Abstract:
Provided is a method for producing a chlorogenic acids composition having a reduced caffeine content and good taste and favor, capable of efficiently recovering high purity of chlorogenic acids from a chlorogenic acids-containing composition. The method for producing a purified chlorogenic acids composition comprises a step A of bringing a chlorogenic acids-containing composition into contact with a cation exchange resin; a step B of bringing the liquid obtained in the step A into contact with an anion exchange resin; and a step C of bringing an eluent into contact with the anion exchange resin after the step B.
Abstract:
A method and apparatus for extracting CO2 from air comprising an anion exchange material formed in a matrix exposed to a flow of the air, and for delivering that extracted CO2 to controlled environments. The present invention contemplates the extraction of CO2 from air using conventional extraction methods or by using one of the extraction methods disclosed; e.g., humidity swing or electro dialysis. The present invention also provides delivery of the CO2 to greenhouses where increased levels of CO2 will improve conditions for growth. Alternatively, the CO2 is fed to an algae culture.
Abstract:
A process for removing suspended particles and at least one ionic species from a feed water stream to produce a product water stream, the process includes the steps of forming agglomerates of the suspended particles in the feed water stream; passing the feed water stream containing agglomerated particles through a bed of particulate sorbent material so as to sorb the ionic species from the feed water onto the sorbent to provide a loaded sorbent and filter the agglomerated particles from the feed water using the bed of particulate sorbent material as a filtration medium to load the bed with the agglomerated particles, and thereby produce the product water stream; removing the filtered particles and the ionic species from the filtration medium; and re-using the regenerated sorbent in step b).
Abstract:
A process for reducing thermally induced discoloration of fluoropolymer resin produced by polymerizing fluoromonomer in an aqueous dispersion medium to form aqueous fluoropolymer dispersion and isolating the fluoropolymer from the aqueous medium to obtain fluoropolymer resin. The process comprises: contacting the aqueous fluoropolymer dispersion with sorbent.
Abstract:
A filtration media is disclosed comprising functionalized particles distributed throughout a sintered porous matrix, the sintered porous matrix derived from a combination of components comprising first ultra-high molecular weight polyethylene initially comprising a plurality of non-porous particles having a first shape that is substantially spherical; second ultra-high molecular weight polyethylene initially comprising a plurality of non-spherical perforated particles having a second shape that is convoluted; and third ultra-high molecular weight polyethylene initially comprising a plurality of non-spherical perforated particles having a third shape that is convoluted, wherein the functionalized particles comprise a range from about 20% by weight to about 90% by weight of the sintered porous matrix.
Abstract:
The invention provides waste water treatment processes utilizing an ion exchange resin to remove sulphate anions, while adjusting the pH of the ion exchange loading solution with carbon dioxide gas. The effect of the resin loading reactions is that dissolved sulphate is replaced with sequestered carbon dioxide gas, in the form of dissolved bicarbonate, in the treated water and the cations are not removed from the solution.

Abstract:
A method for recovering and/or utilizing potassium from waste waters for a plurality of applications. As algae and plants are able to survive and flourish in environments with high salt concentrations, waste waters containing potassium can be applied as fertilizers to the growth of microbes, algae and plants. The microbes, plants, and algae are able to absorb the necessary nutrients, such as nitrogen and potassium, from the waste waters. After depletion of the potassium content from the waste water, that waste water can then be treated to separate other contaminants. In another aspect of the present invention, the potassium content may be first separated from the waste water to be applied for growth of microbes, plants, and algae and again used for regeneration of cation resins in specific potassium forms. The remaining contaminants that are separated through treatment of the waste water can be utilized for different productions.
