Global warming is an ever-present problem resulting in increasing sea level rise and surge flooding. Many coastal wastewater treatment facilities have already experienced problems relating to higher concentrations of seawater in their wastewater influent. The effects of salinity on the sedimentation and aeration activated sludge processes were analyzed to determine what mitigation techniques could be employed. Experimental results suggested that at concentrations of salinity between 2.63 and 5.24 percent by weight, the traditional sedimentation and aeration processes could no longer operate effectively. A monitoring system was designed to trigger a process control response during high salinity events, which included isolated activated sludge reseeding and reverse sedimentation tanks.
