  • What is coagulation–flocculation treatment process?
  • Coagulation–flocculation process is regarded as one of the most important and widely used treatment processes of industrial wastewaters due to its simplicity and effectiveness. This paper provides a critical review on recent studies of coagulation–flocculation treatment processes of various industrial wastewaters.
  • How to improve flocculation and sludge settling in the WWTP?
  • A common practice to enhance flocculation and sludge settling in the WWTP is to dose chemical coagulants. Coagulation is fast acting and improvements in effluent quality can be quickly observed. However, there are limitations to coagulation; water pH and hardness are two parameters that affect the efficiency of chemical coagulation.
  • How to improve raw water flocculation characteristics?
  • In future research, a mathematical model and a stability model for enhanced coagulation should be established, flocculants should be developed, appropriate coagulation nodules should be selected, and different water qualities, preoxidation or ultrasonic methods can be considered to improve raw water flocculation characteristics.
  • What is biological flocculation?
  • Biological flocculation is the ability exhibited by microorganisms to spontaneously form large, dense and quick settling flocs. Therefore, biological wastewater treatment processes are geared towards the cultivation of floc-forming and fast settling microorganisms.
