FLAT MEMBRANE ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a flat membrane element capable of uniformly collecting water on the entire membrane surface by equalizing pressure loss at a counter vertical water collecting groove side end part regardless of a distance from a water collecting discharge port. SOLUTION: In the flat membrane element E configured by forming a vertical water collecting groove 2 along the vertical direction on at least one side end of a flat membrane element support 1 and spreading a filtration membrane 3 on the entire surface, horizontal grooves 5 in the horizontal direction are formed on the flat membrane element support 1 so as to equalize the pressure loss at the counter vertical water collecting groove side end part of the flat membrane element support 1 regardless of a distance from the water collecting discharge port 4.
