G01N 15/02
US Classification:
73 6171
Abstract:
A method for monitoring water in a distribution system is disclosed where the sensor sampling schedule is changed in real time in response to a contaminant or other chemical passing through the sampling location. This results in finer determination of where the contaminant is located in the water distribution and identification of the contaminant with a lower false rate than random or scheduled sampling.

US Classification:
356 73, 356417, 356418, 356419, 2504581
Abstract:
A method and apparatus for monitoring water and other fluid systems is described. The fluid is continually monitored spectrophotometrically by measuring many optical parameters in an in-line, on-line system, which compensates for normal fluid changes while detecting abnormalities.

International Classification:
C02F 1/48
US Classification:
210748000
Abstract:
Biocolloids, e.g. oocysts, are removed from water by filtration using a packed bed of a granular filter medium, preferably MgO, establishing an electric field across the packed bed, perpendicular to the flow of the water through the packed bed. The packed bed is provided in an annular space between two concentric electrodes.

Abstract:
An apparatus for measuring the impurity content of drinking water processes has a monochromatic light source projecting a beam of visible light toward a light trap. A water sample generator passes a water sample transverse to and intersecting the beam of light. A photo sensor array with an angular resolution of at least 0.10 detects forward scattered light from particles in the water sample. A data acquisition and processing system connected to the photo sensor array receives signals of the intensity of scattered light as a function of the scattering angle and compares the received light intensities to stored patterns of known waterborne contaminants. Based upon detected contaminants and their concentrations, the data acquisition and processing system provides an output on a connector which can be used to control a water processing system to adjust treatment of drinking water for contamination such as bacterial pathogens.

Abstract:
A mobile treatment system is provided for treating contaminates in water, particularly during emergency situations such as natural disasters and planned attacks. The mobile treatment system includes a mobile framework; one or more treatment modules mounted on the mobile framework; a piping system in fluid communication with the one or more treatment modules, said piping system comprising one or more pumps configured to convey water to and from the one or more treatment modules; and at least one power source to provide power to the one or more pumps and one or more treatment modules. The treatment modules may include pre-filtration, chlorination treatment that generates chlorine by electrolysis, activated carbon treatment, and treatment using a disinfecting, silver coated composite material.
