UV Dose
OS units ensure a high UV dose in a wide range of water transmission values.
The minimal dose for effective disinfection is sustained throughout the lamp's
life including lamp aging losses and quartz sleeve foiling.
UV lamps
All OS units are equipped with newest, industrially manufactured high
intensity amalgam lamps having long service life (up to 10 000 hours of
continues operation ). The lamps were developed by LIT engineers especially for
water disinfection. These lamps have three times more UV intensity than
conventional mercury low-pressure lamps. Low depreciation of UV radiation
intensity at the end of lamp life, less than 20%, guarantees effective
disinfection throughout the operating period of OS units. The UV spectrum of the
lamps is optimal for germicidal effect.
Control system
PLC based Control System continuously monitors UV dose inside the UV reactor,
the status of each UV lamp including elapsed operating time. All operating data
are displayed on the LCD panel. The plastic or stainless steel enclosure of
Control system has IP65 protection class.
Cleaning system
OS units can be equipped with optional chemical cleaning system. The purpose
of chemical cleaning systems is the removal of inorganic and organic coating
from the surface of protective quartz sleeves. Chemical cleaning ensures the
proper level of UV intensity inside the reactor and provides reliable
disinfection throughout the operation lifetime of the UV system.
Installations
By customer request an optional stainless steel frame can be supplied for
easy assembling and compact installation of OS system components (UV reactor,
Control Cabinet, and Chemical cleaning).
LIT Technology and/or its representatives provide technical consultations on
installation, operation and service of OS units.
Application
LIT has developed OS series UV systems for industrial/commercial applications
in wastewater disinfection. The models in this series have packaged design with
all components integrated in a compact stainless steel housing and separate
control cabinet. LIT OS series units utilize amalgam low-pressure germicidal
lamps of high-output that produce short-wave radiation at 254 nm wavelength
which kills bacteria, viruses and other microorganisms in water.
Design
and manufacturing process of OS units comply with international standards for UV
disinfection of potable water such as German DVGW 294.
