COD Remover

COD Remover

Product Overview

COD Remover (also known as COD Reduction Agent) is a newly developed chemical specifically designed to address the difficulty of removing COD (Chemical Oxygen Demand) from wastewater generated by industries such as electroplating, spraying, dyeing, and papermaking. It is highly effective in reducing COD levels and is suitable for treating wastewater with high, medium, or low COD concentrations.

Performance Specifications

Product Applications

Currently, most industrial wastewater is treated through the process:
Neutralization → Coagulation Reaction → Flocculation & Sedimentation → Discharge.
However, this conventional process alone often fails to reduce COD to compliant levels. This COD Remover has been specifically developed to address this issue. When added to wastewater, it rapidly reduces COD levels.

• Water-soluble powder

• Provides excellent COD removal performance

Usage Instructions

• Applicable pH Range: 5–14

• Preparation: Dissolve in a dosing tank to a concentration of 10–20%, stir well.

• Application: Use a dosing pump to add the solution into the reaction tank.

• Optimal pH: Neutral to slightly acidic

• Dosage: Approx. 0.5–1 kg per ton of wastewater (exact amount varies depending on COD level; laboratory testing is recommended for accurate dosage).

Lab Testing Procedure:

1. Take a sample of the wastewater.

2. Add an appropriate amount of COD Remover.

3. Stir for 15 seconds.

4. Add appropriate amounts of PAFCS (Polymeric Aluminum Ferric Chloride Sulfate) and PAM (Polyacrylamide) as flocculants.

5. Allow flocculation and sedimentation.

6. Measure COD to determine effective dosage.

Packaging & Storage

• Packaging: Kraft paper bags with plastic liners inside.

• Storage & Transport:

  • Handle with care; avoid exposure to sunlight and rain.

  • Strictly avoid mixing with acidic substances, reducing agents, flammable materials, and alcohols.
