Baromembrane methods are a modern tool for implementing a number of priority areas of science, technology and engineering. One of the main problems in the use of baromembrane methods in water treatment processes is the problem of calculating one of the main parameters of these processes - osmotic pressure. For medium and high values of concentration, due to deviations of thermodynamic equations from ideality due to electrostatic forces and forces of intermolecular interaction, in the formula for calculating osmotic pressure it is necessary to enter values of activity coefficients. The
existing methods of calculation of activity coefficients are analysed in the article and the method of theoretical calculation of activity coefficients in the process of using aromembrane methods for water treatment is offered.
