CNT-based nanoporous membranes with high flux for energy-efficient treatment of wastewater and process waters from natural gas and crude oil processing industries

Carbon nanotubes (CNT) represent an important group in the class of carbon-based nanomaterials. Their physical characteristics make them highly suitable for use in filtration methods, and lab-scaled applications have been very promising. However, large-scale CNT-based nanoporous membranes for application in industrial processes are not yet available.

The objective of the present project is the development of CNT-based membranes allowing a high flux for treatment of wastewater and process waters from metalworking, natural gas and crude oil processing industries. Three basic composites are investigated: CNT/polymer, CNT/ceramic and CNT/carbon membranes. For all three composites, process parameters will be evaluated. Additionally, the ecotoxicological risk of the composite membranes and the treated process waters and wastewaters will be investigated with a set of ecotoxicity tests. The results of the ecotoxicological tests will be considered in the further development of suitable filtration methods, contributing to the sustainability of wastewater and process water treatment.
