  • 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.
  • What are organic polyelectrolytes?
  • Polyelectrolytes are those polymers which are water soluble and carrying ionic charge. Organic polyelectrolytes were introduced into environment engineering because of its potentials. Polyelectrolytes are used successfully in water and wastewater treatment (Lee et al. 1998).
  • Can polyelectrolytes be used with inorganic coagulants?
  • So, organic polyelectrolytes were introduced in conjunction with inorganic coagulants for the treatment of water and wastewater. The optimum dosage of polyelectrolytes in all kinds of water and industrial wastewater can be very low if it will be used in conjunction with inorganic coagulants.
  • Can cationic polyelectrolytes remove nom from water?
  • Another very important potential application is the removal of NOM from water, which can be achieved by cationic polyelectrolytes. In natural waters, most organic matter is in the form of humic substances, which are essentially natural anionic polyelectrolytes covering a range of MW and of rather complex structure.
