Water treating apparatus

A water treating apparatus comprising:

• a housing for receiving water to be treated fed thereto;
• a membrane module unit for applying filtration treatment to the water to be treated in the housing and extracting treated water, the membrane module unit being contained in the housing such that the membrane module unit can be pulled out from the housing;
• and
• a housing holder for holding the housing tiltably between a position where a longitudinal direction of the membrane module unit is substantially vertical and a position where the longitudinal direction of the membrane module unit is substantially horizontal,
• wherein the membrane module unit comprises:
• a membrane module;
• a holder for holding the membrane module;
• abutting members provided at the holder, the abutting members abutting on an inner wall surface of the housing and being movable on the inner wall surface,
• wherein the holder comprises:
• a center pipe extending along the longitudinal direction of the membrane module and positioned substantially at a center, the center pipe spraying high-pressure water on the membrane module;
• a membrane module holder supported by the center pipe, the membrane module holder holding the membrane module in a position around the center pipe;
• and
• abutting member holders supported by the center pipe, the abutting member holders holding the abutting members, and
• wherein the abutting member holders are disposed at one end and the other end of the center pipe in the longitudinal direction, and one of the abutting member holders at the one end and one of the abutting member holders at the other end are coupled by a gas supply pipe extending in the longitudinal direction of the membrane module, the gas supply pipe blowing gas toward the membrane module.
