Abstract:
The present invention is a water processing method comprising the steps of separating boron-containing water in a reverse osmosis membrane module to provide a permeated water and subjecting a part of the obtained permeated water to boron removal using an adsorbent, wherein the water subjected to the boron removal is mixed with the water not subjected to the boron removal of the permeated water to provide a mixed water. The present invention provides economic water processing method and apparatus that remove the boron from boron-containing water.
Abstract:
Elemento de membrana en espiral de ósmosis inversa (10), caracterizado porque: una pluralidad de membranas de ósmosis inversa en forma de bolsa (2), elementos de paso de líquido filtrado (3) dispuestos en el interior de dichas membranas de ósmosis inversa (2), y una pluralidad de elementos de paso de líquido de alimentación (4) intercalados entre las dichas membranas de ósmosis inversa (2) están enrollados alrededor de una superficie externa de un tubo hueco (1) de modo que sólo los interiores de dichas membranas de ósmosis inversa (2) comunican con orificios de paso (1a) formados en la superficie de dicho tubo hueco (1); cada uno de los dichos elementos de paso de líquido de alimentación (4) es un elemento en malla que tiene una serie de mallas cuadriláteras formadas por una pluralidad de elementos lineales que se cruzan; dos puntos opuestos de convergencia (7c, 7d) sobre cuatro puntos de convergencia (7c, 7d, 7e, 7f) de cada una de dichas mallas cuadriláteras están ajustados paralelamente a una dirección axial de dicho tubo hueco (1); y se satisfacen las relaciones 2 mm

Abstract:
The present invention relates to a porous, selectively adsorptive material selected from an Al, Ti or Zr type oxide and having a mean pore diameter of not greater than 5 nm, and a porous, selectively adsorptive material comprising an Si oxide and having a mean pore diameter of 1 to 5 nm. The material of the present invention has particularly excellent selective adsorptivity of Nox in an alumina type material.
Abstract:
Un método de procesamiento de agua, que comprende las etapas de: separar agua que contiene boro usando al menos dos módulos de membrana de ósmosis inversa para proporcionar un agua permeada y procesar al menos una parte del agua permeada obtenida en un primer módulo de membrana de ósmosis inversa con un segundo módulo de membrana de ósmosis inversa; en el que al menos una parte de un agua concentrada obtenida en el segundo módulo de membrana de ósmosis inversa se somete a eliminación de boro usando un adsorbente, en el que el agua sometida a la eliminación de boro se mezcla con el agua no sometida a la eliminación de boro del agua permeada del primer o el segundo módulo de membrana de ósmosis inversa para proporcionar un agua mixta.
