Abstract

MEMBRANA DE POLI(FLUORURO DE VINILIDENO), METODO PARA SU PREPARACION Y USO DE LA MISMA EN ELEMENTOS DE FILTRACION. DICHA MEMBRANA ES ISOTROPA, SIN PIEL, POROSA, TIENE UN VALOR KUF DE AL MENOS APROXIMADAMENTE 103 KPA, Y PREFERENTEMENTE INFERIOR A APROXIMADAMENTE 345 KPA, Y TAMBIEN TIENE PREFERIBLEMENTE UNA REDUCCION DEL TITULO DE AL MENOS APROXIMADAMENTE 108 FRENTE AL BACTERIOFAGO T1, MAS PREFERENTEMENTE FRENTE AL COLIFAGO PR772, Y TODAVIA MAS PREFERIBLEMENTE FRENTE AL BACTERIOFAGO PP7. EL METODO DE PREPARAR DICHA MEMBRANA CONSISTE EN PROPORCIONAR UNA SOLUCION DE COLADA QUE COMPRENDE POLI(FLUORURO DE VINILIDENO) Y UN DISOLVENTE, CALENTAR LA SOLUCION DE COLADA A UNA TEMPERATURA UNIFORME DE APROXIMADAMENTE 57C A APROXIMADAMENTE 60C, EXTENDER LA SOLUCION DE COLADA SOBRE UN SUSTRATO PARA FORMAR UNA PELICULA, ENFRIAR RAPIDAMENTE LA PELICULA EN UN BAÑO DE ENFRIAMIENTO RAPIDO A FIN DE FORMAR UNA MEMBRANA POROSA, Y LAVAR Y SECAR LA MEMBRANA POROSA.
