Las características de la tecnología de membrana de ósmosis inversa

Ⅰ. ¿Qué es la tecnología de membrana de ósmosis inversa?

La tecnología de membrana de ósmosis inversa (tecnología de membrana RO) es una tecnología de separación y filtración de membrana que utiliza la diferencia de presión como fuerza impulsora. Su tamaño de poro es tan pequeño como nanómetros (1 nanómetro = 10-9 metros). Bajo presión, las moléculas de H2O pueden pasar a través de las membranas del RO, mientras que las sales inorgánicas en el agua de la fuente, impurezas tales como iones de metales pesados, materia orgánica, coloides, bacterias, Y los virus no pueden pasar a través de la membrana RO, por lo que el agua pura permeable y el agua concentrada impermeable se distinguen estrictamente. El Dispositivo de ósmosis inversa se compone principalmente de una bomba de alta presión, una membrana de ósmosis inversa y una parte de control. La bomba de alta presión presuriza la fuente de agua. Excepto por las moléculas de agua que pueden pasar a través de la membrana RO, otras sustancias en el agua (minerales, materia orgánica, microorganismos, etc.) son casi todas rechazadas por la membrana, que no puede pasar a través de la membrana RO y ser lavada por agua concentrada a alta presión.

La tecnología de membrana RO es actualmente la tecnología de desalinización más utilizada en la preparación de agua de alta pureza. Sus objetos de separación son compuestos orgánicos con una variedad de iones en la solución y pesos moleculares de varios cientos. Las tecnologías de ósmosis inversa (RO), ultrafiltración (UF) y membranas microporosas Tanto la filtración (MF) como la electrodiálisis (ED) son tecnologías de separación de membranas. Como proveedor líder de membrana cerámica en China, Jiuwu Hi-Tech se ha centrado en la investigación y el desarrollo de tecnología de membrana cerámica avanzada.

Sucer. ¿Cuáles son las características de la tecnología de membrana RO?

Características de la tecnología de membrana RO:

1. La Tasa de desalinización de ósmosis inversa es alta. La Tasa de desalinización de una sola membrana puede alcanzar 99%. La velocidad de desalinización de un sistema de ósmosis inversa de una sola etapa puede ser generalmente estable por encima de 90%, y la tasa de desalinización de un sistema de ósmosis inversa de dos etapas puede ser generalmente estable por encima de 98%.

2. Debido a que la ósmosis inversa puede eliminar eficazmente microorganismos como bacterias, materia orgánica y sustancias inorgánicas como elementos metálicos, la calidad del agua efluente es mejor que otros métodos.

3. El costo de operación y el costo de mano de obra del agua pura producida por ósmosis inversa son bajos, reduciendo la contaminación ambiental.

4. La tecnología de membrana RO ralentiza el cambio de la calidad del agua producida causada por la fluctuación de la calidad del agua de la fuente, lo que conduce a la estabilidad de la calidad del agua en la producción, que tiene un efecto positivo en la estabilidad de la calidad del producto de agua pura.

5. Puede reducir en gran medida la carga del equipo de procesamiento posterior, prolongando así la vida útil del equipo de procesamiento posterior.

En los últimos 30 años, la ósmosis inversa, la electrodiálisis, La ultrafiltración y la filtración de membrana han entrado en aplicaciones industriales y se han desarrollado rápidamente. En semiconductores, procesos de fabricación de circuitos integrados, industrias alimentaria y farmacéutica, la tecnología de membrana de ósmosis inversa generalmente se utiliza como clave en la preparación de agua de alta pureza. La desalinización y La ultrafiltración se utilizan principalmente como postratamiento de sistemas de producción de agua, mientras que la filtración de membrana se utiliza para pretratamiento y postratamiento de Tratamiento de Agua Para filtrar partículas y bacterias.
