  • Publication number: 20240066073
    Abstract: Described are compositions and methods relating to layered granules comprising a core surrounded by a coating layer containing bioactive agents distributed within a protectant matrix, wherein the protectant matrix includes at least one polyhydroxy compound and at least one phosphate compound. The core and the protectant matrix are water soluble and fast-dissolving.

  • Patent number: 9180393
    Abstract: A liquid filter with a composite medium that has a nanoweb adjacent to and optionally bonded to a microporous membrane. The membrane is characterized by an LRV value of 3.7 at a rated particle size, and the nanoweb has a fractional filtration efficiency of greater than 0.1 at the rated particle size of the membrane. The nanoweb also has a thickness efficiency ratio of greater than 0.0002 at that efficiency. The nanoweb acts to provide depth filtration to the membrane, prefilters particles and extends the lifetime of the membrane.

  • Patent number: 8689985
    Abstract: Filtration media including at least one layer of nanofibers having average diameters less than 1000 nanometers with optional scrim layer(s) are disclosed for filtering particulate matter in liquid. The media achieve flow rates of at least 0.055 L/min/cm2 at relatively high levels of solidity. The media have also advantageously been found to have non-diminishing flow rates as differential pressures increase between 2 psi (14 kPa) and 15 psi (100 kPa).

  • Patent number: 8038013
    Abstract: A liquid filter with a composite medium that has a nanoweb adjacent to and optionally bonded to a microporous membrane. The membrane is characterized by an LRV value of 3.7 at a rated particle size, and the nanoweb has a fractional filtration efficiency of greater than 0.95 at the rated particle size of the membrane. The nanoweb also has a thickness efficiency ratio of greater than 0.01 at that efficiency. The nanoweb acts to provide depth filtration to the membrane, prefilters particles and extends the lifetime of the membrane.

  • Publication number: 20110033608
    Abstract: A process for coating water-swellable hydrogel microspheres with various coating materials is described. The coating process described herein is a fluidized bed process, which utilizes inert, cofluidization particles to aid the fluidization of the microspheres. The use of the cofluidization particles increases the efficiency of the coating process and improves the quality of the coating obtained.

  • Patent number: 7441667
    Abstract: An improved casting substrate is provided for use in a composite membrane for use as a fluid filtration medium. The composite membrane has good adhesion between the casting substrate and the microporous membrane while maintaining high permeability. The casting substrate comprises a single spunbond layer or a multiple spunbond layers formed of thermoplastic fibers, optionally comprising at least one meltblown layer. The casting substrate allows the membrane casting solution to penetrate the casting substrate uniformly to a controlled depth without penetrating through the entire thickness of the substrate. The casting substrate has good uniformity of mean pore size, basis weight, thickness and surface roughness.
