The present invention discloses a detection and analysis apparatus, comprising a photo sensing device, comprising a plurality of sensing elements linearly arranged to form a first array, for detecting a signal of the thickness change of the cake at a linear position of the filter medium; a driving device, for driving the photo sensing device to move relatively parallel to the filter medium on the top of the cake so that the photo sensing device detects the thickness change of the cake on at least one local plane of the filter medium; and a data processing device, coupling to the photo sensing device, for continuously processing and analyzing the signal detected by the photo sensing device to thereby in-situ estimate the thickness change of the cake on the at least one local plane of the filter medium during the filtration process.

Detection and analysis apparatus for membrane filtration process

The present invention discloses a feed spacer, comprising a first layer and a second layer, for spiral-wound membrane module. The first layer consists of a plurality of first filaments, which are substantially in parallel to one another. Furthermore, the second layer also consists of a plurality of second filaments, which are substantially in parallel to one another. Moreover, the first layer is attached to the second layer, and the first filaments are disposed at an angle to the second filaments. Both the first layer and the second layer bend to the center of the spiral-wound. Additionally, the distance from the inside of the first layer to the center is bigger than that from the inside of the second layer to the center, and the diameter of the first filament is smaller than that of the second filament.
