Abstract
A transverse-mounted membrane filtration apparatus includes an air diffuser device including a shelf-shaped member and a gas-feeding unit, the shelf-shaped member including a plurality of shelf boards being arranged in a flow path segment at an immediate upstream of an end surface of a membrane element with a predetermined distance from the end surface of the membrane element and covering an entire flow path of the membrane element along a vertical direction, the gas-feeding unit feeding a gas to the raw water for washing the membrane element through a gas-feeding port provided at a bottom portion of a flow path of the shelf-shaped member. Herein a shelf board at a lowermost position of the shelf-shaped member is inclined toward a side of the end surface of the membrane element in a vertically upper direction.
