Abstract:
The present invention discloses an adsorbent composition of chitosan reinforced mixed oxide granular nanocomposite for water-related applications, specifically for water purification. The granular nanocomposite comprises active ingredients homogenized in the aggregated network of chitosan templated aluminum oxyhydroxide/2-line iron oxyhydroxide composite. The composition is versatile as any metal or non-metal ion (including transition metals and/or rare earth metals) can be used. The composition itself can be a water purifier, such as an adsorbent for fluoride and arsenic removal from water with excessively high fluoride and arsenic adsorption capacity.
Abstract:
Sachet de dépollution (1) pour piéger des COV et notamment le formaldéhyde formé d'une pièce avant et d'une pièce arrière (1a, 1b) en une matière perméable à l'air, assemblées en formant un bord le long d'une partie du contour (121) pour réaliser un compartiment plat, en laissant une ouverture (13) au niveau du contour et recevant une charge de matière de dépollution à l'état de granulés dans le compartiment plat qui est ensuite fermé après remplissage avec la charge.
Abstract:
The present invention relates to a fully moisture-tight multilayer material, which is also able to absorb, retain and not release the absorbed moisture or free water into the formulations containing pharmacological active substances and/or instable components with biological activity and/or effervescent and/or easily perishable formulations; said material being useful for preparing bags, envelopes and sachets for packaging food, dietary and cosmetic products, medical devices and medicinal products. The multilayer material of the present invention is a multilayer material that is useful for preparing containers in the form of bags, envelopes, sachets and sticks coming into direct contact with the formulations of the food, dietary and cosmetic products as well as of the medical devices and medicinal products in the form of e.g. lactic bacteria and/or bifidobacteria in powders or granules, either dried or freeze-dried.
Abstract:
Self filling flood-protection bag consists of two enclosed chambers (1), that are interconnected by terminal yoke (2) in form of letter "T" and that are made of polyester fabric with high water absorbing capacity. Chambers (1) are filled up with granular or jelly mixture of water superabsorbents (3) based on cross-linked polyacrylate (SAP). Terminal yoke (2) contains two handling metal eyelets (4).
Abstract:
A process for manufacturing a floatable oil absorbing device comprises: cutting a non-woven polymeric master web (100) into pieces; collecting a predetermined amount of the pieces; placing the predetermined amount of the pieces onto a bottom sheet of an envelope material; placing a top sheet of an envelope material on the predetermined amount of the pieces and the bottom sheet; and heat-sealing or welding peripheral regions of the top and bottom sheets together to form the device.
Abstract:
A device for the placement inside a container (20) comprises a body (12) forming at least two separate compartments (30, 32) for active materials (40, 42), each compartment (20, 32) having a predetermined inner volume for receiving an active material (40, 42) and at least a surface portion permeable for a specific gaseous and/or liquid substance to become trapped or released by the active material (40, 42) inside the respective compartment (30, 32).
Abstract:
