Abstract
A membrane element having a filtration main body, a header (a water collection portion) that collects treated water from an end portion of the filtration main body and a treated water lead-out portion that leads out the treated water is used. The treated water lead-out portion is connected to a tubular peripheral wall of a water collection pipe that collects treated water solid-liquid-separated by the membrane element, and communicates with an inside of the tubular peripheral wall. The tubular peripheral wall has a thick portion that is thicker in a horizontal direction at an upper-side peripheral wall portion located at an upper side (or at a lower-side peripheral wall portion located at a lower side) in the radial direction of the tubular peripheral wall, and a connecting hole that penetrates the thick portion.
