UV Water Treatment System for commercial and industrial use
Made of high quality stainless steel and comprise of s/s chamber containing a germicidal lamp and quartz sleeve plus a separate electrical box which allows flexibility for fitting.<o:p>
<o:p>
When selecting an ultraviolet system care must be taken to choose a model that is powerful enough to treat the flow required. If the flow is faster than specified the water passes through the chamber too fast for the rays to effectively kill all the bacteria<o:p>
Micro organisms including bacteria, viruses and cysts are all around us naturally. Many are harmless but exposure to "bad" ones can cause severe illness particularly in the elderly and very young. There is a wide variety of water treatment products available to improve taste, clarity, scale etc but none of these are designed to combat bacteria. Ultra violet water treatment is one of the safest ways to disinfect water as the UV rays are a natural component of sunlight. No chemicals are added so there is no danger from overdosing or creating a bad taste
Advantages:
There are several advantages of using UV water filtration system rather than a chemical disinfection solution (such as chlorination):
1.No known toxic or significant nontoxic byproducts
2.No danger of overdosing
3.Does not require storage of hazardous material
4.Adds no smell to the final water product
5.Requires very little contact time
UV treatment for water purification and drinking water has many advantages. In addition to high water quality (no risk of Legionella/example), UV disinfection system for water treatment is very reliable and easy to use.
Flow rate
Shortening or lengthening UV exposure time (dwell time) determines the effectiveness and use of a UV sterilizer. Adjusting the flow rate through the sterilizer controls UV exposure time. In general, larger organisms will need a longer dose of radiation than smaller organisms. For example, a UV sterilizer set at a higher flow rate is capable of controlling bacteria and free-floating algae but may not be effective against parasites. Reduce the flow rate through the UV sterilizer to lengthen the time parasites are exposed to the UV light. With a slower flow rate, the same unit can now be used to help control parasites.<o:p>
Bulb age
Lamp effectiveness declines with time. Compared to when it was new, your UV sterilizer will no longer produce the same results after months of use. Therefore, you may have to increase the dwell time (by lowering flow rate) to produce desired results. Replace the UV bulbs every 6 months, or per manufacturer's recommendation, in order to maintain UV efficiency. Also, clean the quartz sleeve of the lamp regularly to remove organic buildup. A clean quartz sleeve allows better penetration of UV light and maximizes the efficiency of the unit.<o:p>
What Contaminants Do UV Sterilizers Remove?
There are no micro-organisms known to be resistant to UV, unlike chlorination. UV is known to be highly effective against bacteria, viruses, algae, molds and yeasts, and disease causing oocysts like cryptosporidium and giardia. In practice, bacteria and viruses are the cause of most major waterborne pathogenic diseases. Of these enteric viruses, hepatitis virus and Legionella pneumophila have been shown to survive for considerable periods in the presence of chlorine, but are readily eliminated by UV treatment. For most microorganisms, the removal efficiency of UV for microbiological contaminants such as bacteria and virus generally exceeds 99.99%.
How is a UV sterilizer installed?<o:p>
The UV sterilizer should be the last piece of equipment in the system before the water is returned to the aquarium. It should be preceded by the biological and mechanical filters, and any chemical filter or heat exchanger in the system. Follow the manufacturer's directions on installation. Most units use hose barb connectors to attach to the appropriate water pump or are designed to allow add-on connectors as a PVC slip fit or hose barb attachment.<o:p>
What is the proper maintenance schedule for UV sterilizers?<o:p>
The quartz sleeve will need to be checked monthly and removed and cleaned with rubbing alcohol. Some larger UV sterilizers have wiper mechanism units installed for easier maintenance.<o:p>
For most units, the UV bulb will need to be replaced after 6 months of continuous use, however, this time may vary so be sure to follow the manufacturer's recommendations. When installing or changing a bulb, never look directly at the bulb when the unit is turned on. Doing so can result in permanent damage to your eyes. (The damage can occur without you feeling any discomfort.)<o:p>
Always disconnect the unit from the electricity when performing maintenance to protect against possible shock. When turned on, the bulb becomes especially hot when in the air and submerging it in water may cause it to break.<o:p>
Product application
Applications include private wells, campgrounds, hotels, bottlers, aquaculture, hospitals, food, cottages, restaurants, breweries, water systems, laboratories, marine, pharmaceutical, dairies and many other applications.

Q. Are UV sterilizers a good replacement for biological and mechanical filtration?
A. NO. UV sterilizers are not a replacement for good biological and mechanical filtration, regular water changes, or proper control of the nitrogen cycle.
A properly selected UV sterilizer can help clarify water, rid free-floating algae, and control outbreaks of harmful bacteria and certain parasites.
Q:WHY DO THEY WORKS
A:The high germicidal power of this wave length must be sought in DNA and in the link of its fundamental components (nucleotids). DNA is a macromolecule present in all living organisms in which all information necessary for life and reproduction reside. The alteration, induced by the UV-C irradiation, of some chemical links present among nucleotids is able to change the information contained and conveyed by DNA, these alterations prevent its normal activity and this irreversibly leads to the cellular death.
Q:WHY THEY ARE CONVENIENT
A:Among the several advantages offered by this kind of technology we mention:
- environmental treatment (without addition of chemicals, without alteration of taste)
- no danger of over-dosing and no alteration of the characteristic of water
- quick action (without any stocking tank) the time is the one of passing through the sterilizer
- compatibility with the other technologies (filtration, softening, etc) for a complete treatment of water
- cheapness and practicalness thanks to the low consumption of electrical energy and to the little required servicing
UV treatment for water purification and drinking water has many advantages. In addition to high water quality (no risk of Legionella/example), UV disinfection system for water treatment is very reliable and easy to use.
