Nanocarbon Immobilized Membrane for Bacterial Deactivation and Endotoxin Removal Via Membrane Distillation
Patent
Overview
Overview
abstract
Direct contact membrane distillation (DCMD) was used to generate high purity water from bacteria and endotoxin-contaminated water. The DCMD system includes a nanocarbon-coated membrane. Exemplary nanocarbon-coated membranes include a layer of carbon nanotubes immobilized relative to a polytetrafluorethylene surface (CNIM), a layer of carboxylate functionalized carbon nanotubes immobilized in the PTFE (CNIM-COOH), and a layer of graphene oxide immobilized in the PTFE (GOIM). The nanocarbon-immobilized membranes are effective in generating ultrapure, medical grade water.
