PROBLEM TO BE SOLVED: To prevent generation of aggregates, defective dissolution into water and hydrolysis or the like, in an agent for improving a blocking rate of RO membrane containing two or more organic compounds whose molecular weights are different and to effectively use the agent for improving blocking rate in a process of improving blocking rate of RO membrane.SOLUTION: An agent for improving a blocking rate of a reverse osmosis membrane includes: organic compounds having at least an amino group whose molecular weight is not less than 60 and less than 500 as two or more organic compounds whose molecular weight are different; and tannic acid, wherein the organic compounds having the amino group and the tannic acid are stored as two powdery medical agents which are different from each other. |
