  • What are the applications of organic polyelectrolytes in potable water production?
  • Introduction The main applications of organic polyelectrolytes in potable water production are in coagulation and flocculation, and in the dewatering of treatment plant sludges. The water production processes are usually followed by sedimentation and filtration, although with only slightly contaminated waters the sedimentation step may be omitted.
  • Can polyelectrolytes be used for complex industrial wastewater?
  • ion of poly-electrolytes can also be used for complex industria wastewater. Polyelectrolytes are having many advantages in water chemistry. It is quite reasonable to believe that the polyelectrolyte ith maximum charge density is used more eficiently in industrial wastewater. However more quantitative study is require
  • Which polymers are used for coagulation and flocculation?
  • Cationic polyacrylamides, ammonium-based polymers, poly (allyldimethyl-ammonium chloride) and epichlorohydrin/dimethylamine-based polymers are the most common CPEs used as coagulation and flocculation agents because they are economical and water soluble with tunable charge densities at high molecular weights.
  • Can CNTs and ferric chloride be combined in a flocculation process?
  • This study revealed that CNTs and ferric chloride had no synergetic effect, and therefore combining them in a flocculation process would not improve wastewater treatment. The feasibility of the integration of treatment systems and devices for reducing turbidity and COD values in brewery wastewater has been assessed by Simate ( 2015 ).
