Discussion on Salinity in Biological Wastewater Treatment
Thread Content
What is the salt content in the biological unit at your factory? What impacts has it had on biological units? Could you share some experience in this area?
Under normal operation, it is generally kept below 3000.
You can post a separate thread dedicated to explaining electrodialysis, but make sure it doesn’t contain any content that might be considered advertising.
High levels of chloride ions, or high levels of nitrate and nitrite ions, have a significant impact on the determination of COD. High chloride ion levels interfere with the measurement of COD, causing the COD values to increase, while nitrate and nitrite ions, due to their reducing properties, also cause an increase in COD values.
