  • Page 8: System Overview

    YSTEM VERVIEW 4-Log Virus Reduction The PRO24-186 system provides over 186 mJ/cm UV dose for 4-log reduction of viruses, including the Adenovirus. The system consists of two chambers in series utilizing amalgam UV lamps, CoolTouch , and LightWise technology. The Adenovirus system is fully third-party validated to USEPA UV Disinfection Guidance Manual (UVDGM) protocol for 4-log Adenovirus reduction.

Therefore, the system can physically exceed 24 GPM;...

  • Page 10: Dose Alarm Selection

    3.3.2 Dose Alarm Selection VIQUA’s Adenovirus system comes equipped with real-time UV dose monitoring which utilizes data from both the UV sensor (3.3.3) and the flow meter (3.3.5). The system will go into alarm at different points depending on input from these components. There are two dose settings to choose from: variable or stepped dose alarm.

  • Page 11: Uv Sensor

    In this way, the UV sensor detects when the water flowing furthest away from the lamp is no longer being disinfected properly due to any factor. VIQUA’s UV sensors reliably detect low UV output and identify the need for maintenance via a 4-20 mA output signal to the controller.

  • Page 12: Sensor Response Curve

  • Page 13: Controller Interface

    Set points depend on the Dose Alarm Selection (sec. 3.3.2). The controller’s alarm conditions act independently of the COMMcenter (sec. 3.3.7); though the Adenovirus PRO24-186 should always be operated with the COMMcenter this means the UV disinfection dose is monitored even if the COMMcenter should fail.

  • Page 14: Uv Lamp

    The lamp produces germicidal ultraviolet light (UV-C) at a wavelength of 253.7 nm. The absence of a peak at 185 nm is significant because it means no harmful ozone will be produced. VIQUA’s amalgam lamps have a mercury content of less than 15 mg (IMERC registered).

    Product Features and Benefits 3.5.1 LightWise™ Technology VIQUA’s new LightWise™ technology allows the system’s electronic controller to automatically reduce lamp power during periods of no water flow. In order to maintain dose levels above alarm setpoint values, the controller will dim to 62% power output.
