  • What is PolyDADMAC used for?
  • PolyDADMAC was the first polymer to be permitted for the use in potable water treatment by Food and Drug Administration of U.S.A [ 25 ]. It has also been used in industrial applications such as flocculation, dewatering, coagulation, separation processes [ 26, 27 ], and other applications [ 28, 29 ].
  • Is PolyDADMAC a cationic polymer?
  • PolyDADMAC is usually delivered as a liquid concentrate having a solids level in the range of 10 to 50%. It is a high charge density cationic polymer. The charge density makes it well suited for flocculation.
  • How to remove unreacted PolyDADMAC from water treatment plants?
  • A normal practice for the removal of unreacted polyDADMAC by water treatment plants is done by adsorption of the polyelectrolyte by sand filters (Nozaic et al. 2000 ). An experiment was carried out to find out the sorption capacity of sand on this cationic polyelectrolyte using the developed method.
  • What conditions affect the stability of polyDADMAC with water treatment chemicals?
  • The results obtained for stability studies of polyDADMAC with water treatment chemicals such as chlorine, different conditions of pH, temperature and UV radiation are presented. Changes in the polymer structure was followed by GPC, HPLC and GC-MS and the results indicate that the product is affected by the above conditions.
