A osmose inversa (OR) \u00e9 um processo que utiliza a press\u00e3o hidr\u00e1ulica para empurrar a \u00e1gua atrav\u00e9s de uma membrana semiperme\u00e1vel, que remove os constituintes dissolvidos da \u00e1gua<\/p>\n

. Os sistemas de membranas de alta press\u00e3o, como a OR, s\u00e3o normalmente utilizados para este fim<\/p>\n

. A diferen\u00e7a entre as membranas de alta press\u00e3o e de baixa press\u00e3o reside na press\u00e3o aplicada. A RO padr\u00e3o funciona a 195 psig, enquanto os elementos de baixa press\u00e3o\/baixa energia (LP\/LE) funcionam a 115 psig<\/p>\n

. A osmose inversa de alta press\u00e3o utiliza uma press\u00e3o hidr\u00e1ulica superior \u00e0 press\u00e3o osm\u00f3tica da solu\u00e7\u00e3o para conduzir o transporte de \u00e1gua atrav\u00e9s de uma membrana semiperme\u00e1vel
\nA principal diferen\u00e7a entre as membranas de alta press\u00e3o e de baixa press\u00e3o \u00e9 a press\u00e3o de funcionamento. As membranas de baixa press\u00e3o funcionam a press\u00f5es que variam entre 10 e 30 lb\/pol. (psi), enquanto as membranas de alta press\u00e3o, incluindo a nanofiltra\u00e7\u00e3o, funcionam a press\u00f5es que variam entre 75 e 250 psi[1][2]. A filtra\u00e7\u00e3o por membranas de alta press\u00e3o requer press\u00f5es internas de 1000 psi (70 bar) ou superiores, enquanto as unidades de microfiltra\u00e7\u00e3o de baixa press\u00e3o requerem press\u00f5es inferiores a 15 psi (1 bar)[3]. Al\u00e9m disso, as membranas de alta press\u00e3o s\u00e3o normalmente utilizadas em sistemas de osmose inversa (OR), que requerem uma membrana estanque que retenha quase todas as esp\u00e9cies dissolvidas, incluindo a\u00e7\u00facares e sais[3].
