You are making your plant rounds and looking, listening, smelling, maybe touching, hopefully not tasting, and writing down lots of numbers. These could be flows, hour meters, DO’s, pH, and many more. Do you ever ask yourself “what do these numbers mean.”
I was on-site one time and noticed a large difference in daily flow measurement. I asked the operator if he had noticed any difference. He informed me, that “all he did was write down the numbers”. A scary thought that an operator, first line of quality control, was not paying attention to their job. So, I ask again, “do you know what those numbers mean?” If you don’t, then ask.
What do your operators know about the monitoring numbers they record?
