Concentrate treatment in reverse osmosis
Thread Content
I’m reaching out to all the forum members for help. I’m facing a problem with a project I’m working on: the COD level of the concentrated water produced after reverse osmosis is significantly above the allowed limits. Is there any way to deal with this issue? I’d be very grateful

If the amount of liquid in the concentrate is not too large, we can use our vacuum evaporation drying technology, which is particularly suitable for high-salt and high-COD substances
The COD of the raw water entering the reverse osmosis system is around 170, and the volume of water is approximately three to four thousand cubic meters
Can high-salinity water from RO be treated biologically? What process is used?
I have a question: if the COD value of concentrated water is high, will it cause clogging in the EDI membranes? What is the required COD level for EDI feed water? Thank you!
