Many food processers use salt, resulting in high strength, high salt content wastewater. The goal of this study was to determine the impact of salt concentration on the treatment of turkey slaughterhouse wastewater using sand/gravel bioreactors. Six unsaturated sand/gravel columns were intermittently dose treating the wastewater in a single pass. Turkey processing wastewater served as the control and 3 g/L and 6 g/L of table salt were added to wastewater for treatment is duplicate laboratory columns. BOD5 and NH3-N removal was measured during the 74-day experiment. The BOD5 removal achieved and maintained over 99% after day 21 at all salt levels. The NH3-N removal achieved over 99% removal after day 32. The conductivity of the effluent matched the influent indicating that the treatment system did not remove salt. It was concluded from this study that sand/gravel bioreactors were able to treat high strength, high salinity (up to 0.6%) turkey slaughterhouse wastewater. The biofilm developed on the sand/gravel surface is the functional part of wastewater treatment. In this study, ATP was measured to investigate the impact of salt on the biomass in the treatment system. Sand/gravel samples were collected from each layer of the columns in the wastewater control and wastewater plus 6 g/L salt. The results showed that salt had an initial inhibition on the biomass in the system. System performance decreased as the biomass declined. After the biomass reached a steady level, the treatment performance was maintained at high level. The study also found that the coarse sand layer was the most active layer treating wastewater.
