Wastewater sampling flowchart. Wastewater surveillance is the process of monitoring wastewater for contaminants. Amongst other uses, it can be used for biosurveillance, to detect the presence of pathogens in local populations, [ 1] and to detect the presence of psychoactive drugs. [ 2]
Wastewater quality indicators are laboratory test methodologies to assess suitability of wastewater for disposal, treatment or reuse. The main parameters in sewage that are measured to assess the sewage strength or quality as well as treatment options include: solids, indicators of organic matter, nitrogen, phosphorus, indicators of fecal ...
Wastewater-based epidemiology (or wastewater-based surveillance or sewage chemical-information mining) analyzes wastewater to determine the consumption of, or exposure to, chemicals or pathogens in a population. This is achieved by measuring chemical or biomarkers in wastewater generated by the people contributing to a sewage treatment plant ...
Over the past two years, as the idea of sampling sewer systems for the virus that causes Covid-19 and other pathogens has caught on across the country, the Texas Epidemic Public Health Institute ...
Lake Kickapoo is a reservoir located on the North Fork Little Wichita River in the Red River Basin of Archer County, Texas. It is neighbored by Archer City, Texas (population of 1,834) and Wichita Falls, Texas (population of 104,553) which reside within the Central Great Plains ecoregion. [1]
A rotating biological contactor is a type of secondary (biological) treatment process. It consists of a series of closely spaced, parallel discs mounted on a rotating shaft which is supported just above the surface of the wastewater. Microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes ...
The US is in the midst of a significant Covid-19 wave, with viral activity levels in wastewater the highest they’ve been for a summer surge since July 2022, according to the US Centers for ...
Trickling filter. A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime ( biofilm) to grow, covering the bed of media.
