- •
A SB-MBR pilot plant treating wastewater subject to salinity increase was investigated.
- •
Salinity increase influenced the biological contribution of COD removal efficiency.
- •
Salinity increase did not exert a significant stress on heterotrophic bacteria.
- •
Significant reduction of the respiration rates of autotrophic species due to salt.
- •
The irreversible cake deposition was the predominant membrane fouling mechanism.
