A common problem in separation, fractionation and water treatment is the development of methods
for modifying industrial PAN membranes to prevent biological contamination, including the
formation of biofilm on the surface of the membrane, and prolong their use. We describe the
method of formation of polyacrylonitrile membranes with antibacterial properties by addition into
the casting polymer solution of antibacterial polymeric compounds: polyhexamethyleneguanidine
chloride, oligourethanesemicarbazide with terminal cationic pyridinium chloride groups, and the
polyvinylpyrrolidone-iodine complex. We investigated the effect of the addition of antibacterial
compounds to the casting solution on the physicochemical, transport and antibacterial properties of
the obtained membranes. We show that increasing the concentration of the bactericidal additives in
the casting solution to 3% (wt.) leads to a change in the investigated physicochemical
characteristics, water flux and membrane rejection of polyethyleneglycol and low molecular weight
electrolyte type 2-1 (CaCl2). We found that membranes prepared from the polymer solution with 3%
(wt.) of antimicrobial substances are characterized by high antibacterial activity up to 50 days.
