CA 2660610

A method of processing landfill leachate by use of a membrane separation process is disclosed. Specifically, the following steps are taken to process landfill leachate: collecting landfill leachate in a receptacle suitable to hold said landfill leachate; treating said landfill leachate with one or more water soluble polymers, wherein said water soluble polymers are selected from the group consisting of: amphoteric polymers; cationic polymers; zwitterionic polymers; and a combination thereof; optionally mixing said water soluble polymers with said landfill leachate; passing said treated landfill leachate through a membrane, wherein said membrane is an ultrafiltration membrane or a microfiltration membrane; and optionally back-flushing said membrane to remove solids from the membrane surface.

La présente invention concerne un procédé de retraitement des lixiviats de mise en décharge par séparation par membrane. Ce retraitement des lixiviats comprend les opérations suivantes: recueil des lixiviats de mise en décharge dans une structure de rétention appropriée; traitement de ces lixiviats de mise en décharge avec un ou plusieurs polymères hydrosolubles choisis dans le groupe des polymères amphotères, polymères cationiques, polymères zwitterioniques, et certaines de leurs combinaisons; mélange éventuel de ces polymères hydrosolubles avec le lixiviat de mise en décharge; passage du lixiviat obtenu par une membrane d'ultrafiltration ou de microfiltration; et inversion du flux pour dégager les solides de la surface de la membrane.
