  • Does flocculation strategy work in water treatment?
  • As the interest in application of flocculation strategy for water treatment has grown gradually, a number of review articles related to the flocculation process have been published in recent years. Table 2 lists selected review articles with their focus related to the flocculation process in water treatment.
  • Does floc water content affect treatability?
  • Beyond the basic requirements of minimum size and surface nature to enable effective trapping on a collecting surface, field data indicate that floc water content affects treatability (as gauged by the hydraulic loading rate or treatment rate).
  • What particles are removed from raw water by coagulation and flocculation?
  • The particles being removed from raw water by coagulation and flocculation are either suspended or colloidal and are composed of clay and other inorganic materials, organic substances, bacteria, viruses, and even color.
  • 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.
