ABSTRACT:
A liquid flow distribution screen is disclosed in which two sets of spaced apart strands are oriented at an angle to each other to form a mesh screen. A portion of the screen is composed of areas in which the two sets of strands are more or less of the same thickness and the remaining portion composed of strands in which one of the sets is of greater thickness than the other, resulting in the creation of liquid flow channels between and among the channels. Using this concept, any desired flow pattern may be achieved when the screen is placed between two surface barriers. The device is particularly suited as a membrane support and spacer in electrodialysis or electrochemical apparatus.
