Abstract

Настоящее изобретение относится к способу удаления катионов из воды и установке для осуществления указанного способа. Способ удаления катиона(ов) из воды, содержащей катион(ы), выбранные из группы, состоящей из Se, As, Sb, Cr, Mn, Mo, W, V, Te, P, Si, включает: a) получение суспензии, содержащей осадок железа, путем электрохимической обработки воды, где воду пропускают через блок для электрохимической обработки воды, в котором под действием электричества железо с анода растворяется в воде, образуя при этом суспензию, содержащую осадок железа, в которой адсорбируются/соосаждаются удаляемые катионы, c) выделение твердых веществ из полученной суспензии с получением при этом обработанной воды со сниженным содержанием катионов и твердых веществ, содержащих соединения осадка железа и соединения адсорбированных/соосажденных катионов.
