  • Why is pdadmac used in the Palermo aqueduct?
  • The Palermo aqueduct is using PDADMAC in an experimental phase, in order to promote sludge dehydration, obtaining excellent results. The water derived from the sludge thickening process is added to the raw water to be treated and this could lead to the possible presence of monomer traces in the water supplied to the users.
  • How do pdadmac-Paa N Polyelectrolyte films behave?
  • Surprisingly, fresh exponentially grown (PDADMAC–PAA) n polyelectrolyte films behave as glassy materials with Young moduli as large as 2 MPa. Their organization is governed by a competition between PDADMAC–PAA electrostatic interactions and water stabilization of PAA charges that limits association between polycationic and polyanionic chains.
  • Are polyelectrolyte-modified membranes suitable for organic pollutant removal?
  • Organic pollutant removal Polyelectrolyte-modified membranes are also extensively adopted for the removal of organic solutes (e.g., micropollutants) in water.
  • 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).
