COD Removal Using Oil-Absorbent Materials in Wastewater Treatment

Enhanced Treatment of High-Concentration Oil Wastewater using Natural COD Adsorbent KC-100

 

In the process of wastewater treatment, selecting the appropriate adsorption material is crucial. Activated carbon and oil adsorbents are commonly used for treating oily wastewater, yet they may vary in terms of effectiveness, cost, and operational aspects. Let's compare the characteristics and performance of these two materials in wastewater treatment!

 

• Characteristics:

​

1. Activated Carbon: Activated carbon boasts excellent adsorption capabilities due to its highly porous structure and extensive surface area. It effectively removes organic pollutants, dyes, and chlorine from wastewater. The wide applicability of activated carbon makes it an ideal choice for treating various pollutants in wastewater. Oil
2. Adsorbents: Oil adsorbents are specifically designed to remove oil-based contaminants from wastewater. These materials rapidly adsorb and immobilize oil, effectively reducing oil content in wastewater. Oil adsorbents often possess good buoyancy, making it convenient to collect and remove oil residues from water.

 

• Performance:

​

1. Activated Carbon: Activated carbon excels in removing organic pollutants, but its performance may be limited when treating high-concentration oil wastewater. Handling a large volume of oil requires a significant adsorption surface area. Therefore, additional processing steps or more activated carbon may be needed to treat high-concentration oil pollution effectively.
2. Oil Adsorbents: Oil adsorbents exhibit high efficiency in removing oil-based contaminants from wastewater. They swiftly adsorb and immobilize oil, effectively reducing oil content. For treating high-concentration oil pollution, oil adsorbents are generally more suitable, enabling efficient oil collection and treatment.

 

• Cost and Operation:

​

1. Activated Carbon: Activated carbon is often costlier, especially when dealing with substantial wastewater volumes requiring large amounts of activated carbon. Additionally, the operation and regeneration processes of activated carbon might demand special equipment and longer timeframes.
2. Oil Adsorbents: Oil adsorbents are relatively cost-effective and simple to use. They can easily collect and remove oil residues from water and can undergo straightforward treatment or regeneration.

 

• Conclusion: ​​

 

​​Based on the wastewater characteristics and requirements, one can choose between activated carbon and oil adsorbents as outlined in the comparison above. Activated carbon suits a wide range of organic pollutant removal, while oil adsorbents are more appropriate for treating high-concentration oil wastewater. Considerations regarding cost and operation should also factor into the selection process. The ultimate product choice should be based on specific needs and evaluations to achieve optimal wastewater treatment results.

Introducing KC-100 COD Adsorbent: We currently offer a COD adsorbent named KC-100, a natural and sustainable modified softwood pellet. It possesses hydrophobic properties and outstanding capabilities for absorbing carbohydrates and oil. Lightweight and easy to handle, it significantly reduces the cost of oil pollution treatment and remains buoyant on the water surface even after saturation.

 

Laboratory Data Sharing: Below are laboratory results for three different types of oil-containing wastewater. After passing through KC-100 COD adsorbent filtration, the COD removal efficiency is approximately 70% or higher.
