  • Modeling surface growth of escherichia coli on agar plates

    Surface growth of Escherichia coli cells on a membrane filter placed on a nutrient agar plate under various conditions was studied with a mathematical model. The surface growth of bacterial cells showed a sigmoidal curve with time on a semilogarithmic plot. To describe it, a new logistic model that we presented earlier (H. Fujikawa et al., Food Microbiol. 21:501-509, 2004) was modified. Growth ...

  • Inclined Plate Settlers to Treat Stormwater Solids

    ABSTRACTIt has been well-documented that, in stormwater runoff, many of the problem pollutants are associated with the particulate fraction. Past characterization of urban runoff and source contributions has shown the following: (a) soil disturbance increased the TSS and turbidity in the runoff; and (b) correlations were observed between TSS and particulate runoff concentrations of chromium, ...

  • MAS Introduces Filter Innovation

    Our partner MAS has recently attracted attention for a range of technical innovations in extrusion and plastic recycling technology, including the co-rotational conical twin screw extruder and a waterless cleaning system for film flakes. This ...

  • Wastewater from metal finishing industry set for more regulation from the Environmental Protection Agency

    The U.S. Environmental Protection Agency (EPA) recently released its preliminary 2014 Effluent (liquid waste or sewage discharged into a river or sea) Guidelines Program, which outlined more regulations for wastewater from those within the metal finishing industry. A filter press has been a long-trusted solution for treating metal waste, even for those applications that are difficult to dewater. ...

  • Metal finishing - Columbia manufacturing company - case study

    Application Columbia Manufacturing Company of Westfield, Massachusetts began producing bicycles in 1877. The company, while still producing bicycles, transitioned its core product line to institutional furniture with chrome plated bases made from tubular steel. Large amounts of potable water were required for the old plating system. The company was using 180,000 gallons of potable water a ...


  • How do oil mist collectors work? Comparing the different technologies, part II

    In our previous article about oil mist collector technology, we discussed the pros and cons of centrifugal mist collectors and filter-based mist collectors. Today, we look at the other two most common methods of getting oil mist out of the air. Electrostatic Precipitator Mist Collectors An electrostatic precipitator uses ...

  • Circuit Board Manufacturer

    A circuit board manufacturer was having difficulty with copper and zinc in their wastewater stream. The metals come from etching and plating processes at the facility. Integrated Engineers treated the water with IE-061 (a metal precipitant), and Floccin-1105. The photo on the left shows untreated and treated water samples. Note the clarity of the water in the treated sample. The photo on the ...

  • Does the antibacterial activity of silver nanoparticles depend on the shape of the nanoparticle? A study of the gram-negative bacterium escherichia coli

    In this work we investigated the antibacterial properties of differently shaped silver nanoparticles against the gram-negative bacterium Escherichia coli, both in liquid systems and on agar plates. Energy-filtering transmission electron microscopy images revealed considerable changes in the cell membranes upon treatment, resulting in cell death. Truncated triangular silver nanoplates with a {111} ...

  • Corrugated Sheet Plant

    The previous wastewater treatment was composed of the following chemicals: an acidic coagulant, caustic for pH adjustment, and an anionic polymer made down to 1% solution. The facility used 3-4 gallons of coagulant, 2-3 gallons of caustic, and 2-3 gallons of anionic flocculant (at a 1% solution) at a cost of $50/batch. The operator stated that they had low solids, they tended to overdose which ...
