China Commercial Ultraviolet Water Sterilizer Systems UV Disinfection Equipment

Specification:
Ultra violet radiation is natural source of purification.
Ultra violet radiation band of invisible light in the electromagnetic spectrum, in the range of 200 - 400 nm wavelengths.
The U.V. wavelength of 253.7 nm possesses the greatest germicidal effectiveness, which Penetrate the microbial cell membrane to destroy the DNA molecule thus preventing cell Replication.
U.V. is used to provide Bacterial Disinfection in water. It does not change the Physical or Chemical Characteristics in water. U.V. provides disinfection On Contact. It does not have any residual properties left in treated water.
Special High Germicidal Lamps produce high U.V. output in 254 nm range.
There are no know micro organisms resistant to U,V,
U.V. water purification is preferred the world over because it is the simplest & most practical means of destroying micro organisms in water.
Advantages of UV sterilizer
No chemicals added to the water supply - no byproducts, (i.e. chlorine + organics = trihalomethanes).
Environmentally and user friendly, no dangerous chemicals to handle or store, no risks of overdosing.
Easy installation, only two water connections and a power connection.
No change in taste, odor, pH or conductivity or the general chemistry of the water.
More effective against viruses than chlorine.
Extremely economical, hundreds of gallons may be treated for each penny of operating cost.
Immediate treatment process, no need for holding tanks, long retention times, etc.
Automatic operation without special attention or measurement, operator friendly.
Simplicity and ease of maintenance, periodic cleaning, (if applicable), and annual lamp replacement, no moving parts to wear out.
No handling of toxic chemicals, no need for specialized storage requirements.
Low initial capital cost as well as reduced operating expenses when compared with similar technologies such as ozone, chlorine, etc.
How Ultraviolet Disinfection System Works
As water flows past the UV lamp(s) in a UV disinfection system, microorganisms are exposed to Ultraviolet light energy. Ultraviolet light alters the DNA material in cells so that bacteria, viruses, molds, algae and other microorganisms can no longer reproduce. The microorganisms are considered dead, and the risk of disease from them is eliminated. These Ultraviolet Disinfection Systems are designed for commercial & industrial applications. The process of UV Disinfection is accomplished without adding any harmful chemicals to your drinking water and does not distort the water or effect its pH value. UV Disinfection has an effective kill rate of 99.99% of most living microorganisms such as bacteria & viruses.
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%.

Typical Maintenance Requirements
UV lamps (bulbs) require annual replacement to ensure optimal performance. UV lamp performance, just like any other light source, will slowly diminish over time. Beyond one year, there is no assurance that the UV light emitted from the bulb will provide sufficient disinfection. Remember, UV light cannot be seen. The bulb may still produce light, but not necessarily UV rays. The quartz sleeve does not need replacement unless it gets broken, however, it should be cleaned several times per year (outside only).
Frequently Asked Questions about Ultraviolet (UV) Purification
Q. How do ultraviolet ("UV") sterilizers work?
A. UV sterilizers work by exposing water to powerful germicidal ultraviolet light. DNA and protein links in bacteria are destroyed by exposure to this light.
Q. Does the water become radioactive by this radiation?
A. No. No radiation residual or any chemical residual is left in the water as a result of the UV rays.
Q. Do these systems come in different sizes?
A. Yes. The size of the systems is directly proportional to the flow rate of the water in gallons per minute. The higher the flow rate, the larger the system and lamp.
Q. Does the water have to sit in the UV sterilizer to be disinfected?
A. No. If the system is sized correctly, the water is disinfected as it flows through.
Q. What if the water flows faster than is allowed through the system?
A. If the flow rate exceeds the design flow rate of the UV sterilizer, then there is a possibility that the water will not be properly disinfected. It is important to use a flow restrictor so that the flow rate cannot be exceeded.
Q. How long does the lamp last?
A. The lamps last approximately 10,000 hours. That is why we recommend replacement approximately every 12 - 14 months of continuous operation. After this period, the lamp itself becomes solarized and blocks the rays form entering the water.
Q. Are these systems bigger energy users?
A. No. The 12 gallon per minute model, for instance uses only 39 watts, about half the amount an ordinary light bulb uses.
