There are certain requirements incumbent upon the wastewater operator when the volume and nature of waste coming into the wastewater treatment plant (WWTP) changes — first and foremost of which is recognition.
That’s the easy part, as the changing levels of your equalization tank(s) should be a clear indicator. For volumetric increases, lab analysis and (hopefully) communication with local dischargers will help determine the nature of the waste. Decreases are decidedly more welcome in that they can result in plant savings, but both increases and decreases require additional action once the process flow rate is altered.
A change in the flow rate creates a chain reaction of related — but often overlooked — system requirements, according to Daniel Theobald, wastewater consultant and owner of Environmental Services. Theobald suggests these three follow-up tasks for optimized operations once your process flow rate changes:
When it comes to efficient operations — where time is money and both are in short supply — awareness and responsiveness can help you save on precious resources. In light of this, Theobald’s message is don’t just “set it and forget it” when it comes to your process flow rate.
What further suggestions do you have for adjusting operations to flow rates? Can you name another often overlooked but important task at the plant?
