A disinfection system for treating water. In a specific example, the system treats water prior to its upload to an aircraft or other passenger transportation vehicle. One or more replaceable filters are positioned within a filter chamber housing in order to expose water flowing through the system to filtration treatment.

The invention relates to a new biological fluidized bed process with high concentration powder carriers used for the treatment of municipal wastewater, which is a fluidized bed system based on the principle of sewage biochemical treatment, by adding a compound powder carrier to the biochemical tank, and forming a high concentration mixture after mixing and microbial attachment; the sludge mixture after the reaction is concentrated and separated, and then enters the compound powder carrier cyclone separation and recovery system, which can separate most of the compound powder carrier from the discharged excess sludge, and then return to the biochemical tank for recycling. The highly integrated municipal wastewater treatment process proposed in the invention has high treatment efficiency, small occupation area, low operation energy consumption, and can realize the doubling of sewage treatment capacity and the improvement of effluent water quality without adding additional occupancy.

A system for meat processing may include: a conveyor configured to transport animal carcasses or portions of meat through a meat processing facility; and a spray system configured to spray each of the animal carcasses or portions of meat with aqueous ozone when each of the animal carcasses or portions of meat is transported to the spray system by the conveyor. The system may further include a second spray system configured to spray each of the animal carcasses or portions of meat with lactic acid or citric acid when each of the animal carcasses or portions of meat is transported to the second spray system by the conveyor.

The present invention relates to a UV lamp having an axial dimension normal to a cross-section having a cross-sectional area with a ratio of the axial dimension to the cross-sectional area in the range of 0.1 cm/cm.sup.2 to 1000 cm/cm.sup.2. The UV lamp includes a first axial conductor separated from a second axial conductor by an electrically insulating material and a light emitting diode (LED) capable of providing light at a wavelength in the range of 100 nm to 400 nm, which LED is mounted to emit light from an outer surface. The invention also relates to a method of sterilising a surface using the UV lamp.

The present disclosure provides an apparatus comprising a primary treatment system configured to remove solids from an untreated fluid to generate a primary treated fluid. The apparatus further comprises an oxidation treatment system including an inlet configured to receive the primary treated fluid, an ozone inlet configured to receive ozone from an ozone generator, and an outlet configured to dispense secondary treated fluid. The apparatus may further comprise a controller in electrical communication with the ozone generator. The controller is programmed to regulate the flow of ozone through the oxidation treatment system such that an effective amount of ozone contacts the primary treated fluid to generate the secondary treated fluid. In some embodiments, the secondary treated fluid discharging from the oxidation treatment system has a chemical oxygen demand (COD) removal level of greater than 85%.

Methods, systems, and apparatuses for temporarily increasing, on demand, the relative humidity of an area located proximate to a user in environments having lower than ambient relative humidity are provided by integrating a personal humidification circuit into a water delivery circuit to provide a diverted flow of water, and provide a flow of water vapor to a user, and returning the relative humidity-enhanced environment to a predetermined relative humidity by purging the environment.

The present disclosure concerns module for disinfecting water by UV radiation, for example source or miming water to be disinfected for the purpose of serving as drinking water. In particular, the present disclosure provides a UV-LED radiation-based modules for disinfecting water before consumption, the modules include at least one removable lens for prolonging the service life of the module.

The present invention relates to a family of very stable aqueous hypochlorite products and methods for reducing the self reactivity of Ca(OCl).sub.2.

The invention relates to a method and a system for purification of water in a water purification system. The water purification system comprises first and second mixing reactors, first and second flotation reactors and first and second filters all serially and fluidly connected in a flow direction of the water as well as an electrolyzer. During the process, electrochemical synthesis of the reagents takes place in the cathode and anode chambers of the electrolyzer, respectively. Moreover, the electrochemically synthesized catholyte and anolyte are dosed into the water kept in the first and second mixing reactors, respectively. Then the mixtures in the first and second mixing reactors are mixed. After that, the flow of the treated water leaving the mixing reactors is passed through the first and second flotation reactors and afterwards through the first and second filters downstream of the first and second mixing reactors.
