Abstract:  With the decrease of water resources, the use of advanced treated refinery wastewater in recirculation cooling water system is an effective method to save water and to reduce the pollution of petroleum and petrochemical industry. However, the control of biofouling is the bottleneck in the application of this technology. So the effects of flow velocity and temperature on the components and characteristics of biofouling were investigated in a dynamic model unit of recirculation cooling water system. The results showed that the content of extracellular polymeric substance and the mechanical intensity of biofouling both reached its biggest values, but biofouling wet mass was low at the flow velocity of 1.0 m/s or at the temperature of 30¡ãC. It is concluded that the operating conditions of 1.0 m/s and 30¡ãC were the optimum conditions to control the biofouling in the recirculation cooling water system.
