How can these chloride ions be removed from wastewater?
Thread Content
In the polymerization process, chloride ions are introduced, and the wastewater after the reaction contains 1% chloride ions. How can these chloride ions be removed from the wastewater?
Sit in the front row of the benches to watch and see how the experts answer, and learn from it too*
I’ve never heard of a method for removing chloride ions from wastewater. Sodium chloride is a common component in the waste salts that result from neutralization and evaporation. There are ion exchange resins used to remove or concentrate specific cations; I wonder if there are such resins for anions as well
If the composition of water and its acidity or alkalinity can be changed, strong-alkali anion resins can be used for treatment; chloride ions are adsorbed by the anion resins, releasing hydroxide ions and increasing the alkalinity of the water. Additionally, water can be treated by electrodialysis. It’s wishful thinking to think that one can remove chloride ions from water without having any noticeable effect on the water quality.
Do wastewater discharge standards set any requirements for chloride ions?
Thank you all for your replies! :handshake
Soluble solids – sodium chloride, isn’t that included?
Can a 1% concentration be used for electrolytic dechlorination?
