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 has been used to estimate illicit drug use in communities or populations, but can be used to measure the consumption of alcohol, caffeine, various pharmaceuticals and other compounds. [2] Wastewater-based epidemiology has also been adapted to measure the load of pathogens such as SARS-CoV-2 in a community. [3]
A methylene blue active substances assay, or MBAS assay, is a colorimetric analysis test method that uses methylene blue to detect the presence of anionic surfactants (such as a detergent or foaming agent) in a sample of water. An anionic surfactant detected by the color reaction is called a methylene blue active substance (MBAS). [1]
Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry.
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 .
EPANET uses a binary file format, but also includes the capability for importing and exporting data in dxf, metafile, and ASCII file formats. EPANET's ASCII file format is called an input file within EPANET, and uses a file extension ".inp". [4] The input file can include data describing network topology, water consumption, and control rules ...
AOAC International, informally AOAC, was founded September 8, 1884, as the Association of Official Agricultural Chemists, by the United States Department of Agriculture (USDA), [1] to establish uniform chemical analysis methods for analyzing fertilizers.
