  • What is biological wastewater treatment?
  • Biological wastewater treatment is widely used to remove/recover organic pollutants and nutrients from a diverse wastewater spectrum. However, conventional biological processes face challenges, such as low efficiency, high energy consumption, and the generation of excess sludge.
  • What are the challenges and opportunities for biological wastewater treatment?
  • Challenges and opportunities for biological wastewater treatment include the optimization of process design and operation with single or integrated processes to achieve higher efficiency, lower cost, and lower energy consumption.
  • Is biological wastewater treatment eco-friendly?
  • Several wastewater treatment processes include physical, chemical and biological techniques. During biological treatment, waste water is treated using micro-organism instead of chemicals. Hence, these methods are relatively more eco-friendly. However, biological treatment organic pollutants but not all kinds of pollutants (Hussain et al., 2021).
  • Can waterfall aeration biofilm reactor and SBR be used in wastewater treatment?
  • Li et al. (2021) used a combination of waterfall aeration biofilm reactor with SBR for the treatment of wastewater having C/N ratio of 50. Different types of filters were used in the combination leading to COD removal efficiency of 99%, 97–99% and 96–99% respectively.
