摘要:
PROBLEM TO BE SOLVED: To provide a separation membrane which is excellent in a salt rejection rate even while having high strength, high porosity and a high hydrophilization degree, and to provide a manufacturing method of the separation membrane and a water treatment apparatus including the separation membrane.SOLUTION: The separation membrane including a support layer and a polymer matrix layer is provided. The support layer contains a polymer including a structure unit indicated in general formula 1, and the polymer matrix layer is a semipermeable membrane and has a rejection rate for a separation target substance higher than that of the support layer.
