UVM Reference Number: C642
Summary:
Multi-functional membrane to prevent biofouling during water purification processes
Background:
As the need for more sources of drinkable water increases, there is a strong interest in developing more advanced water purification technologies. During long term use, water purification membranes are susceptible to biofilm formation, clogging the membranes, reducing the effective life of the membrane and putting water supplies at risk.
Technology Overview:
This technology is a multi-functional membrane to prevent biofouling during water purification processes. The membrane is functionalized with antibacterial nanoparticles and anti-quorum sensing technology in a two-prong approach to preventing bacterial contamination and biofilm establishment on the membrane. The technology is inexpensive, non-toxic and more effective that current technologies in preventing biofouling.
