  • 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  ...

  • 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 ...

  • Algae and Biofilm control project for a drinking water treatment plant in Cyprus

    For the Ministry of Agriculture in Cyprus, LG Sound b.v installed 33 LG Sonic, ultrasonic devices in the Limassol water treatment plant, to prevent bad odour and taste to the water caused by geosmins in the water. The earthy taste problem persisted during summer of 2010 and various physical, chemical and biological tests were done in order to check the process efficiency, which showed ...

  • Removing biofilm from membranes – a practical approach

    Abstract Within the lifetime of most reverse osmosis (RO) systems some fouling will adversely affect membrane performance.One of the major foulants identified on lead membranes during a decade of membrane autopsy at the Genesys Membrane laboratory is biological fouling (biofouling). All raw water sources contain microorganisms such as algae, bacteria and fungi. They also contain ...

  • Biofilm control in water by advanced oxidation process (AOP) pre-treatment: effect of natural organic matter (NOM)

    The main goal of this study was to examine the influence of natural organic matter (NOM) on the efficiency of H2O2/UV advanced oxidation process (AOP) as a preventive treatment for biofilm control. Pseudomonas aeruginosa PAO1 biofilm-forming bacteria were suspended in water and exposed to various AOP conditions with different NOM concentrations, and compared to natural waters. H2O2/UV prevented ...

  • Diffussive tortuosity factor of colloidal cake and biofilm

    Membrane fouling of fine colloids and biocolloids is ubiquitous in pressure-driven membrane processes, such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO). In MF/UF, colloidal fouling is initiated by rapid formation of the concentration polarization (CP) layer, and is significantly enhanced by gradual development of the cake layer of colloidal maximum ...

  • 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 ...

  • Microbial control reduces sulfide

    The article is about sewage odour control using a totally NEW technology known as Microbial Control. Microbial control treats the cause of sewage odour, corrosion and methane gas production in sewers by removing the biofilm / sediment (slimes) complexes where sewage odour and methane gas are produced. Without sewage odour you cannot have sewage infrastructure corrosion from sulfuric acid. As ...

  • The use of microsensors to study the role of the loading rate and surface velocity on the growth and the composition of nitrifying biofilms

    The good composition and activity of biofilms are very important for successful operation and control of fixed-film biological reactors employed in liquid effluents treatment. During the last decade, microsensors have been applied to study microbial ecology. These sensors could provide information regarding the microbial activity concerning nitrification and denitrification that occur inside ...

  • Hydroxyl-Radical Odor Control

    In-Pipe now offers the IPTC(OH-), a hydroxyl radical based odor control option for Lift Stations and WWTP headworks that requires no chemicals, needs only a small footprint and uses minimal electrical power. The IPTC(OH-) chemical free scrubber system connects to the existing lift station vent to oxidize hydrogen sulfide outside of the lift station environment in order to scrub odors before ...

  • Biofouling Control in Small Cooling Towers

    Why is biofouling control overlooked in small cooling towers? Biofouling control in small to medium cooling towers is overlooked. AMSA, Inc. has developed a simple technology that is easier to dose than more common liquid chemical ...

  • Comparative study on membrane fouling between membrane-coupled moving bed biofilm reactor and conventional membrane bioreactor for municipal wastewater treatment

    This study compared the performance between membrane-coupled moving bed biofilm reactor (M-MBBR) and a conventional membrane bioreactor (MBR) in parallel. Extensive tests were conducted in three pilot-scale experimental units over 6 months. Emphasis was placed on the factors that would affect the performance of membrane filtration. The results showed that the concentrations of soluble microbial ...
