  • 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 ...

  • Establishing Biofilm Control Strategies for Drinking Water Systems

  • Biofilm Control for Industrial Waters

    Industrial operations can face a number of serious problems due to bacterial Biofilms growing in process water systems and cooling tower waters. Biofilm-induced corrosion, mechanical blockages and impedance of heat transfer processes result in huge monetary losses each year. In engineered systems, additional risks of biofilm-mediated contamination include negative public health consequences and ...

  • 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  ...

  • Waterborne microorganisms and biofilms related to hospital infections: strategies for prevention and control in healthcare facilities

    Water is the main stimulus for the development of microorganisms, and its flow has an important role in the spreading of contaminants. In hospitals, the water distribution system requires special attention since it can be a source of pathogens, including those in the form of biofilms often correlated with resistance of microorganisms to various treatments. In this paper, information relevant ...

  • A framework for good biofilm reactor modeling practice (GBRMP)

    A researcher or practitioner can employ a biofilm model to gain insight into what controls the performance of a biofilm process and for optimizing its performance. While a wide range of biofilm-modeling platforms is available, a good strategy is to choose the simplest model that includes sufficient components and processes to address the modeling goal. In most cases, a one-dimensional biofilm ...

  • Integrated approach for biofouling control

    Despite extensive research efforts, past and present strategies to control biofouling problems in spiral-wound nanofiltration and reverse osmosis membranes have not been successful under all circumstances. Gaining insight in the biofouling process is a first necessity. Based on recent insights, an overview is given of 12 potential complementary approaches to solve biofouling. Combinations of ...

  • Aggregation and biofilm formation of bacteria isolated from domestic drinking water

    The objective of this study was to investigate the autoaggregation, coaggregation and biofilm formation of four bacteria namely Sphingobium, Xenophilus, Methylobacterium and Rhodococcus isolated from drinking water. Auto and coaggregation studies were performed by both qualitative (DAPI staining) and semi-quantitative (visual coaggregation) ...

  • Influence of the shear stress and salinity on Anammox biofilms formation: Modelling results

    Anammox biomass has a relatively long duplication time and low yield. This is an advantage because the production of surplus sludge is reduced; however it also implies that the process must be operated in reactors with very good sludge retention. Some of the systems used to improve biomass retention are based on biofilm reactors; therefore, the objective of this work was to study the ability of ...

  • Preventative control of legionella through real-time bioburden testing

    Abstract: Of the 485,000 annual cases of pneumonia-like sickness in the USA, approximately 15% are attributed to Legionnaire’s Disease. This typically results in  health care costs of over $600 million (1, 2, 3). For the most part, these incidents can be prevented through effective monitoring and treatment. Since Legionella thrive within microbial biofilms and ...

  • Controlling scale in water systems helps prevent legionella

    The Legionella bacterium, Legionella Pneumophila (LP), the fundamental agent of Legionnaire’s Disease, is a water-based organism, which causes infection when inhaled in an aerosol form. Legionnaires' Disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness ...

  • Composition and distribution of bacteria in an operating rainwater harvesting tank

    In this study, we investigated the phylogenetic distribution of the bacteria present in an operating rainwater tank by denaturing gradient gel electrophoresis (DGGE), and compared the bacterial composition in rainwater and biofilm from the inlet and outlet of the tank. Seventeen species were identified, the DGGE profiles of which showed a clear difference between the planktonic bacterial ...

  • SCORe-CT: a new method for testing effectiveness of sulfide-control chemicals used in sewer systems

    A new method for testing the effectiveness of chemical products for sulfide control in sewers is reported. The method, called SCORe-CT (Sewer Corrosion and Odour Research – Chemical Testing), consists of two specially designed laboratory-scale systems that mimic sulfide production in real rising main sewers, and a multi-phase and multi-facet testing protocol. The monitoring tools/methods include ...

  • BM Respirometry applied to a novel control strategy of nitrification in a wastewater biological treatment

    In wastewater treatment plants, the biological nitrogen removal (BNR) has acquired critical importance, which makes that in the majority of the cases the overall process control largely depends on the control of this treatment. The normal aerobic process of nitrification is performed by specific aerobic living microorganisms and a lack of information on their bioactivity may be cause of confusion ...
