Based on the levels of SARS-CoV-2 in ,wastewater,, methods can be adapted to higher or lower detection limits as needed. For example, if levels of SARS-CoV-2 RNA are sufficiently high in ,wastewater,, small volumes of ,wastewater, (e.g., 1 ml) may be tested without additional ,concentration, processes.

Disinfection of wastewater by hydrogen peroxide or ...

Hydrogen peroxide and peracetic ,acid, in ,wastewater, over time could be modeled as a second-order decay, with the decay "constant" being a function of the initial ,concentration, of peroxycompounds. This function was the same for both hydrogen peroxide and peracetic ,acid,, possibly indicating similar decomposition pathways in ,wastewater, matrices.

Resource utilization of pickling wastewater (waste acid)
Resource utilization of pickling wastewater (waste acid)

A large number of pickling wastewater (waste acid) will be produced in iron and steel processing enterprises. The concentration of heavy metal ions in this kind of wastewater is high. As long as the concentration of heavy metal ions can be reduced, the regenerated acid can be returned to the pickling section for recycling.

Wastewater Surveillance Data Reporting & Analytics | CDC

Wastewater, trend classification is the statistical analysis of changes in the normalized ,concentration, of SARS-CoV-2 in ,wastewater, (i.e. not by qualitative visual assessment). Trends in these ,wastewater, data can be used to assess COVID-19 trends (reported and unreported) within the community contributing to the sewer system.
