Tomato-processing wastewaters generated from food-canning industry are typically considered difficult to biodegrade since they contain seed, skin and high particulate and colloidal fractions. A bench-scale and a pilot-scale anaerobic/aerobic system were evaluated and compared for the treatment of high-strength tomato-processing wastewater. The pilot-scale and bench-scale systems had comparable performance based on the removal efficiencies of SBOD, SCOD and TSS of 96–97%, 99% and 91–98%, respectively. Increase of anaerobic hydraulic retention time (HRT) from 0.25 day to 0.5 day resulted in significantly better settling characteristics of the mixed liquor confirmed by the decrease of diluted sludge volume index (DSVI) from 124–189 mL/g to 24–131 mL/g. Increase of temperature from 25°C to 32°C affected biomass activity and sludge settling characteristics, The biomass activity, represented by specific oxygen uptake rate (SOUR), increased from 0.15–0.23 mg O2/mg VSS-day at 25°C to 0.67–1.24 mg O2/mg VSS-day at 32°C. DSVI of mixed liquor increased from 24–131 mL/g at 25°C to 115–173 mL/g at 32°C.
