Abstract
Printed spacer membrane elements offer the unique advantage of applying any pattern on the membrane surface to act as the feed spacer material. This is in contrast to conventional feed spacer mesh material that is uniform in thickness and density throughout the mesh. More open feed spaces can be utilized but may also result in higher stress concentration, and where the spacer material comes in contact with the opposing membrane leaf. This patent presents concepts for reducing the damage on membrane leaves by increasing the concentration of the print pattern near the center tube where the stress concentration on the membrane leaves is greatest, orienting the membrane sheets prior to rolling to minimize damage from slippage during rolling, moving the fold away from the first features to minimize leaks at the insertion point.
