Limits of salinity ,chloride and conductivity for biological treatment

Dear friends,

I have a treatment plant of wastewater for a fish Canning industry with a concentration of chlorure (Chlorine) of 15000 mg/l and a conductivity of 22000 uS/cm.

Is there any impact on the biological treatment for this type of wastewater?

What's the limits of chlorure, salinity and conductivity for the biological treatment?

and if There is any impact, which plant technology should I chose?

Thank you!
