Abstract The presented studies have been undertaken in order to investigate possibilities of applying ultrafi ltration for treatment of salted water produced in fi sh processing industry. The results could be a basis for elaboration of a treatment technology enabling recycling of both regenerated salted water and proteins, thus decreasing water use and wastewater discharge by closure of water loops [Afonso, Borquez, 2002; Kuca, Szaniawska, 2009a,b]. Development of membrane processes for waste brine purifi cation requires studies on model solutions of individual proteins including analysis of the membrane selectivity and performance. The model proteins were selected taking into account molecular weight range of fi sh proteins and their solubility in water and solutions of low and high ionic strength. One of the basic groups of proteins found in fi sh, in respect of their behavior in solvents, are proteins soluble in water and dilute, neutral salt solutions. These include albumins representing approximately 30% of the total protein content in fi sh meat. Due to the unavailability of fi sh albumin the most commonly applied bovine serum albumin was used. In the fi rst step of the present research the assessment of operating parameters infl uence on permeability in ultrafi ltration processes of aqueous bovine serum albumin (BSA) solutions using laboratoryscale membrane installation working in pseudo-cross-fl ow regime was performed.
