Ultraviolet disinfection of the treated effluent ensures the protection of the environment for direct discharge application or disposal by means of spray irrigation.  The Model AT 1500 Ultraviolet (UV) disinfection system provides reliable treatment without chemical addition.  The Model AT 1500 UV disinfection system reduces harmful pathogenic bacteria levels to below recreational water quality standards, particularly with the high quality effluent provided by Singulair treatment systems.  The compact design of the system minimizes the amount of excavation required making installation quick and easy.  Ultraviolet disinfection is routinely used in ecologically sensitive areas where residuals from chemical disinfection could possibly create problems in the receiving environment.

The Model AT 1500 UV disinfection system is equipped with an internal current sensing circuit that continuously monitors the performance of the UV lamp.  This self-diagnostic feature monitors the current that is used by the UV lamp.  If the ultraviolet lamp output drops below an acceptable level for proper disinfection, the alarm circuit will turn “off” the green LED located on the outside of the control center and generate an alarm signal.  If the disinfection system is connected to a Service Pro control center, the service provider is immediately notified of the alarm condition and a UV disinfection alarm code is registered in the service history database.

All electrical components are contained in a NEMA 4X weatherproof enclosure.  The lighting ballast is also contained in the electrical enclosure to assure maximum life.  For safety, a power interlock switch is included to automatically de-energize the system during service and routine maintenance.
