Compositions and Methods for Improving the Anti-Fouling Properties of Polyethersulfone Membranes

Compositions and Methods for Improving the Anti-Fouling Properties of Polyethersulfone Membranes
Inventors: Shane Walker, Eva Deemer, Tallen Capt
Patent No. 10,525,420

Description:
This patent application embodies GO as an antifouling agent in polyethersulfone membranes. Increasing GO concentration can increase viscosity leading to reduced pore radius and porosity and consequently reduced pure water flux. In addition, GO also increases the hydrophilic nature of the nanocomposite filter, allowing a greater pure water throughput.

Abstract:
The present invention includes a treatment system and methods for removing waste or other agents from a fluid stream, the system comprising: an inlet flow path for receiving a fluid stream from a source outside the treatment system; a vessel for containing the fluid stream, the vessel comprising a permeable filter configured for biological and physical treatment of the fluid stream, the filter comprising one or more nano-thin film or polymer composite layers of carbon materials assembled in sp2 hybridized structures comprising carbon-carbon bonds, wherein the waste or agent is removed as it flows through pores in the film composite; and a drain fluidly connected to the vessel for discharging treated fluid stream from the vessel from which the waste or agents have been removed.
