Abstract

Se proporciona una membrana de separación para el pretratamiento de desalación de agua de mar capaz de suministrar una cantidad adecuada de agua natural a una membrana de OI de manera constante con un flujo que se mantiene elevado y sin aumentar la presión, al tiempo que se retiran PET con una tasa de retirada elevada. También se proporciona un dispositivo de pretratamiento de desalación de agua de mar y un método de desalación de agua de mar. La membrana de separación para el pretratamiento de desalación de agua de mar es una membrana de separación para el pretratamiento de desalación de agua de mar usada en el pretratamiento para la desalación de agua de mar con una membrana de ósmosis inversa, donde#un flujo estándar A es de 2 m/d o más, que se define como valor máximo de un flujo que puede cumplir P2<=1,5x1, donde P1 representa una presión diferencial media de intermembrana para los 30 minutos iniciales y P2 representa una presión diferencial media de intermembrana para los 30 minutos posteriores a un lapso de 120 minutos, cuando se lleva a cabo la filtración a un flujo fijo, y#una tasa B de retirada de sacáridos o tasa C de retirada de carbono granular expresadas por medio de las ecuaciones siguientes es de 0,3, y de manera deseable de 0,5 o más;#Tasa B de retirada de sacáridos = (1 - cantidad de sacárido en el agua filtrada/cantidad de sacárido en el agua natural)#Tasa C de retirada de carbono granular = (1 - COP en el agua filtrada / COP en el agua natural)#donde COP se refiere a una cantidad de carbono orgánico en forma de partículas (una diferencia entre una cantidad de carbono orgánico total y una cantidad de carbono orgánico disuelto).A separation membrane is provided for seawater desalination pretreatment capable of supplying an adequate amount of natural water to an RO membrane constantly with a flow that remains high and without increasing the pressure, while withdrawing PET with a high withdrawal rate. A seawater desalination pretreatment device and a seawater desalination method are also provided. The separation membrane for seawater desalination pretreatment is a separation membrane for seawater desalination pretreatment used in the pretreatment for seawater desalination with a reverse osmosis membrane, where # a standard flow A is 2 m / c or more, which is defined as the maximum value of a flow that can meet P2 <= 1.5x1, where P1 represents an average intermembrane differential pressure for the initial 30 minutes and P2 represents an average differential pressure of intermembrane for the 30 minutes after a period of 120 minutes, when filtration is carried out at a fixed flow, and # a saccharide removal rate B or granular carbon removal rate C expressed by the following equations is 0.3, and desirably 0.5 or more; # Saccharide removal rate B = (1 - amount of saccharide in filtered water / amount of saccharide in natural water) # Carbon removal rate C granular = (1 - COP in filtered water / COP in natural water) # where COP refers to an amount of particulate organic carbon (a difference between a total organic carbon amount and a dissolved organic carbon amount).
