Abstract

Способ обработки воды обратной промывки с использованием процесса мембранного разделения, который включает сбор воды обратной промывки в приемную емкость, пригодную для удержания воды обратной промывки, обработку указанной воды обратной промывки одним или более растворимыми в воде катионоактивными полимерами, в которых плотность заряда составляет от 5 мол. % до примерно 100 мол. %, и пропускание обработанной воды обратной промывки через мембрану, которая является ультрафильтрационной мембраной.
