  • Biofilm Processes

    The biofilm process is a process which uses a biofilm for the purposes of filtration, bioremediation or barrier formation. A biofilm is a complex and heterogeneous matrix of microorganisms attatched to and growing on a surface. Biofilms are most often found on solid substrates that are exposed ...

  • 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 ...

  • TEP and biofilm fouling on membranes

    Summary Biological fouling on membranes is a major problem in desalination and water purification plants. Oceanographers and limnologists have found that most marine and fresh waters are full of microscopic Transparent Exopolymer Particles, otherwise known as TEP. In this article, aquatic microbiologist Tom Berman and Filtration Specialist Marina Holenberg (Amiad Filtration Systems, Amiad, ...

  • 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 ...

  • Effect of biofilm on colloid attachment in saturated porous media

    Biofilm plays an important role in controlling the transport of colloids in a porous media. Biofilms are formed when micro-organisms come in contact with substrates, and are able to attach and grow with availability of nutrients. The microorganisms get embedded in a matrix of the substrate and extracellular polymeric substances which are responsible for the morphology, physico-chemical ...

  • Organic removal activity in biofilm and suspended biomass fractions of MBBR systems

    The moving bed biofilm reactor (MBBR) wastewater treatment process is usually designed based on the assumption that all activity in the process occurs in the biofilm on the MBBR carriers, although there is always some active biomass in the bulk liquid due to biofilm sloughing and, sometimes, free-growing bacteria. In this study the removal of organic matter is evaluated in laboratory-scale MBBR ...

  • Quantification of kinetic parameters for heterotrophic bacteria via respirometry in a hybrid reactor

    Over the last decade new technologies are emerging even more for wastewater treatment. Among the new technologies, a recent possible solution regards Moving Bed Biofilm Reactors (MBBRs) that represent an effective alternative to conventional processes. More specifically such systems consist in the introduction of plastic elements inside the aerobic reactor as carrier material for the growth of ...

  • Plot testing of mbbr and ifas treatment processes for nitrification and denitrification at the mamaroneck wwtp

    ABSTRACT The Mamaroneck WWTP is one of four WWTPs in Westchester County that the New York State Department of Environmental Conservation (NYSDEC), through its State Pollution Discharge Elimination System (SPDES), imposed Waste Load Allocation (WLA) limits for nitrogen because of its discharge into the ...

  • 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 ...
