Wastewater treatment plants (WWTPs) are designed to remove contaminants from domestic and industrial wastewater before it is released into the environment. [31] However, some WWTPs, particularly older or under-resourced ones are not equipped to effectively remove all CEC, such as advanced pharmaceuticals, personal care product ingredients, and ...
It differs from traditional drug testing, urine or stool testing in that results are population-level rather than individual level. Wastewater-based epidemiology is an interdisciplinary endeavour that draws on input from specialists such as wastewater treatment plant operators, analytical chemists, molecular biologists and epidemiologists.
Polishing is also an example. The main by-product from wastewater treatment plants is a type of sludge that is usually treated in the same or another wastewater treatment plant. [2]: Ch.14 Biogas can be another by-product if the process uses anaerobic treatment. Treated wastewater can be reused as reclaimed water. [3]
Secondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. [ 1 ] : 11 The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option.
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
[42] An industrial wastewater treatment plant may include one or more of the following rather than the conventional treatment sequence of sewage treatment plants: An API oil-water separator, for removing separate phase oil from wastewater. [43]: 180 A clarifier, for removing solids from wastewater. [44]: 41–15

Typically, the floating high speed surface aerators are rated to deliver the amount of air equivalent to 1 to 1.2 kg [[O 2]]/kWh. However, they do not provide as good mixing as is normally achieved in activated sludge systems and therefore aerated basins do not achieve the same performance level as activated sludge units. [6]
