The influence of the glucose addition on the rejection of organic and inorganic compounds and on the changes of the permeate flux has been studied. The feed comprised aqueous solutions of mono- and divalent salts (KCl, NaCl, K2SO4, Na2CO3 and NaHCO3) in various concentrations. The permeate flux was not changed in any solution of inorganic salts, except the solution of K2SO4, when glucose was added to these solutions. In this case, the permeate fluxes decreased by about 9-13%. The retention coefficient of total dissolved solids (for various solutions) was not affected by glucose added to the feed containing inorganic compounds. The rejection of total organic carbon in the mixture of Na2CO3 and glucose was lower by about 6% than that in glucose solution.
