Real Science . Not Science Fiction . Lamp Information
At Aqua Ultraviolet we chose to use ozone-emitting lamps after thorough testing with a radiometer, used to measure UV output (though we do offer a ozone free lamp if requested).
Our lamps are designed for 14 months of continuous use, we calculate our flow rates at 30,000 µw/cm² , based on the end of useful lamp life. Since we have calculated our flow rates based on the end of lamp life, there is no need to adjust the flow rates during life cycle of your lamp. Aqua Ultraviolet’s unit will perform at its optimum through out the life of the lamp and it just makes it simple.
Why are our flows so much more then our competitors? Because our units out perform our competitors hands down. Your water will not be green for very long, from over night to 3 to 5 days you will have crystal clear water.
Lamp Length
Our Competitor says that a longer lamp is more effective, however their own product line contradicts this statement. For example, their 25 Watt lamp is the same length as their 50 Watt lamp and they publish them at entirely different flow rates, how can that be? At Aqua Ultraviolet, we know that lamp length in itself doesn’t determine effectiveness, what does is the measurable UV output of the lamp. As an example, our new 400-Watt lamp, is only 4” long and run circles around lamps that are 20 times its size.
Aqua Ultraviolet first introduced the 100-Watt and 200-Watt lamps in the 90’s, at that time our competitor stance was, that it was impossible, those types of lamps do not exist. After seeing Aqua Ultraviolet’s success with these products EA now sells 120, 150 and 200-Watt lamps. Our competitors, plays follow the leader, watch and see, in a few years if their lamp manufacturer can copy our 400-Watt lamp, they too, will offer them.
Low Pressure vs. Medium Pressure
Aqua Ultraviolet offers a complete line of units that utilize low pressure, medium pressure and Amalgam lamps, dependent on the application, space available and project requirements.
Aqua Ultraviolet would like to give you just a little tid-bit of information as quoted from the EPA™ Waste Water Technology Fact Sheet on Ultraviolet Disinfection #832-F99-064
http://www.epa.gov/owmitnet/mtb/uv.pdf
“Medium-pressure lamps are generally used for large facilities. They have approximately 15 to 20 times the germicidal UV intensity of low-pressure lamps. The medium-pressure lamp disinfects faster and has greater penetration capability because of its higher intensity.”
Our competitor bases their cost comparison on a medium pressure lamp that needs to be changed in 1000 hours, however Aqua Ultraviolet medium pressure lamps last for 10,000 hours. This, of course, changes the equation entirely. It becomes much more cost effective to purchase the 400-Watt Unit.
“The average lamp life ranges from 8,760 to 14,000 working hours, and the lamps are usually replaced after 12,000 hours of use.”
Here’s a breakdown of Low Pressure vs. Medium Pressure (10 Lamps vs. 1 Lamp)
Low pressure for 400 Watt
10 Lamps - 40 Watt Lamps without quartz sleeves and seals $680.00
10 Seals – Should be changed with lamps $30.00
Quartz Sleeve -If you need to replace one they are $80.00 each>
Scheduled Maintenance Total $710.00
Aqua Ultraviolet 400 Watt Lamp
1 Lamp - 400 Watt Lamp with Quartz Sleeve and Seals $497.10
Scheduled Maintenance Total $497.10
Not only does the 400-Watt Medium Pressure Unit save on lamp changes, it also saves on space for installation. As an example a 400 Watt 10 lamp system would need approximately 4 feet in length, 4 feet in width, and 4 feet in height of space, because of the size we don’t even offer this as a viable option. On the other hand A 400 Watt Viper is 19-1/2 inches x 9 inches x 8-1/2 inches. The Viper is huge cost and space savings.
As quoted from The EPA™ Waste Water Technology Fact Sheet on Ultraviolet Disinfection #832-F99-064 EPA Fact Sheet
“At The GBWTP [Gold Bar Wastewater Treatment Plant in Edmonton Alberta Canada] a medium-pressure, high-intensity system was found to be more economical than the conventional low-pressure systems in both capital and life-cycle costs.”
