Simulation of Bar Screens<\/span><\/strong><\/span><\/p>\n

What are the benefits of hydrograv simulations?
\n<\/span><\/strong><\/span><\/p>\n

    \n
  • Ensuring an equally distributed inflow to each bar screen<\/li>\n
  • Prevention of depositions in the up and downstream area<\/li>\n<\/ul>\n

    Example 1: Calibration by measurements<\/span>
    \n<\/strong><\/p>\n

      \n
    • Calibration of the modelling approaches including the degree of debris by measuring the water levels<\/li>\n
    • Comparison at different discharges<\/li>\n<\/ul>\n

      Example 2: Determination and optimization of the distribution of waste water substances
      \n<\/span><\/strong><\/p>\n

        \n
      • Status quo: unequal distribution of substances even though both bar screens receive the same hydraulic loading<\/li>\n
      • The distributary channel\u00a0 is higher loaded with substances<\/li>\n<\/ul>\n

        Recommendation with simulation:<\/p>\n

          \n
        • A separation baffle leads to a different distribution of the currents which improves the distribution of waste water substances<\/li>\n<\/ul>\n
