摘要:
The invention concerns a device for isolation of material, such as medical substances, present in dissolved state in human or animal urine. Said device comprises a urine receiving unit (3), a vaporization chamber (6) being in fluid communication with said urine receiving unit, a vapor evacuation unit being in fluid/vapor communication with said vaporization chamber, a protective structure (21) being vapor permeable and operative as a demister so as to prevent mist-building liquid droplets from passing through the vapor evacuation unit, and a waste container (9) for receiving waste from the vaporization chamber. The waste container is in fluid communication with the vaporization chamber. The invention further regards a method for isolation of material, such as medical substances, present in dissolved state in human or animal urine.

Fusion proteins containing a targeting sequence, an exosporium protein, or an exosporium protein fragment that targets the fusion protein to the exosporium of a Bacillus cereus family member are provided. Recombinant Bacillus cereus family members expressing such fusion proteins are also provided. Genetically inactivated Bacillus cereus family members and recombinant Bacillus cereus family members that overexpress exosporium proteins are also provided. Seeds coated with the recombinant Bacillus cereus family members and methods for using the recombinant Bacillus cereus family members (e.g., for stimulating plant growth) are also provided. Various modifiations of the recombinant Bacillus cereus family members that express the fusion proteins are further provided. Fusion proteins comprising a spore coat protein and a protein or peptide of interest, recombinant bacteria that express such fusion proteins, seeds coated with such recombinant bacteria, and methods for using such recombinant bacteria (e.g., for stimulating plant growth) are also provided.

An ozone generator (1) is presented comprising a body (2), a first electrode (4), a second electrode (6), an elongate channel within the body extending between the first and second electrodes, an inlet (10) and an outlet (12); the elongate channel being in fluid communication with the inlet and the outlet; the elongate channel isolated from each of the first and second electrodes by a respective dielectric layer (22, 24), whereby an electric field can be generated across the elongate channel between the first and second electrodes. The presented ozone generator allows small quantities of ozone to be produced for use in small scale water treatment. In addition, a method of producing ozone is presented using an ozone generator according to the invention.

Poly (sulfoaminoanthraquinone) polymer compositions and methods of making these compositions are disclosed herein. The polymer compositions can, for example, be used for removing metal ions from a sample.
摘要:
A waste water compact disinfection plant for hospital wards comprises, in combination, at least a mechanical treatment station (2) and a chemical disinfection station (3). It may also have a mechanical pre-treatment station (4), in which the solid materials present in the waste water are ground while wet. The mechanical treatment station (2) comprises an apparatus (21) for separating and dehydrating the solids present in the waste water and the chemical disinfection station (3) comprises a disinfection tank (31) with a mixer (32) and at least one disinfectant feed reservoir (33), as well as means (34) for delivering the disinfectant located between the reservoir (33) and the disinfection tank (31).
摘要:
The present invention is a method for controlling ( e.g. inhibiting) the growth of microorganisms or killing microorganisms in an aqueous solution, such as that found in a water treatment facility or papermaking facility. The method includes adding an effective amount of (a) a free halogen-generating biocide, (b) a halogen stabilizer, and (c) a quaternary ammonium compound, a biocidal amine or salt thereof, or mixture thereof to the aqueous solution. The aqueous solution may be water in a recreational facility, an industrial cooling system, a water treatment facility or a water slurry, such as a circulating water slurry, in a papermaking facility. The mixture of the present invention is useful as a slimicide. The quaternary ammonium biocide and/or biocidal amine increase the efficacy of the free halogen-generating biocidal system.
摘要:
Method and apparatus for treating biological suspensions. A treatment agent is added to the biological suspension to form a mixture. The mixture is mechanically treated in a disintegrator 18 to homogenise and finely divide the mixture. The mixture is subsequently pressurised.
摘要:
A process and apparatus (10) for teatment of sludge is provided. The process includes providing sludge (34) in a substantially liquid form and an alkaline additive (29) to a preferably substantially closed reactor vessel (20), mixing the sludge and additive to ensure that the pH is greater than about 12, maintaining the pH for a period of time, optionally supplying supplemental heat through heating elements (40) to the sludge mixture (34) in the reactor vessel to achieve an elevated temperature for a period of time, maintaining the sludge mixture (34) in a substantially fluid liquid condition, and discharging the sludge and additive mixture (34) from the reactor vessel (20) in a substantially liquid form such that it lends itself to be handled by gravity flow.
