  • Does bridging flocculation of dispersed Silica Nanoparticle-augmented polymer solution increase or decrease?
  • The findings show that bridging flocculation of dispersed silica nanoparticle-augmented polymer solution increases with nanoparticle concentration, nanoparticle diameter, the charge of electrolyte, and electrolyte concentration. In contrast, it decreases with an increase in pH and polymer concentration.
  • Is coagulation/flocculation a viable method for water clarification?
  • Consequently, water clarification using sedimentation alone is an unfeasible approach and a new functional approach, known as coagulation/flocculation, that enhanced the settling rate of the dispersed fractions of the aqueous system was developed.
  • What is coagulation/flocculation?
  • This process is experimental and the keywords may be updated as the learning algorithm improves. Coagulation/flocculation (CF) is a two-stage process that involves the destabilization and agglomeration of dispersed, dissolved, colloidal and suspended particles in the dispersion medium.
  • Which polymeric coagulants are used in CF operations?
  • Polymeric coagulants whose cationic properties are expressed only in acidic medium and considered weak polyelectrolyte are also used. Examples of cationic polyelectrolytes that have been used in CF operations include poly (diallyldimethyl ammonium chloride), epichlorohydrin/dimethylamine polymers, cationic polyacrylamides, etc.
