  • What stage is Brazil at in wastewater management?
  • Conclusions The aim of this article is to show the path toward sustainability in wastewater management and what stage Brazil is at. It shows that Brazil is still at stage 1 (prevention of or reduction in pollution at the source), although it has already achieved some items related to stage 2 (wastewater collection and treatment).
  • How much of the world's wastewater is treated?
  • It is estimated that 60% of the global population is connected to sewerage systems; however, only a small proportion of collected wastewater is treated. Developed countries treat around 70% of their wastewater, compared to between 28% and 38% in developing countries.
  • How efficient is EC in wastewater treatment?
  • The efficiency of EC depends on the type of wastewater. For example, COD removal by EC in textile wastewater has been found to be from 40 to 70%, 96% for soluble oils, and 80% for paper waste 137. One of the key factors to consider when using EC for the treatment of industrial wastewater is the electrode material.
