Abstract

método e aparelho para a pur!f!cação de agua contendo metal a presente invenção refere-se a um método para a purificação de água contendo um metal que é capaz de reduzir o esforço desnecessário imposto pelo tratamento da água concentrada produzida por meio de uma separação por membrana de osmose reversa. é proporcionado um mêtsdo para a purificação de água contendo metal com um componente de metal dissolvido na mesma o qual realiza uma etapa de separação por membrana de osmose reversa para separar a água que contem metal em água purificada que é permeada e concentrada por meiq de uma separação de osmose reversa. o método adicionalmente realiza uma etapa de eletrólise do material concentrado para prod.u~ir água alcalina a partir do lado de catodo; e uma etapa de separação da água concentrada para separação por filtragem de um c:qmpohente de metal, o qual foi precipitado por meio de alcalin.i.2ação a partir da água alcalina produzida pela etapa de eletrólise.The method and apparatus for purifying metal-containing water The present invention relates to a method for purifying metal-containing water which is capable of reducing the unnecessary effort imposed by treating concentrated water produced by a reverse osmosis membrane separation. A method for purifying metal-containing water with a metal component dissolved therein is provided which performs a reverse osmosis membrane separation step to separate the metal-containing water into purified water which is permeated and concentrated by means of one. reverse osmosis separation. The method further performs an electrolysis step of the concentrated material to produce alkaline water from the cathode side; and a concentrated water separation step for filtration separation of a metal solvent which was precipitated by alkalinisation from the alkaline water produced by the electrolysis step.
