A fluid sterilization apparatus according to an embodiment includes a tubular cover; a tubular portion provided inside the cover; a supply head provided at one end of the tubular portion; a discharge head provided at the other end of the tubular portion; at least one light-emitting element provided in at least one of the supply head and the discharge head and allowed to irradiate an inside of the tubular portion with ultraviolet rays; and a temperature control unit capable of controlling a temperature of a space between the cover and the tubular portion.

An ultraviolet irradiation unit of the present invention includes a plurality of ultraviolet irradiation modules arranged and spaced apart from each other at intervals. Each of the ultraviolet irradiation modules includes a light source emitting ultraviolet rays, and a reflector arranged on an ultraviolet emission side of the light source and reflecting part of the ultraviolet rays emitted from the light source toward the object to be processed.

A smart device to store resource being proposed. The resource may available in any state of matter. The smart device has built-in self-learning-based sensors and modules to measure, identify and purify the resources. Device has self-generating, built-in electricity generation and rechargeable battery modules. In one of the embodiments, the resource is available in liquid form, say water and the storage unit may be available in a transparent or opaque or colored unit. Smart sensors with chemical, Ion, bio feature sensing parameter are being embedded in the device with appropriate electronic modules. Resource is purified by various methods such as filtering, heating, Nano particle coating, smart magnets, additives of mineral enhancers, smart electrodes of different materials and electromagnetic wave and ultrasound treatments. Smart display would display various water quality parameters, such as temperature, oxygen and purity level, and diagnostic and prognostic information about resource and smart modules.
