A model cooling tower/trickling filter was used to study acceptable BOD level in wastewater reuse as cooling system makeup and the effect on the system biofouling. Tap water was used to makeup for evaporation and blowdown while phenol solution was metered as the contaminant, into the circulating water. The phenol was degraded in the tower with less than 2 ppM in circulation at equivalent makeup concentrations below 1200 mg BOD/L. The rate of biofouling, measured by heat transfer coefficient, was correlated with phenol loading rates. Makeup concentrations below 1000 mg BOD/L gave low fouling rates while concentration above 1200 mg BOD/L resulted in intolerable fouling of exchanger tubes.
