Reverse osmosis membrane rejection rate improving method, rejection rate improving treatment agent, and reverse osmosis membrane |
| abstract |
The present invention provides a RO membrane rejection rate improving method in which the stability of removal performance (rejection rate) and flux stability (sustainability of contamination resistance) are further improved. In the method for improving the RO membrane rejection rate, the method further comprising the step of passing an aqueous solution containing polyphenol through the RO membrane, one or two selected from the group consisting of modified polyvinyl alcohol, high molecular polysaccharides and polyamino acids. An RO membrane rejection rate improving method comprising a step of passing an aqueous solution containing seeds or more through the RO membrane. Preferably, the method further includes a step of passing an organic compound having an amino group having a molecular weight of 1000 or less through the RO membrane. [Selection] Figure 1 |
