    1/10/2018

    With almost 30,000 total views in 2017, the “Math Solutions” series of tutorial videos from wastewater consultant and trainer Dan Theobald ("Wastewater Dan") has offered plenty of guidance to treatment plant operators. Here are the lessons that drew the most attention.

  2. Math Solutions: Flow Velocity Calculations
    5/2/2017

    Flow velocity is defined in fluid dynamics as the specific distance (feet, yards, or miles) fluids such as water and wastewater travel in an exact period of time including seconds, minutes, or hours. In managing your water/wastewater, applying this tool can be very useful.

  3. Math Solutions: Helpful Math Hints And Calculations
    3/28/2017

    Mathematical calculations can be a challenge for even the most skilled water and wastewater operator. The formulas for chemical dosing, conversion, filtration, pounds, velocity, volume, and other everyday problems vary, of course, but there are a scant number of basic ground rules that can help make sure your math solution is legitimate regardless of the calculation you’re performing.

  4. Math Solutions: Certification Examination Prep Calculations
    2/15/2017

    While it is natural to be worried about the unknown, being apprehensive can lead to less achievement. Conversely, knowing what to expect more likely leads to relaxation and accomplishment — and can ultimately help you pass the exam.

  5. Math Solutions: Energy Dollar Savings Calculations
    1/6/2017

    Energy efficiency, as defined in wastewater treatment, is using less energy to provide the same service. It can be expressed as energy dollar savings by replacing older, inefficient motors.

  6. Math Solutions: Hydraulic Loading Calculations
    11/30/2016

    This tool for operators, represented through video tutorials, offers mathematical templates to master the hydraulic loading gallons per day per square foot by evaluating the incoming flow and surface area.

  7. Math Solutions: Alkalinity Calculations
    11/2/2016

    We know the importance of pH to biological wastewater treatment, but alkalinity should be considered equally important for its direct correlation to pH.

  8. Math Solutions: Mixed Liquor Volatile Suspended Solids (MLVSS) Calculations
    10/4/2016

    Wastewater consultant and trainer Dan Theobald (“Wastewater Dan”) dives deeper into the activated sludge process with calculations focused on MLVSS.

  9. Math Solutions: Sludge Age Process Control Calculations
    9/7/2016

    “Wastewater Dan” helps operators solve for sludge age and optimize the activated sludge process using sample problems and easy-to-use math templates to inform real-world calculations.

  10. Math Solutions: Activated Sludge Process Control Calculations
    8/5/2016

    Some wastewater calculations rely on multiple math steps to arrive at the conclusion, complicating an already challenging aspect of the operator’s role. Wastewater consultant and trainer Dan Theobald helps operators overcome the intimidation of solving activated sludge process control by offering a step-by-step tutorial.
