Complete Norweco AT1500 UV Unit. 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 system.
The Model AT 1500 Ultraviolet (UV) disinfection system provides reliable
treatment without chemical addition. A complete treatment unit, the
Model AT 1500 UV disinfection system reduces harmful pathogenic bacteria
levels below bathing water quality standards, particularly with the
high quality effluent provided by the Singulair Bio-Kinetic Wastewater
Treatment Plant. 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 the optional Service
Pro control center, the system owner and service provider are
immediately notified of the alarm condition and a UV disinfection alarm
code is registered in the service history data base.
The Model AT
1500 UV disinfection system is designed to provide long service life.
It is recommended that the disinfection sub-assembly be removed and
serviced every six months by a factory trained service technician. To
insure proper disinfection, the UV lamp should be replaced every two

Advantages of the Norweco AT 1500:
Dual-pass design assures the integrity of the treatment process. All
liquid flowing through the system is treated twice by the UV lamp, once
on the way down and again on the way back up. This doubles the exposure
to the UV light and greatly improves the treatment.
electrical components are contained in a NEMA 4X weatherproof electrical
enclosure. These components control the disinfection process and assure
treatment integrity. The gasketed cover is secured with screws to seal
Our long-life lamp is designed and tested to be
superior to competitive products currently used in onsite wastewater
treatment. The bulb is stronger and provides more complete disinfection.
The lighting ballast is contained within the gasketed electrical
enclosure to assure maximum life. Competitive systems leave the ballast
exposed to the treatment environment.
Disinfection quality is
assured by a corrosion resistant solid state circuit board that
continually monitors system performance. A current sensing circuit
within the controls automatically gives immediate notification should a
service interruption occur.
Easy to install and maintain. The
entire UV process is contained within a convenient ABS treatment
chamber. Optional concrete or high-density polyethylene enclosures are
also available to provide additional treatment.
residual or harmful by-products. The AT 1500 UV treatment system
provides superior disinfection and its performance is independent of the
pH, temperature, and ammonia content of the effluent being treated.
Low electrical usage. The high efficiency electrical controls use very little electricity.
Inexpensive to install and operate. The AT 1500 can be installed for
less than some chemical feed systems, and requires no recurring
chemical purchase. The only maintenance requirement is periodic cleaning
of the Teflon cover and lamp replacement every two (2) years.
Can be used to eliminate contaminates not readily removed by chemical
treatment. Advanced Oxidation Processes (AOP) can be constructed by
supplementing the AT 1500 system with ozone or H2O2 to remove chemical
resistant pollutants, such as certain pharmaceuticals and methyl
tertiary butyl ether (MTBE).
