  • Patent number: 11084198
    Abstract: In at least one embodiment, a membrane filtration element is provided. The element may include at least one feed spacer including a first set of parallel strands extending in a first direction and including a plurality of first strands having a first thickness and a plurality of second strands having a second thickness that is smaller than the first thickness. A second set of parallel strands may extend in a second direction that is transverse to the first direction. The second set of parallel strands may include a plurality of third strands having a third thickness and a plurality of fourth strands having a fourth thickness that is smaller than the third thickness. In one embodiment, the first and second sets of strands include alternating thick and thin strands, which reduce pressure drop in membrane filtration systems.

  • Patent number: 10850452
    Abstract: A method and machine for sealing at least one cut edge of a foam board is disclosed. The foam board has a top surface, a bottom surface and at least one cut edge extending between the top surface and the bottom surface. The cut edge is passed over a heated roller to soften the edge and then passed over a second roller having a temperature that is lower than the temperature of the first roller which seals the edge. The cut edge may be milled to square the edge relative to the top and bottom of the board before the cut edge is passed over the heated roller. Additional pairs of rollers may be provided to seal the top surface and the bottom surface of the foam board.
