  • Can tertiary water treatment technologies be used to purify water?
  • Besides, Ortiz et al. have established a life cycle assessment of water treatment technologies for wastewater and water reuse in a small town. Some possible additional tertiary treatments have been allowed water reuse to purify water, such as conventional activated sludge system, UF, and membrane biological reactors.
  • What are the applications of sewage treatment in developing countries?
  • Possible applications in developing countries include the direct treatment of raw sewage, particularly in rapidly growing megacities, and the extraction of valuable resources from sewage, namely clean water, nutrients (mostly N and P), and energy.
  • Is LCA a decision support tool for urban wastewater reuse?
  • Meneses M, Pasqualino JC, Castells F (2010) Environmental assessment of urban wastewater reuse: treatment alternatives and applications. Chemosphere 81:266–272 Pasqualino JC, Meneses M, Abella M, Castells F (2009) LCA as a decision support tool for the environmental improvement of the operation of a municipal wastewater treatment plant.
  • Can recycled water be used as a tertiary treatment?
  • The tertiary treatment process for recycled water has been shown in Fig. 12. The research suggests that non-potable uses (both agricultural and urban uses) of reclaimed water have environmental and economic advantages. Reuse of treated wastewater is particularly beneficial when it can replace desalinated water.
