Abstract:
A system for disinfecting a fluid, including: a flow cell including one or more inlet ports and one or more outlet ports, wherein the flow cell is configured to communicate a fluid containing a biological contaminant from the one or more inlet ports to the one or more outlet portions through an interior portion thereof; and one or more point radiation sources disposed about the flow cell, wherein the one or more point radiation sources are operable for delivering radiation to the biological contaminant; wherein an interior surface of the flow cell is operable for reflecting the radiation delivered to the biological contaminant by the one or more point radiation sources; and wherein the interior surface of the flow cell is operable for reflecting the radiation delivered to the biological contaminant by the one or more point radiation sources such that a radiation intensity is uniform throughout the interior portion of the flow cell. In one exemplary embodiment, the flow cell is an integrating sphere. Optionally, the system also includes a photocatalyzing material disposed on at least a portion of the interior surface of the flow cell.
Abstract:
An Ultraviolet-C (UVC) based portable water purification system employing a novel array of baffles increases the efficiency per unit energy of irradiating UVC light in the eradication of pathogens in the water. Closed loop feedback allows monitoring the application of UVC light power to ensure high levels of pathogen eradication. This system is capable of eradicating a wide range of waterborne bacteria, viruses, protozoa, helminthes, yeast, and mold found in natural freshwater sources worldwide. By adding pre- or post-filters, the system can remove harmful organic compounds, pesticides, inorganic compounds and heavy metals from the water. The system can also be used to eradicate pathogens in fluids other than water. As a feature of this invention, a communications systems that can reach geographically dispersed populations at low cost without the need to install costly wired communications infrastructure is combined with and powered by the water purification system. In one embodiment, a packet radio system is provided to create nodes in a wireless mesh communications system to provide voice, data, video and internet communications using an array of the water purifiers to create a wireless mesh network.
Abstract:
PROBLEM TO BE SOLVED: To provide an ultraviolet irradiation water-treatment apparatus having high irradiation efficiency of ultraviolet ray. SOLUTION: This ultraviolet irradiation water-treatment apparatus (10) comprising a container (20) having a cylindrical side surface part (21). A plurality of bar-like ultraviolet lamps (30A) to (30F) are installed in the container (20) so as to be parallel with the center axis (S) of the side surface part (21). An inlet tube (22) for running the water to be treated (W1) into the apparatus is provided onto the outer wall of the side surface part (21) at a position along the tangential direction of the inner periphery of the side surface part (21).
