May I ask about the treatment of industrial wastewater!
Thread Content
I am currently facing the challenge of dealing with a type of wastewater that contains 0.5% benzoic acid; I intend to use membrane separation techniques to recycle both benzoic acid and water. What is not certain at the moment is: which membrane to use, nanofiltration or reverse osmosis? Since benzoic acid will precipitate in large quantities when its concentration is too high, and as it is an organic substance, could it cause severe blockage of the membrane pores and lead to a rapid decrease in the membrane’s flux? I hope to get everyone's help! ! :) Thank you! :'(
To the best of my knowledge, there is no mature technology yet for treating wastewater containing benzoic acid using membrane separation or reverse osmosis, but the method of complexation extraction has been reported.
Benzoic acid is of course extracted by complexation
Could you provide more details about the second floor? I don’t have any materials on this topic!
This is the right way to do it; if you use a membrane, I guarantee you’ll lose money.
You can take a look at this book on the forum: http://bbs.hcbbs.com/thread-48111-1-15.html
Support! For joint learning and progress discussion, it is recommended to use microelectrolysis for experiments.
0.5% benzoic acid can be used for the adsorption by resins to recover organic matter. If higher standards are required for the reclaimed water, further treatment can be carried out; if the standards are not strict, the water can be used directly, which reduces operating costs.
