Project Description and Objectives
The extractive membrane bioreactor (EMBR) is an alternative, relatively new technology for dealing with wastewaters, which employs a combination of membrane extraction and biodegradation to remove and destroy the toxic organic molecules. In this process, the targeting toxic organics could transfer from the waste stream to the biological zone where they are degraded, while the inorganic composition of the biomedium can be controlled completely independently of the inorganic composition in the wastewater zone. These features could be attributed to the special properties of membrane materials: polydimethylsiloxane (PDMS), which make EMBR very suitable in the disposal of the wastewater with strong acid, strong alkali, high salinity and biological toxic substances. However, the relative poor selective permeability and low flux inhibit the further application of EMBR technology.
In this study, the novel extractive PDMS membranes created by electrospining technologies will be prepared and its performance in EMBR will be evaluated.
Preparation and characterization of the superhydrophobic electrospun nanofiber membranes;
Evaluation of membrane performance of the fabricated membrane
