Upcycling of Used RO Membranes

Technology / Service Summary


Recycling of used RO for reducing the membrane waste and use it for the other applications such as industrial wastewater reclamations.


Polymer can be coated on the membrane with non-destructively. The polymer-coated membrane showed good performance of antibiotic function and oil repellency.


70% reduction of biofilm formation and 30% increase of oil repellency.
