    摘要: The present invention relates to an aqueous ozone floor disinfection system. A floor cleaning machine traverses a floor surface entering a pre-hygienic zone prior to cleaning, cleaning within a midst-hygienic zone for a cleaning period, and moving away from the midst-hygienic zone creating a post-hygienic zone. An aqueous ozone generator receives water and generates an ozonated concentrate liquid. A post-hygienic mixer ratiometrically blends the ozonated concentrate liquid and water to form a post-hygienic ozone disinfection solution having a predetermined post-hygienic ozone treatment concentration. A post-hygienic nozzle spray of the post-hygienic ozone disinfection solution onto the post-hygienic zone portion of the floor surface for at least a post-hygienic treatment time absent agitation or removal by the floor cleaning machine improving disinfection of the floor surface. The service life of the aqueous ozone generator can be tracked and the disinfected floor surface can be GPS geofenced.

    摘要: A decontamination assembly (1) for pharmaceutical applications, comprising an isolator (2) having a manipulator chamber (3) and a plenum chamber (4) which is disposed above the manipulator chamber (3) and which can be supplied with an air flow (9) via at least one circulation fan (7) disposed in a circulating-air generation chamber, a membrane (5) for generating a laminar air flow (11) in the manipulator chamber (3) during a working operating state being disposed between the plenum chamber (4) and the manipulator chamber (3), the manipulator chamber (3) being connected to the circulating-air generation chamber (6) in an air-conducting manner via a return-air channel (12), further comprising ultrafine distributing means (19), for producing a decontaminant/air mixture based on a liquid decontaminant stock, a stock of H2O2, the ultrafine distributing means (19) being connected to the plenum chamber (4) via at least one plenum supply line (25) leading into the plenum chamber (4) so as to directly supply the plenum chamber (4) with the decontaminant/air mixture when in a decontamination operating state, wherein the ultrafine distributing means (19) are connected directly to the manipulator chamber (3) via at least one manipulator supply line (27) so as to directly supply the manipulator chamber (3) with the decontaminant/air mixture when in the decontamination operating state.

    摘要: Provided are mobile decontamination units and methods of using such units for decontaminating various areas, such as aircraft cabins. A mobile decontamination unit comprises at least one aerosol dispersing nozzle and at least one aerosol directing fan. The nozzle disperses disinfectant in the aerosol form, while the fan directed this aerosol to surfaces being decontaminated. Aerosol dispersing parameters, such the nozzle and fan orientations, dispersing rate, fan speed, and the like, are determined based on area characteristics. Specifically, orientations of different surfaces, temperature, humidity and/or other like characteristics may be considered. Some characteristics may be obtained by the mobile decontamination unit after its deployment in the area, such as using its sensors. Other characteristics, such as area layout, may be preloaded to the mobile decontamination unit prior to its deployment. The dispersing parameters are determined to ensure through decontamination of the surfaces in the area.
