Aqueous compositions formed from combining water, and at least one solute such as sodium bicarbonate, acetylsalicylic acid or mixtures thereof, are used to introduce and maintain relatively high levels of carbon dioxide in the atmosphere of selected environments. The aqueous compositions benefit live plants and prolong the shelf life of various perishable foods and products, including vegetables, fruits, meats, fish, seafood, dairy products, and dry goods and ingredients. The aqueous compositions are applied directly by bathing or showering a perishable product in the aqueous compositions, or indirectly with absorption devices that carry the aqueous compositions, and which are placed in close proximity to a perishable product. An aqueous composition can be applied to or formed directly on an absorption device. An absorption device can also be recharged by reapplying or reforming the aqueous composition to the absorption device as needed.

A pre-treatment method for cleaning and maintaining reverse osmosis membrane filters by injecting sulfurous acid into waters with suspended solids in a liquid fraction to be filtered to form sulfurous acid (H₂SO₃) to acid leach heavy metals into the liquid fraction, reduce alkalinity and mineral scaling, add sufficient SO₂ as a biocide to attack bacteria and other micro organisms to prevent membrane fouling, reduce iron to prevent iron deposit build-up, scavenge and remove dissolved oxygen prior to filtration to prevent membrane oxidation, and then sequentially filtering the acidified water through membrane filters to create a metal free permeate and a brine retentate, which can be pH adjusted to remove the heavy metals as metal hydroxide precipitates.

It is intended to provide a process for producing a packaged drink whereby filling can be performed at room temperature without resorting to using a chemical or sterile water, the favorable taste and flavor of the content can be maintained while relieving the thermal degradation thereof, it becomes unnecessary to employ a heat-resistant container or to thermally sterilize or cool after sealing, and thus both of the equipment cost and the running cost can be largely reduced. After thermally sterilizing the content to give a definite sterilization value, it is quickly cooled to room temperature and then stored in a storage tank that has been preliminarily sterilized under such conditions as being equal to or exceeding the thermal sterilization conditions for the contents. While maintaining the storage tank under positive pressure with the use of a sterile gas, the content is fed into a filling machine that has been preliminarily sterilized under such conditions as being equal to or exceeding the thermal sterilization conditions for the contents. Thus, the liquid-feeding system ranging from the storage tank to the filling machine is made a closed liquid-feeding pathway free from the invasion of air from the outside. The drink is filled into a container having been sterilized with hot water in an environment-controlled space isolated from the outside wherein the surroundings have been thermally sterilized and washed with hot water at 65° C. to 100° C.

A wipe that contains a fibrous web on which is coated an antimicrobial composition is provided. The composition includes a botanical oil derived from a plant (e.g., thymol, carvacrol, etc.). Because the botanical oil is volatile and tends to evaporate and lose efficacy during storage and prior to use, a protein is also employed in the composition to enhance long term stability of the oil and, in turn, its antimicrobial efficacy. The protein is “film-forming” in the sense that it tends to form a substantially continuous film when coated onto a surface of the fibrous web. Because such proteins are typically stiff and brittle in nature, a continuous film would restrict the ability of the fibers to move and bend, thereby reducing web flexibility and drape. Thus, it is typically desired that the antimicrobial composition form a discontinuous coating on the fibrous web. In this regard, the present inventors have surprisingly discovered that the addition of an organopolysiloxane can help achieve such a discontinuous coating without adversely impacting the ability of the protein to stabilize the botanical oil. The organopolysiloxane may also enhance the softness and overall handfeel of the wipe.

In the present disclosure, silver ions, copper ions, quaternary ammonium compounds and cationic drugs such as sulphanilamide, chlorhexidine acetate, etc., used as antibacterial agents are incorporated into fibers, filaments and films through nanoclays. The nanoclays serve as a carrier for the antimicrobial agents and are incorporated into the fiber-forming polymer. In one embodiment, the biocidal metals and organic compounds are incorporated into the clay structure via an ion exchange reaction. Nylon nanocomposite filaments and films based on copper and quaternary ammonium ion modified clays provide 100% antibacterial activity against Gram positive Staphylococcus aureus and Gram negative Escherichia coli bacteria at an optimum clay loading of 0.75% (by weight), and the activity is retained up to 50 washes. The resulting filaments show enhanced mechanical properties such as tensile strength and modulus, and find application in areas of medical textiles like sutures, wound dressings and health & hygiene textiles. In addition, they can be integrated into protective clothing, body garments, sportswear and upholstery.
