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.
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.
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.
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.
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.
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.
We know the importance of pH to biological wastewater treatment, but alkalinity should be considered equally important for its direct correlation to pH.
Wastewater consultant and trainer Dan Theobald (“Wastewater Dan”) dives deeper into the activated sludge process with calculations focused on MLVSS.
“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.
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.
Like Hans and Franz from the classic Saturday Night Live skit, we’re ready to “Pump you up!” with training and exercises to conquer operator certification exams. Your trainer, wastewater consultant Dan Theobald (“Wastewater Dan”), presents his latest round of Math Solutions.
“Wastewater Dan” instructs operators on how to perform calculations for combining concentrations.
“Wastewater Dan” helps wastewater operators understand efficiency and recovery with more easy-to-apply mathematical templates.
Water Online contributor Dan Theobald provides a second round of “Math Solutions” devoted to volume calculations (see the initial installment here). Based on 24-plus years of experience in training and consultation, tutorials from “Wastewater Dan” are designed to help the operator both in the field and while sitting for certification exams.
