摘要：
A hydrophilizing agent for a hydrophobic porous membrane, wherein the agent contains a surfactant, and the surfactant has a frothability such that the bubble height immediately after frothing, as measured according to the Ross-Miles method (JIS K 3362), using a 0.1 wt % aqueous solution of the surfactant at 25° C., is 40 mm or less, and preferably has a frothability such that the bubble height five minutes after frothing is 20 mm or less; a method for hydrophilizing a hydrophobic porous membrane using this hydrophilizing agent; and a method for testing and hydrophilizing a membrane module using this hydrophilizing agent.
