MBBR Denitrification for Salty Water

I have an interesting case of MBBR treatment for denitrification process. I have experience with this process, but in this case the water is salty: 15 to 35 ppt. I don't know how much the salinity will affect efficiency, need for carbon, removal rates, etc. Do you have experience with salty water denitrification? Can you give me some info or suggest books and articles on the topic?
