  • Does your cooling tower have a biofouling problem?

    What’s growing in your tower? It’s important to be able to identify microbial biofouling in the industrial cooling systems that you treat. We know that biofouling is a bad thing … reducing the heat transfer performance of a cooling system, as well as causing microbially induced corrosion, harboring pathogens, and accumulating scale deposits. All these problems can ...

  • Effects of pipe materials on biofouling under controlled hydrodynamic conditions

    Experiments were carried out to investigate pipe material impacts on biofouling, at high effluent concentration levels and under controlled hydrodynamic conditions. Two velocities (0.4 and 0.8 m s−1) were used to monitor biofilm growth on polyethylene (PE) and polyvinylchloride (PVC) pipe walls, respectively. These conditions were established based on wastewater irrigation practices. A ...

  • Monitoring of CaSO4 deposition behaviors on biofilm during nanofiltration via ultrasonic time-domain reflectometry (UTDR)

    The ultrasonic time-domain reflectometry (UTDR) as a non-destructive real-time method was employed to monitor the CaSO4 deposition behaviors on biofilm during nanofiltration (NF). Two parallel experiments were performed to compare the different behaviors of CaSO4 deposition with and without biofilm on the membrane. Results showed that the flux decline during combined fouling was slower than that ...

  • Learning to Live With Biofilm: The Challenge of an Effective Biofilm Control Program

    The organism always wins. This is the challenge of biofilm control. Microbial biofouling and its root cause, biofilm, cannot be totally prevented, at least for a practical length of time in industrial settings. We have many approaches to keep it at bay but it will always be with us. In industrial water treatment, our goal is to keep biofouling  ...

  • Biofilm control strategies in industrial processing waters

    Bacterial biofilms cause a number of serious problems for industrial fluid processing operations. Mechanical blockages, impedance of heat transfer processes and microbially induced corrosion result in billions of dollars of losses each year. In engineered systems, such as cooling water systems, food processing, and other industrial applications possible risk to public health and product spoilage ...
