Abstract
Procedimiento que permite evitar o reducir la obstrucción de las membranas de filtración utilizadas particularmente en el tratamiento de efluentes tales como aguas residuales, caracterizado porque consiste en añadir al efluente a filtrar, un adsorbente orgánico natural destinado a atrapar las moléculas y partículas que obstruyen las membranas de filtración.
Claims (8)
1. Procedimiento que permite evitar o reducir la
obstrucción de las membranas de filtración utilizadas
particularmente en el tratamiento de efluentes tales como aguas
residuales, caracterizado porque consiste en añadir al
efluente a filtrar, un adsorbente orgánico natural destinado a
atrapar las moléculas y partículas que obstruyen las membranas de
filtración.
2. Procedimiento según la reivindicación 1,
caracterizado porque el indicado adsorbente está constituido
por un copo biológico que presenta una concentración media en
materias secas inferior o igual a 2 g/l.
3. Procedimiento según la reivindicación 2,
caracterizado porque el indicado copo biológico está
constituido por los lodos biológicos que proceden río arriba de la
instalación de filtración membranar.
4. Procedimiento según la reivindicación 2,
caracterizado porque el indicado copo biológico está
constituido por lodos biológicos que proceden río arriba de una
estación de tratamiento distinta, pudiendo estos lodos ser
inyectados particularmente en estaciones de potabilización
fisicoquímica, para la producción de agua potable a partir de agua
dulce, de agua salobre o agua de mar.
5. Procedimiento según una cualquiera de las
reivindicaciones 2 a 4, caracterizado porque el copo
biológico se introduce directamente en la cuba de filtración.
6. Procedimiento según una cualquiera de las
reivindicaciones 2 a 4, caracterizado porque el copo
biológico se introduce en el efluente a filtrar, antes de la
membrana de filtración.
7. Procedimiento según una cualquiera de las
reivindicaciones anteriores, caracterizado porque la
alimentación del copo biológico se realiza de forma continua.
8. Procedimiento según una cualquiera de las
reivindicaciones 1 a 6, caracterizado porque la alimentación
del copo biológico se realiza de forma discontinua.
