Wastewater Update!

As we have traveled around Minnesota, North Dakota, South Dakota, and Wisconsin over the past few months visiting water resource recovery facilities and engineers, we have received questions specifically around phosphorus removal when it comes to process monitoring and control. Learn how we (and our partner YSI) are addressing phosphorus removal with our monitoring and control instrumentation.

Q: My facility is preparing for new phosphorus discharge limits that are being added to our permit. I am able to remove some phosphorus biologically but sometimes I need to add chemical to reach the new limit. How do I know when I need to dose chemical so I can meet the new discharge limit without over dosing? I don’t want to dose chemical and add expense to the process when the bio-P removal is enough.A: As mentioned in the question, there are two strategies for removing Phosphorus: biological and chemical. YSI offers an orthophosphate analyzer, the P700, that will allow you to continuously monitor the phosphorus levels in your process. This helps determine if you are meeting your permit and allows you to control chemical addition when necessary, based on the measurement.
