Wastewater treatment, Water reuse, Water quality, Molecular methods, Microbial contaminants
The scientific community can help to advance wastewater reuse in two important ways: First, through the exploration of new treatments and technologies that allow use of safe water supply alternatives, and second, through development and use of new methods that improve insights on water quality. Examples of these two contributions are provided here in the Frontiers Research Topic Microbial Safety in Water Resources.
Wastewater treatment technologies serve as important engineering barriers to remove majority of the contaminants from wastewater, hence achieving safe water reuse or disposal to the natural environment. The conventional wastewater treatment process include clarifiers or sedimentation tanks, activated sludge processes, and disinfection. In recent years, membranes (e.g., microfiltration) are also retrofitted into activated sludge tanks to form aerobic membrane bioreactors, which in turn improve solid-liquid separation and hence achieve high effluent quality.
