Flush and forget? Not if you have a toilet that flushes to one of over 3,000 sites around the world where researchers are using wastewater to track SARS-CoV-2, the virus that causes COVID-19. But what do members of the public actually know about wastewater surveillance? And what do they think about researchers tracking what they send down the drain at their home?

In Part Two of Navigating Through Uncharted Waters, we caught up with Peter Ng, a Wastewater Technician who continues to help get wastewater samples for Covid research. At the beginning of the pandemic, Ng was tapped to be a Disaster Service Worker for the City and County of San Francisco helping to deliver food to the vulnerable population as well as be a translator to senior citizens. As Ng explains, this was something he was always meant to do.

The food-to-microorganism (F-M) ratio is a process control numeric value advantageous to determine the proper number of microorganisms for the biological treatment process. The solution of calculating F-M ratio uses the influent volume of wastewater into an activated sludge system (flow MGD), incoming carbonaceous biochemical oxygen demand (CBOD) (mg/L) concentration into the aeration tank, mixed liquor volatile suspended solids (MLVSS) concentration (mg/L), and quantity (in gallons) of the respective aeration system.

Problem: A wastewater treatment plant in a large dairy facility was looking for ways to reduce chemical coagulant costs and labor to monitor and operate the dissolved air flotation (DAF) unit. Solution: The Hach® Real-Time Control for Sludge Thickening (RTC-ST) solution offers real-time coagulant analysis and optimizes dosage. This allows the facility to monitor and remove solids without over-dosing coagulant in the DAF.
