Removal of COD
Thread Content
For the closed-loop circulation of mineral processing return water, with a COD level of 2000, to reduce it below 50, what processes and chemicals should be used?
If the closed-loop cycle uses little reagent, the open-loop cycle uses more. We have specialized chemical agents for removing COD. You can add my contact information. QQ: 898617481, WeChat: 15128696537.
Are you removing COD or masking COD?
Please provide details about the quality of your water; just having COD data is far from enough, and it’s not possible to give you any advice
The specific water quality test results are not available yet; they will be sent once they are ready. It mainly involves the treatment and reuse of wastewater from gold mine processing; substances such as xanthate and Oil No. 2 turn into COD in this wastewater.
Since COD is mainly generated by oil, it needs to be removed first through oil separation and air flotation; a small-scale test can be conducted in the laboratory to observe the results
We still need to wait for your test results to come back.
