Abstract

FABRICAçãO DE MEMBRANAS PARA DESSALINIZAçãO E FILTRAGEM. Uma membrana espiral é descrita que compreende uma tela alongada de um material que permite que a água passe através mas inibe a passagem de sólidos e/ou sólidos dissolvidos. A tela foi dobrada em forma de ziguezague para produzir uma pilha de camadas (68.1, 68.2, etc.) unida uma na outra por curvas reversas (72, 74) Um tubo perfurado (18) é fornecido, as extremidades da tela que formam a pilha sendo presas no tubo. A pilha é enrolada em torno do tubo e existem espaçadores (58, 62) entre as camadas (68.1, 68.2, etc.). Os espaçadores mantêm as camadas afastadas para formar passagens de fluxo de água (56, 60) . Passagens de fluxo de água alternadas (60) têm as extremidades das mesmas transversas às curvas (72, 74) vedadas fechadas. Estas passagens são também fechadas por curvas reversas (74) nas extremidades radialmente externas das mesmas. Ao longo de suas bordas radialmente internas , estas passagens estão em comunicação com as perfurações (54) do tubo (20) As fitas de estiramento (70) são fornecidas dentro das curvas (72, 74)
