Способ получения сверхчистой воды относится к способам получения преимущественно апирогенной воды методом обратного осмоса и может быть использован в медицине, фармацевтической и других отраслях промышленности, где требуется вода, очищенная от микроорганизмов. Для повышения качества получаемой воды после ее предварительной очистки проводят концентрирование на мембране в две стадии, причем пермеат после первой стадии обрабатывают активированным углем и подают на вторую стадию, концентрат после которой возвращают на первую стадию, дезинфекцию ионами Ag+ осуществляют путем и/или диффузии ионов Ag+ через полупроницаемую мембрану, разделяющую полость с раствором AgNO3, от пермеата, отводимого после второй стадии концентрирования, или ионами Ag+, диффундирующими из слоя серебра, нанесенного на внутреннюю поверхность пермеатотводящего канала второй стадии. Поверхность пермеатотводящего канала, покрытия слоем серебра, составляет 30 - 90% от всей внутренней поверхности пермеатотводящего канала. В качестве полупроницаемой мембраны используют гидрофильную мембрану с размером пор

.The method of obtaining ultrapure water refers to the methods of obtaining predominantly pyrogen-free water by the method of reverse osmosis and can be used in medicine, pharmaceutical and other industries that require water purified from microorganisms. To improve the quality of the water produced after its preliminary purification, the concentration is carried out on the membrane in two stages, with the permeate after the first stage being treated with activated carbon and fed to the second stage, after which the concentrate is returned to the first stage, disinfection with Ag + ions is carried out by and / or diffusion of ions Ag + through a semipermeable membrane separating the cavity with a solution of AgNO 3 from the permeate withdrawn after the second concentration step, or Ag + ions, diffusing silver layer deposited on ext nnyuyu surface permeatotvodyaschego channel second stage. The surface of the permeato-withdrawal channel, which is coated with a layer of silver, makes up 30–90% of the entire inner surface of the permeat-withdrawing channel.
