  • Treatment of clay or dredged sediment with polymer increases adsorption characteristics
    Patent number: 9623455
    Abstract: The disclosure relates to the field of lining materials which are used to isolate landfill sites in order to avoid pollution of surrounding soil by ions such as heavy metals. Further disclosed is a process to increase the ion adsorption capacity of clay or dredged sediment. More specifically, the disclosed is a process comprising: a) mixing the clay or dredged sediment with an anionic polymer, and b) subsequently drying the mixture, results in a lining material having superior ion adsorption characteristics.
    Type: Grant
    Filed: September 6, 2013
    Date of Patent: April 18, 2017
    Assignee: Universiteit Gent
    Inventor: Gemmina Di Emidio
  • Clayey barriers
    Patent number: 9328216
    Abstract: The present invention relates to improved clayey barriers, such as compacted clay liners or geosynthetic clay liners, which can be used, among other uses, to isolate waste liquids from the environment. More in particular, the present invention relates to clay which is treated with an anionic polymer and is subsequently dehydrated before it is used as a barrier. The latter improved clays are surprisingly well, and for a long term, protected from chemical attack by aggressive electrolyte solutions present in, for example, sea water or waste liquids.
