Ultra Violet Disinfection UV Sterilizer Unit
Advantage
Compared with other disinfection form, UV sterilizer has the following advantages:
1,High efficient sterilization: normally kill 99%-99.9% bacteria within 1 to 2 seconds.
2, Broad spectrum: UV rays has broadest spectrum, can kill almost all bacteria and virus.
3, No secondary pollution: don't add any chemical agent, so cannot create secondary pollution to water and ambient environment, do not change any ingredients in water.
4, Safe and reliable to operate: traditional disinfection technology such as adopting chloride or ozone,whose disinfection agent itself are highly toxic and flammable material. While UV sterilizer has no such potential safety hazard .
5, Low maintenance fee: UV sterilizer occupies a small area, structure requirement is simple, so total investment is smaller. Lower in operation, it costs only half than that chlorine disinfection in kiloton water treatment.
UVC systems virtually eliminate microbiological contaminants without using potentially hazardous chemicals. Water enters through the bottom port of the ultraviolet generator cell and swirls around a low pressure mercury vapor lamp, which emits powerful ultraviolet light energy at 235.7nm wave length. Bacteria, viruses and other micro-organisms absorb the light energy which disrupts their DNA, and are destroyed safely inside a factory tested stainless steel cell. The treated water then exits through the top port of the cell and is ready for consumption.
What does a UV sterilizer do?<o:p>
A UV sterilizer is used to control infections by stopping the spread of microorganisms from one fish/coral/invertebrate to another through the water. It is also used in pond applications to control free-floating algae. When operated correctly, free-floating microorganisms will be killed by the UV light. Note that the organisms must be in the water that flows to the UV sterilizer. The UV light has no residual effect and will not kill organisms attached to fish (e.g., adult stage of ich) or rocks (e.g., algae).<o:p>
How do UV sterilizers work?<o:p>
The UV sterilizer utilizes a germicidal fluorescent lamp that produces light at a wavelength of approximately 254 nanometers (2537 Angstroms). The water with the bacteria/algae passes over the bulb (or around the bulb if a quartz sleeve is used) and is irradiated with this wavelength. As the light penetrates the bacteria/algae, it mutates the DNA (genetic material), preventing growth/multiplication of the organism.<o:p>
In which types of systems should UV sterilizers be used and what are the benefits?<o:p>
A UV sterilizer may be used in any aquarium, however, in smaller aquariums (less than 24 gallons), the cost of the unit may make it impractical. UV sterilizers are most helpful in multiple tank systems that share a common filter. In a single tank system, they are beneficial in controlling the spread of an infectious disease if one occurs. This is especially true in heavily stocked tanks and those with large amounts of live rock and corals that could make catching and isolating a diseased fish difficult, or the use of certain medications contraindicated. Disease control is especially important when adding new fish to an established aquarium, since 98% of the hobbyists do not use a quarantine aquarium.<o:p>
In ponds, UV sterilizers are one of the best ways to control free-floating algae, allowing the pond owner to see and enjoy the fish. The UV sterilizer will also kill free-floating bacteria in the pond water.<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
Ultraviolet water purification systems are used in many applications that includes home/residential (both well water and municipal water supplies), commercial, and industrial. Here is a list of several applications where the power of UV water sterilizers are commonly used to treat and protect the water supply for contaminates such as bacteria and viruses. UV systems applications include private wells, campgrounds, hotels, bottlers, aquaculture, hospitals, food, cottages, restaurants, breweries, water systems, laboratories, marine, pharmaceutical, dairies and many other applications.
Limitation of Use
The UV water disinfection system NOT intended for the treatment of water that has an obvious contamination or intentional source, such as raw sewage, nor is the unit intended to convert wastewater to microbiologically safe drinking water.

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.
