  • Four Membrane Cleaning Profiles with Micro-90® Alkaline Cleaning Solution, Micro® Green Clean Biodegradable Cleaner and Micro® A07 Citric Acid Cleaner

    SUMMARY Fouling and cleaning profiles of four types of filter membranes were obtained using MICRO-90®, MICRO® GREEN CLEAN and/or MICRO® A07. Simulated fouling processes were performed by using either a synthetic oil emulsion or a combination of the synthetic oil emulsion and a calcium acetate salt bridge mixture. Excellent recovery of permeate flux was obtained with the lowest to ...

  • Moscow snow reveals new air pollutants

    GC-MS analysis of Moscow snow reveals new pollutants in the city air. Cities, with their traffic, industrial centers and factories, usually suffer from some degree of air pollution. Moscow, which houses all of these as well as power plants and an oil refinery, is no different. Regular monitoring of environmental pollutants is common practice in many cities and priority pollutants are detected and ...

  • Rotary drum vacuum filters for production of wallboard-grade gypsum

    ABSTRACT Conventional wisdom is that production of wallboard-grade FGD gypsum requires the use of horizontal belt vacuum filters for dewatering service, to limit cake moisture to 10% or less. New Brunswick Power initially planned to use HBVFs for gypsum dewatering for the FGD retrofit to its 3 x 350 MW Coleson Cove plant. However, project budget constraints led to cost reduction ...

  • Removal of antibiotic resistant E. coli in two Norwegian wastewater treatment plants and by nano- and ultra-filtration processes

    The effectivity of different treatment stages at two large wastewater treatment plants (WWTPs) located in Oslo, Norway, to remove antibiotic resistant Escherichia coli from municipal wastewater was investigated. The WWTPs were effective in reducing the total cultivable E. coli. The E. coli in WWTP samples were mainly resistant to ampicillin (6–27%) and ...

  • Membrane biofouling mitigation through applying electric potential in the CF016 cell

    Membrane filtration is an effective way to remove pollutants and microorganisms from water and wastewater. However, membrane fouling lowers efficiency over time when considering rejection values and water flux.  Fouling is typically biological or particulate; fouling rate is a function of the membrane pore size relative to the size of the foulants and also the interactions between the ...
