  • How does biological wastewater treatment affect aquatic animals?
  • Biological wastewater treatment produces some unwanted microorganisms that produce gases and bad odor. This treated effluents containing water cannot be released into water bodies as it can cause a change in physicochemical properties of water, which ultimately leads to a decrease in the aquatic animal population.
  • 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.
  • What are the advantages of biological wastewater treatment methods?
  • Biological wastewater treatment methods are advantageous in that they can treat a wide range of pollutants and nutrients, resulting in energy/chemical generation with efficient organic removal, thereby improving the wastewater quality and reducing the environmental impact of wastewater discharge [ 40 ].
  • What are the pros and cons of biological treatment?
  • Wastewater facilities use aerobic, anaerobic or both types of microbes. The pros and cons of biological treatments depend partly on the origin of wastewater and its type of contamination and applied methods. Some methods, such as membrane filtration, subsequent to biological treatment, may improve outcomes.
