Today’s ultraviolet (
) systems, including those used in small community and industrial water systems, are far superior to yesterday’s legacy systems. But that doesn’t mean legacy systems are ready for the trash heap. Many UV systems that are 20 to 30 years old can still operate as well as they did when they were installed. They just require a little “TLC” to get them back to their original operating condition.
UV lamps. All UV units incorporate a single or multiple
(s), the units’ critical component, into their designs. Each unit requires periodic
Nails lamp replacement. While many lamps will continue to operate well beyond their stated life, a lamp’s performance declines if it operates for too long.
Typically, lamp replacement should be scheduled at no later than 4,000 to 5,000 operating hours for medium-pressure systems and 9,000 hours for low-pressure systems. Medium-pressure systems with variable output power settings will now achieve a 9,000-hour lamp life. Whatever system you have, do yourself a favor and don’t wait for the lamp to burn out before replacing it.
A physical process called solarization eventually blocks
from being emitted into the water stream, rendering it ineffective by preventing vital
Nails rays from penetrating the water stream. As a lamp becomes solarized, it turns slightly brown in color and should be replaced.
