Summary:The high-resolution low-frequency induction dielcometria method was used to compare the degrees of purity of the tap water (St. Petersburg, Russia) obtained by various methods currently in use: steam distillation, bidistillation, as well as membrane distillation separately and combined with deionization. It has been determined that all the above methods of water purification do purify water with sufficient quality, but only bidistillation and deionization produce water that does not contain ionic impurities in the order of 10–7 M.
