PROBLEM TO BE SOLVED: To provide a water treatment system capable of uniformly flowing the raw water of a gas-liquid mixed flow to a plurality of tubular membranes even at a low flow velocity while retaining a bubble charging ratio high in a membrane cleaning effect.SOLUTION: Provided is a water treatment system comprising: a membrane module having a plurality of tubular membranes and filtering raw water; a raw water feed part of feeding the raw water from a water source of the raw water to the membrane module; a gas feed part of feeding a gas to the raw water and making the raw water fed to the membrane module into a gas-liquid mixed flow; and a surface tension emollient feed part of adding the surface tension emollient to the raw water. |
