Abstract: Production of bioproducts is associated with the generation of considerable amounts of effluents from the bioreactors used. Application of the nanofiltration process was proposed for the treatment of these effluents in order to separate both inorganic and organic solutes. Composition of the fermentation broth precludes the utilization of traditional spiral-wound modules (high turbidity) for the solutes separation in the NF process. The tubular module with AFC30 membranes applied in this work enables such a possibility. Transport and separation characteristics of the NF membrane were determined for the reference solutions containing components present in the effluents generated during the fermentation of glycerol with the use of bacteria.
Keywords: nanofiltration – organic and inorganic solutes – tubular membrane – fermentation broth – glycerol
