Abstract

Даний винахід належить до протимікробної мембрани. Конкретніше, даний винахід належить до протимікробної мембрани, придатної для очищення питної води під дією гравітації, шляхом видалення шкідливих мікроорганізмів, які існують в джерелі вхідної води. Однією з цілей даного винаходу є розробка протимікробної мембрани з відносно тривалим терміном служби. Іншою метою винаходу є розробка способу очищення води, без утворення будь-яких побічних продуктів. Несподівано у винаході виявлено, що текстильний фільтр, просочений термопластичним полімером і галогенідом срібла, здатний утворити протимікробну мембрану, що має ультрафільтраційну властивість і тривалий термін служби; причому потрібно менше втручання споживача, не відбувається утворення будь-яких побічних продуктів і, крім того, мембрана здатна забезпечувати подачу мікробіологічно безпечної води.
