics of the wastewater.
The type of activated carbon selected, including raw material, particle size and form, varies depending on the substances causing COD in the wastewater. Based on the measurement results of wastewater samples, AMCON recommends activated carbon suited to the application.

Typical Application Patterns for the Activated Carbon System for COD Removal
The following application patterns vary depending on the purpose of installation and the condition of the existing equipment.
When Added Downstream of Biological Treatment
This approach applies to cases such as chemical and pharmaceutical plants or food plants where biological treatment is in place, but refractory COD cannot be fully broken down and COD levels remain close to the standard value. By adding an activated carbon system downstream of the existing biological treatment equipment, the system helps remove refractory COD components as a polishing step.
When Used as Polishing for Leachate Treatment
This approach applies to wastewater that requires long-term COD management, such as leachate from final disposal sites containing refractory organic substances and color components. Combining an activated carbon system downstream of biological treatment or coagulation treatment helps stabilize effluent water quality.
When Added to Strengthen the Treatment Capacity of Existing Equipment
This approach applies when treatment capacity needs to be strengthened without significantly changing the existing wastewater treatment flow, such as in response to tighter regulations, revised discharge standards, or increased load accompanying higher production volume. Adding an activated carbon system downstream helps improve effluent water quality while making use of the existing equipment.

Common Questions
- Can it be added while making use of the existing treatment equipment?
- Yes. The Activated Carbon System for COD Removal can be integrated downstream of existing equipment, so it can be added while making use of the current treatment flow, such as biological treatment.
- Can we request wastewater analysis only?
- Yes. If you provide a wastewater sample, COD, BOD, SS, and other parameters can be analyzed to evaluate the applicability of the Activated Carbon System for COD Removal and provide guidance on possible countermeasures.
- A regulatory value has changed and we need to respond. Can this be handled in a short period of time?
- This depends on the wastewater conditions, the required treatment level and equipment conditions. Depending on urgency, AMCON can provide phased responses such as adding an activated carbon system or improving operation, so please contact us as early as possible.
