SiC membranes are used in many industrial fields with high performances and good retention efficiency in the filtration of loaded liquids such as wastewater, oil or wine. Technologies allow to characterise membrane’s surface but few allow the characterisation of its depth. This paper proposes the combination of results obtained by the usual techniques of porous materials and by 3D X-ray tomography characterisation. A morphological analysis of solid and porous phase is carried out on the total thickness of the membrane. Combination of results on all layers is relevant for the study of SiC membranes, showing not only the SiC surface properties but also the 3D description of the porous material (i.e. support, layer and skin). The definition of essential parameters to define the efficiency of a filtration such as hydrophobicity, porosity and tortuosity allows to justify the use and superior performance of SiC membranes for the filtration of loaded liquids.

In a winery, clarification and stabilization steps by crossflow microfiltration are limited by fouling phenomenon which reduces production flows and can alter the aromatic potential of wines, forcing professionals to use several successive filtration steps. The objectives of this industrial-scale study are to (i) introduce SiC membranes at different vinification steps (ii) evaluate the hydraulic and retention performances of SiC membranes and (iii) carry out a comparative study between SiC membranes and polymeric hollow fibers commonly used in the wine industry. It appears that SiC membranes are able to filter diverse matrices with very satisfactory production flow and retention efficiency. This particular process was optimized by developing an efficient regeneration protocol. The clarification and stabilization of the matrices by SiC membranes allowed (i) the production of clear and brilliant wines, (ii) the retention of wine microorganisms, (iii) higher production flows than hollow fibers, while conserving wines interest compounds, (iv) and the filtration of matrices that cannot be processed by hollow fibers.

Unfiltered wine is a turbid medium that is not generally accepted by the consumer. Therefore, one or several filtration steps are required before bottling. Silicon carbide (SiC) membranes desirable parameters (porosity, tortuosity fluxes) allow filtering several different types of loaded matrices like wine or residue sediment. An in-depth filtration study was carried out on white and red wines to evaluate membrane efficiency and to optimise their cleaning procedure. Retention rates were studied as a function of wine type, filtration mode, and volumetric concentration factor. Compared to ceramic membranes, SiC membrane permeate fluxes are higher, up to a factor of 10 for red wine. For white wines, equivalent permeate fluxes could be obtained with dead-end filtration. Moreover, SiC membranes appear to be effective in obtaining a clear and brilliant wine and do not modify the concentration of the compounds of interest in wine. Finally, an optimised cleaning protocol has been identified and shown to restore a sufficient permeability to the SiC membranes.
