  • Can physicochemical methods be used to treat process wastewater?
  • This phenomenon opens the application area of physicochemical methods for the treatment of process wastewater and can contribute not only to the aims of the circular economy but also to the zero liquid discharge. Besides literature studies, authors’ own results and innovations have been also presented.
  • How was wastewater treated in China in the 1970s?
  • In the early 1970s, wastewater treatment in China was mostly accomplished through the renovation of natural terrains such as abandoned rivers, depressions, and marshes, as well as establishing stabilization ponds to perform simple primary wastewater treatment .
  • How is China promoting industrial wastewater treatment?
  • In the recent decade, China's government and enterprises have worked together to take a series of actions for promoting the development of industrial wastewater treatment, including establishing policies and targets, innovating production technologies, eliminating backward production capacity, and reducing unit production water consumption.
  • What are physicochemical and tertiary wastewater methods?
  • Hereinafter, physicochemical methods for the treatment of chemical PWWs are presented and evaluated in light of applicability aspects. Further physicochemical or tertiary wastewater methods are the following: Crystallisation, precipitation, and electrolysis.
