Ceramic membranes made from silicon carbide (SiC) have
recently been certified for use in the food industry, and according to
the manufacturer these membranes are extremely hydrophilic,
thus very efficient in oil/water separation. Besides this, they are
chemically inert and tolerate high salt content and temperature.
With these properties, ceramic membranes might offer a better
separation of the herring brines, compared to traditional synthetic
polymer membranes. One serious problem in UF is membrane
clogging and pre-treatment is therefore usually required
