Abstract

Purpose: Ceramic membranes are recognized for their high mechanical strength and satisfactory acid/alkaline resistance. The innovation of this paper is the preparation of ceramic membrane carriers using cost-effective raw materials gangue and loess as well as oak powder (pore forming agent) and carboxymethyl cellulose (CMC) (binder). These materials are processed through extrusion molding and solid particle sintering to create the supports. In addition, with tetraethyl orthosilicate (TEOS) as the precursor, SiO2 thin film was prepared via the sol–gel method, and the support and thin film were modified via the dip coating method to obtain the modified hydrophobic composite ceramic film. In this study, the oil removal rate of the best ceramic membrane reached 94.1%, the oil­–water flux was 1091.3 L/(m2·h·MPa), and the membrane flux recovery rate was greater than 98%, which provided ideas for the resource utilization of industrial waste and the application of a ceramic membrane in the field of water treatment.


Keywords: Ceramic membrane support, SiO2 films, Membrane modification, Performance research.
