Abstract

"CéLULA ELETROQUìMICA CAPAZ DE REMOVER ìONS DE UMA CORRENTE DE SOLUçãO, SISTEMA DE TROCA DE ìON ELETROQUìMICO, CONJUNTO DE CéLULAS ELETROQUìMICAS PARA REMOVER SELETIVAMENTE ìONS MULTIVALENTES DE UMA SOLUçãO, E, PROCESSOS DE SUBSTITUIçãO DE ìONS EM UM MATERIAL DE TROCA DE ìON PELA APLICAçãO DE UMA VOLTAGEM PARA UMA CéLULA ELETROQUìMICA, E DE REMOçãO DE ìONS MULTIVALENTES DE UMA SOLUçãO". Uma célula eletroquímica (20) para remoção de íons de uma corrente de solução compreende um alojamento (25) possuindo primeiro (40) e segundo (45) eletrodos. Pelo menos uma membrana de troca de íon de divisão de água (100) é posicionada entre os eletrodos, a membrana de divisão de água (100) compreendendo (i) uma superfície de trica de cátion (105) voltada para o primeiro eletrodo (40), e (ii) uma superfície de troca de ânio (110) voltada para o segundo eletrodo (45). Um caminho de corrente de solução (121) é definido pela membrana de divisão de água. O caminho de corrente de solução compreende (i) uma entrada (30) para a corrente de solução influente, (ii) pelo menos um canal que permite que a corrente de solução influente flua além de pelo menos uma superfície de membrana de divisão de água para formar uma ou mais correntes de solução tratadas, e (iii) uma saída única (35) que combina as correntes de solução tratadas para formar uma única solução efluente. Preferivelmente, o caminho de corrente de solução compreende um canal unitário e contíguo que flui além de ambas as superfícies de troca de cátion e ânio das membranas de divisão de água, e mais preferivelmente é conectada em uma suq³ência não interrompida e se estende substancialmente contínua de entrada para a saída.
