  • Can wastewater treatment alternatives reduce the energy demand in municipal WWTPs?
  • Through a comparative analysis of wastewater treatment alternatives, it becomes evident that transitioning from the CAS system to other options can significantly reduce the energy demand in municipal WWTPs from 42 to 27 kWh (cap. a) −1.
  • What is biological nutrients removal process in municipal wastewater treatment?
  • Biological nutrients removal process, i.e., anaerobic-anoxic–oxic, was the prevalent municipal wastewater treatment technology across the world. Nevertheless, additional carbon sources were required to acquire a good effluent quality when treating low organic strength municipal wastewater.
  • Can a single treatment unit remove carbon and phosphorus from municipal wastewater?
  • In such single treatment unit, the simultaneous removal of carbon and phosphorus from simulated municipal wastewater could then be achieved, and the COD and TP contents in the treated wastewater could readily meet the China Class 1A discharge standard.
  • What substances are used in wastewater treatment?
  • Substances derived from plants, animals, and microorganisms have garnered significant attention in the realm of wastewater treatment because of not having toxic effects on aquatic ecosystems and their effectiveness removing suspended solids. Examples include starch, tannin, Moringa oleifera, and chitosan ( Nimeshal et al., 2025 ).
