  • Use of non-linear mixed-effects modelling and regression analysis to predict the number of somatic coliphages by plaque enumeration after 3 hours of incubation

    The present study aimed to establish the kinetics of the appearance of coliphage plaques using the double agar layer titration technique to evaluate the feasibility of using traditional coliphage plaque forming unit (PFU) enumeration as a rapid quantification method. Repeated measurements of the appearance of plaques of coliphages titrated according to ISO 10705-2 at different times were ...

  • Effect of coagulant basicity on virus removal from water by polyferric chloride

    We investigated the effect of coagulant basicity on bacteriophage removal from river water by polyferric chloride (PFC). PFC at three basicities (basicity 0.9–2.1) was prepared by means of base titration (NaOH was added to ferric chloride (FeCl3) solution) and the virus removal efficiencies of those PFCs were compared with that of FeCl3 (basicity 0). The virus removal efficiencies of the ...

  • Moisture in Oils: The Three-Headed Beast

    Abstract Moisture contamination in in-service lube oils is perhaps one of the most destructive forms of engine corrosion second only to particle contamination.  Water contamination in oil can be categorized into three forms of water; Free, emulsified, and dissolved.  All forms of water have direct consequences to the oil and gears of the engine, but indirect consequences as ...

  • Method for Computing alkalinity based on Total Inorganic Carbon (TIC) and related data case study

    Summary Standard Methods (Ref. 1) has a procedure using nomographs for estimating COt concentrations (Method 4500-CO2 B) based on total alkalinity titrations. The method presented here reverses that process by computing alkalinity based on TIC measurements using infrared technology. These two methods are demonstrated to be compatible, which is not surprising since they use the same ...

  • Why can’t I control the pH of my aquifer? - pH and Acidity are not the same

    Acidity is the amount of base required to neutralize acids present in a water sample. This is important because it determines the amount of buffer required to adjust aquifer pH. Since acids can disassociate to different extents, two solutions with the same pH can have different acidities. The figure to the right shows the pH of solutions containing 0.5 N HCl and 1.0 N acetic acid. The initial pH ...

  • Time is of the essence in plastics

    Introduction Determining the moisture content in plastics is an important step in the extrusion and molding process of many industrial resins.  Excessive moisture content can lead to microscopic steam pockets that can blister or weaken the integrity of the molded product.  Plastic pellets in a saturated or ‘wet’ state can also mislead buyers of bulk plastic since ...
