Hydrodynamics of flow of a solution in a membrane channel were investigated and a criterion equation was obtained to determine the structural coefficients of flow. A method was developed that takes into account the hydrodynamics of flow, which allows to determine the technological parameters of the membrane installation. A quantitative calculation was performed to determine the working area, the number of elements, pressure losses and pump head for roll-type elements ERO-e-6.5/900А and ERO-K-92-475 in reverse osmosis separation of different industrial solutions.
