How to Use Heavy Metal Capture Agent
Heavy metal capture agents work by utilizing chelating groups that bind with heavy metal ions, forming hydrophobic complexes that precipitate out of solution. In addition, the agent's polymer structure enhances flocculation and net trapping, significantly increasing sedimentation speed and removal efficiency. This method overcomes the limitations of traditional linear chelation processes.
Small-Scale Testing Method
- Take a certain amount of heavy metal wastewater into a container.
- Adjust the pH of the sample to approximately 10 using pH neutralizing powder. Measure the concentration of heavy metal ions and calculate the required dosage of MCP-1 based on the detected level.
- Add the MCP-1 agent and mix thoroughly.
On-Site Application
- Add the MCP-1 directly to wastewater containing heavy metal ions. It is recommended to stir every 10 minutes for optimal mixing.
- If the heavy metal concentration is unknown, perform laboratory tests first to determine the correct dosage.
- For different concentrations of wastewater, the dosage can be automatically controlled using ORP (Oxidation-Reduction Potential) sensors for efficient treatment.
Usage Precautions
- First, adjust the pH of the wastewater using pH complex alkali. After adjusting the pH, test the heavy metal ion content and calculate the required dose accordingly.
- Dilute the product after use. A general dilution ratio of 5% to 15% is recommended. Use tap water or non-metallic ion water for dilution—avoid using groundwater.
- After dilution, it is advisable to add the agent after neutralization to save costs and improve efficiency. You may also add an inorganic or organic flocculant after chelation to enhance the overall treatment effect.
- The agent is a strong alkaline liquid. Avoid direct contact with skin. If contact occurs, rinse thoroughly with water.
This detailed guide ensures safe and effective usage of the heavy metal capture agent in both lab and field settings, helping to achieve optimal results while maintaining safety standards.
