Math Solutions Explained: Calculate Food-to-Microorganism (F-M) Ratio
3/15/2022
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.

RTC-ST Improves Dairy Wastewater Operations & Costs
2/3/2022
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.

SWAN Corner: Wastewater Components Guide Sewer Investigations
12/14/2021
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.

Detecting COVID-19 Early Via Wastewater Surveillance
10/25/2021
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.
