A process of flocculating and dewatering an aqueous suspension of suspended solids comprising, introducing into the suspension, (a) a concentrated polymer solution and, (b) a dilute polymer solution, characterised in that the concentrated and dilute polymer solutions are introduced into the substrate substantially simultaneously. Preferably the concentrated and dilute polymer solutions are introduced into the suspension as an aqueous composition comprising a dilute aqueous solution of polymer and a concentrated solution of polymer. The process brings about improvements in filtration and cake solids.
Procédé de floculation et de déshydratation d'une suspension aqueuse composée de solides en suspension, ce qui consiste à introduire dans la suspension : (a) une solution polymère concentrée et (b) une solution polymère diluée. Ce procédé est caractérisé par le fait qu'on introduit les solutions polymères concentrée et diluée dans le substrat pratiquement simultanément. On introduit, de préférence, les solutions polymères concentrée et diluée dans la suspension sous forme de composition aqueuse comprenant une solution aqueuse diluée de polymère et une solution concentrée de polymère. Ce procédé apporte des améliorations en ce qui concerne la filtration et les solides en pain.
