  • What is anaerobic sewage treatment?
  • Anaerobic sewage treatment, in various cases followed by units of aerobic post-treatment systems, was regarded an alternative to the traditional wastewater treatment systems used historically, such as the mechanized activated sludge and the land-based pond systems.
  • Can anaerobic technology be used to treat domestic sewage in Brazil?
  • Undoubtedly, a great contribution to the consolidation and dissemination of the anaerobic technology for the treatment of domestic sewage in Brazil came from the National Research Programme on Basic Sanitation—PROSAB, which was carried from 1997 to 2007 (Chernicharo et al. 2001).
  • How much sewage should be treated in anaerobic reactor?
  • In such case, the anaerobic reactor should only treat a part of the influent raw sewage (possibly no more than 50–70 %). The remaining part (30–50 %) should be directed to the complementary biological treatment, aiming at nitrification and denitrification, so that there is enough organic matter for the denitrification step.
  • Is anaerobic treatment possible for high-strength wastewater?
  • At first, anaerobic treatment was considered possible for high-strength wastewater and only for temperature conditions above 20–25 °C so that the first anaerobic reactor configurations were applied in tropical regions and designed for industrial wastewater ( Foresti et al., 2006 ).
