Abstract: An article comprises a tube having peripheral areas, including an upper section, a lower section, an inner section, and an outer section, the tube further comprising a tube wall having an outer layer of a semipermeable membrane that is permeable to vapors but impermeable to liquids, and the tube further comprising at least one inlet port integrated into the tube wall to permit the flow of an activated or activatable foamable composition into the tube interior, wherein the tube further has a plurality of holes that penetrate through the outer layer of the tube to allow expanding foam to both fill the interior of the tube and exit the tube and fill a space exterior to the tube.

Abstract: A method for membrane filtration of water comprising alternating in-line additions of coagulant and adsorbent to the water upstream of the membrane, wherein each addition time is in a range from 10 seconds to one hour.

Abstract: This invention is directed to a non-rigid composite sheet comprising in order (i) a first component having an areal weight of from 88 to 678 gsm comprising a first fabric of filamentary yarns having a tenacity of at least 11 g/dtex and a UV and weather impervious first polymeric layer. (ii) a second component having an areal weight of from 120 to 430 gsm comprising a flame resistant paper and (iii) a third component having an areal weight of from 88 to 678 gsm comprising a second fabric of filamentary yarns having a tenacity of at least 11 g/dtex and an impact and scratch resistant second polymeric layer, the second fabric of the third component being adjacent to the paper of the second component.
