However, the sociodemographic or socioeconomic correlates of chemical consumption and exposure are unclear.

This was based on our finding which revealed a positive correlation between the water quality parameters DO, BOD and TC and population.

low operating ratios (i.e., utilization degree of the designed treatment capacity) of the plants (76% in counties and 85% in cities) especially for those in north China, although the situation is plant specific because a considerable fraction of plants (19%) are still running under overload condition.

The goal is to go beyond minimizing pollution and find ways to recover wastewater.

Wastewaters have daily emerged from various activities like households, agricultural, and industrial, with huge hydraulic loads and diverse compositions

Wastewater treatment plants (WWTPs) are a focal point for the removal of microplastic (MP) particles before they are discharged into aquatic environments.

The flow values at each measuring point depend on the number of inhabitants in the catchment drained by the sewer system

and therefore those of wastewater. In an urban context, the highest values of COD, TSS, BOD, etc. are usually measured during diurnal hours, with a peak in the morning (more pronounced) and several peaks in the early evening (more distributed)

Toilets produce the most important loads of nitrogen, phosphorus and suspended solids (Gray and Becker, 2002). They represent 60 to 90% of the total flow at the end of the night or early morning and 20–40% during the day.

The PE number of a system influences treatment stability with systems with smaller numbers being less stable

there is a decrease in average BOD discharged as plants increase in size
