PROBLEM TO BE SOLVED: To provide a water treatment apparatus capable, by contacting a vapor-liquid mixed liquid with the entire surface of a membrane module more homogeneously than ever, of preventing functional deteriorations of the membrane module.SOLUTION: Configured on an aerator 1 are: a gas supply pipe 21 for supplying a gas from a gas supply apparatus; main pipings 2 connected to the gas supply pipe 21 in a state where at least portions thereof are being positioned underneath a membrane module unit 10; and aerating pipes 3 supported by the respective main pipings 2 in linked states, extending horizontally underneath the membrane module unit 10, and possessing aerating holes 8. Multiple main pipings 2 branch from the gas supply pipe 21, whereas aerating pipes 3 are supported on the respective branched main pipings 2 in linked states. |
