Provided herein are portable ultraviolet (UV) devices, systems, and methods of use and manufacturing same. Methods of use include methods for UV disinfection and sterilization, more specifically, methods for UV disinfection and sterilization of a container, a room, a space or a defined environment. The portable UV devices, systems and methods are particularly useful for the UV disinfection and sterilization of a container, a room, a space or defined environment used in the food, beverage and dairy industry and in the process of fermentation for an alcoholic beverage. Provided are also portable UV devices, systems, and methods for inhibiting the growth of one or more species of microorganisms present in a container, a room, a space or a defined environment, preferably for inhibiting the growth of one or more species of microorganisms present on an interior surface of a container, a room, a space or a defined environment.

This invention relates to a method, process and apparatus for disinfecting and sterilizing all types of surfaces contaminated with microorganisms and toxic substances to render both inactive. Furthermore, this invention relates to both a method and apparatus for disinfecting and/or sterilizing breathable air and then using this air to protect a confined space from external contamination. The apparatus consists of a new ultra-violet (NUV) source that is more effective than mercury based 254 nm light for destroying DNA of virus, bacteria, spores and cists. It is most effective in breaking chemical bonds in toxic gases and Biotoxins that are useful to terrorists. It is combined with other apparatus that remove particulates and byproducts sometimes produced by the NUV source and maintains positive pressure of the confined space so as to prevent the influx of air from outside the protected zone.

A liquid treatment device includes a base with a power source, a UV-LED module for providing UV-B or UV-C light to liquid, an LED for providing visible light, and a processor for selectively powering the UV-LED module and the LED, and having a UV transmissive material above the UV-LED module for allowing the UV-B or UV-C band light from the UV-LED module to be transmitted from the base housing, and a liquid storage housing removably coupled to the base housing with a storage portion configured to hold liquid and having a bottom portion comprising a UV transmissive material for allowing the UV-B or UV-C band light from the UV-LED module to be transmitted into the liquid, and an output coupled for restricting outflow of the liquid from the storage portion.
