    Abstract: An embodiment provides method for controlling lamp output within an array of lamps, including: receiving sensor data corresponding to one of a plurality of lamps within the array, wherein the sensor data comprises an irradiance value from at least one of: within a lamp sleeve and an irradiance value from outside a lamp sleeve; identifying, based the sensor data, a change in an output of the one of the plurality of lamps; sharing the sensor data with other of the plurality of lamps within the array; and adjusting, in response to the sharing, an output of at least one of the other of the plurality of lamps within the array, thereby compensating for the change in the output of one of the plurality of lamps. Other aspects are described and claimed.

    Abstract: An embodiment provides a method for making a non-hazardous iron product for treating wastewater, including: adding sodium bisulfite to a solution comprising iron, creating an aqueous solution; adding an amount of sodium hydroxide to the aqueous solution to increase the pH of the aqueous solution to between 2-2.5; determining an amount of sodium bicarbonate and adding the identified amount of sodium bicarbonate to the aqueous solution, wherein the sodium bicarbonate adjusts the pH of the aqueous solution to a desired pH; and providing a buffer to the aqueous solution to generate a slurry. Other embodiments are described and claimed.

    IPC: C02F1/32

    Abstract: Methods of operating a system for treating a fluid flowing through a reactor with ultraviolet (UV) light emitted from a light source assembly. One method includes detecting, with a flow sensor, a flow rate of fluid through the reactor; and controlling, with a processor, electric power supplied to the light source assembly so that a low average amount of electric power is supplied when the flow rate is below a threshold. In another method, an intensity of the UV light may be controlled by the processor based on a detected temperature in the light source assembly. Yet another method includes determining that the flow sensor is defective based on the detected temperature in the light source assembly and the detected flow rate. A further method includes determining that an intensity sensor is defective based on a detected intensity and the detected temperature in the light source assembly.

    Abstract: A radiation source assembly comprises a source base, a UV transparent sleeve, and a UV lamp. The source base comprises a sealed electrical connection interface and an opposing sealed sleeve interface. The sealed electrical connection interface comprises a electrical contacts and the sealed sleeve interface comprise a radial sealing element, an outer collar, and a compression ring. The UV transparent sleeve is engaged with the sleeve interface such that the radial sealing element of the sealed sleeve interface is disposed between the UV transparent sleeve and the outer collar of the source base, and the compression ring is positioned over the UV transparent sleeve and engaged with the source base to compress the radial sealing element onto the UV transparent sleeve and the outer collar. The UV lamp is disposed within the UV transparent sleeve and electrically coupled to the electrical contacts of the electrical connection interface.
