  • pH neutralization system daily

    As discussed in the August Newsletter, a Fully Automated Industrial Wastewater Pretreatment System will shutdown and temporarily holds wastewater for proper treatment if an out-of-spec condition, an excursion, is detected. These systems require checks only twice a week and an operator on-call. All other systems require a daily operator inspection. Fortunately, a well designed system requires ...

  • Measurment of pH in Low Conductivity Water

    Measuring pH of pure water. The measurement of pure water pH can be one of the quickest indicators of process contamination in the production or distribution of pure water. The presence of gaseous contaminants such as air or carbon dioxide will shift the pH of the pure water, indicating air or gas intrusion into the process line. The exhaustion of resin beds used to prepare ...

  • ASTM D1287 - 11 standard test method for ph of engine coolants and antirusts

    pH is a measure of the hydrogen ion concentration and indicates whether an engine coolant, antirust, or a solution of these compounds is acidic, alkaline, or neutral. The pH range includes values from 0 to 14. Values from 0 to 7 represent the acidic half of the scale. Values from 7 to 14 represent the alkaline or basic half of the scale. The pH value 7 is considered neutral, ...

  • Peristaltic pump tackles troublesome pH levels at food manufacturer

    Leading convenience food manufacturer, Greencore Group Plc, has achieved significant savings in downtime and repair costs on the water treatment plant at its Greencore Grocery site in Selby, North Yorkshire, thanks to the installation of a Bredel SPX50 high pressure peristaltic hose pump from Watson-Marlow Pumps Group. Greencore Grocery is one of the UK's leading manufacturers of ...

  • Developing Bioaugmentation Cultures for Chloroethene Remediation in Low pH Aquifers

    One of the major limitations for bioremediation of chlorinated ethenes in aquifers with a pH of approximately 6 and below is the perceived need to adjust the pH to the circumneutral range. This is based on numerous studies with Dehalococcoides and mixed cultures containing Dehalococcoides that indicate a steep reduction or cessation in cDCE and VC reduction to ethene at pH levels below 6. ...

  • Soil acidity threatens Australian farming production

    Soil acidity and subsurface acidity in particular is a widespread and significant constraint threatening production and flexibility in the farming system. Maintaining optimal pH is necessary if farm productivity is to be maintained. It therefore falls on growers to assess their circumstances and determine long-term goals for soil management. If there’s no quick fix solution, a longer term view is ...

  • Growth of algae affected by ocean acidification and nutrient pollution

    Ocean acidification and eutrophication may affect the growth of microscopic algae — phytoplankton — with knock-on impacts for marine food chains and fisheries, warns a new study. By growing phytoplankton under different scenarios the researchers found that phytoplankton species are affected differently according to the acidity and nutrient content of the water. Ocean acidification is ...

  • Stop guessing shades of red, orange, purple, … new optical sensor for automated photometric titrations

    Many titrations are still often performed manually because regulations require a titration to continue until the color changes; in other words, the endpoint must not be indicated by a pH electrode or a metal electrode. Guessing shades of red, orange, purple, etc., however has an end, as such titrations can now be automated with a new optical sensor, the Metrohm  ...

  • Rising temperatures and acidification in the oceans spell danger for shark populations

    Increasing temperatures and rising ocean acidification could reduce the health and survival of young sharks, new research has shown. Bamboo shark embryos incubated under ocean temperatures and acidity predicted for 2100 showed survival rates of 80% compared to 100% survival under present-day conditions. Once hatched, survival measured at 30 days was only 44% for those under predicted climate ...
