Changing of mechanisms of self-diffusion of water molecules under nanofiltration of electrolyte solution

A nanofiltration membrane OPMN-KM3 has been used for study. Initial concentration of calcium chloride in a solution was 1.311 mmol/l. Concentration of this substance in a filtrate was 0.836 mmol/l. As a result of the complicated processes occuring during filtration of the solution through the membrane it has been established that mechanisms of water molecules self-diffusion changed in comparison with a solution of the same concentration which was not under the membrane treatment.
