      Effect of Multivalent Salts—Calcium and Aluminum on the

      Analysis results indicate that the specific adsorption of Ca 2+, Al 3+ and their hydroxo complexes on anionic PAM causes the loss of anionic character in the low pH range and leads to a low flocculation efficiency. In the high pH range, the poor kaolin flocculation can be attributed to precipitation of calcium and aluminum hydroxides on active ...

      The conformation of acrylamide/acrylate copolymers' aqueous solutions is known to be affected by the presence of cations to varying degrees. Such effects are expected to be reflected in the flocculation activity of the polymer solutions, but the published literature in this area is far from convincing, particularly on the influence of divalent cations.

      Flocculants: The First Step to Cleaner Water! - Lesson

      Flocculants—The tiny size and surface charge of colloids (small charged particles) make them difficult to remove from water, so engineers turn to flocculation. Flocculation is now an essential step in many water purifications systems as a means to remove suspended solids. This essential step is done before filtration in order to avoid clogging.
