110 results about "Portable water purification" patented technology

Portable water purification devices are self-contained, easily transported units used to purify water from untreated sources (such as rivers, lakes, and wells) for drinking purposes. Their main function is to eliminate pathogens, and often also of suspended solids and some unpalatable or toxic compounds.

Ultraviolet water purification system

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.

Portable water purification system using one or more low output power UV light sources

A water purification system includes one or more germicidal UV light sources that operate within an amplifying chamber that contains a given amount of fluid as a batch or as flowing through the chamber at any given time. The amplifying chamber has a highly reflective inner surface that redirects the germicidal UV light that reaches the highly reflective inner surface back through the fluid simultaneously in substantially all directions. A power source drives the one or more UV light sources to provide to the fluid contained within the amplifying chamber a fraction of the total UV energy that is required to purify the given amount of fluid. The amplifying chamber repeatedly redirects the UV light that reaches the highly reflective inner surface back into the fluid, to provide a dose required to purify the fluid.
