• What follows is a breakdown of some of the key applications of real-time data access in the wastewater sector.

  • A community’s sewage holds clues about its COVID-19 burden. Over the course of the pandemic, wastewater surveillance has become an increasingly popular way to try to understand local infection trends.

  • 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.

  • Wastewater is suddenly an important source for data and insight for solving problems beyond the scope of traditional water management.

  • Wastewater can be both a potentially harmful pollutant and a valuable resource and a vital raw material. It could be the potential key to sustainable water consumption. 

  • Extraneous water in the wastewater network is likely to increase as the climate change progresses. Wastewater components can offer key information for water utilities for prioritizing network inspections and renovations, such as CCTV and manhole cover inspections. At the same time, calculating wastewater components out of pumping stations data is a valuable example of how water utilities can extract concrete insights from large data sets.

  • Wastewater analytics are already being used around the world to monitor contamination, optimize treatment processes, and catch environmental scofflaws. So why has the U.S. been so slow to adopt these technologies?

  • Wastewater-based epidemiology (WBE) is the analysis of wastewater to identify the presence of biologicals or chemicals for the purpose of monitoring public health. It can provide a snapshot of entire communities from one sample. Detecting viral diseases by way of wastewater monitoring is nothing new, it’s been known for decades that viral particles can be detected in human feces. WBE has previously been used to detect the presence of pharmaceutical or industrial waste, drugs, viruses, and potential emergence of antibiotic-resistant bacteria. In Israel, a wastewater surveillance program for monitoring polio outbreaks has been successfully running since 1989.
