Advantages

UV light will kill any DNA based micro organism when give enough UV dosage.

UV break micro organism’s DNA in a cumulative basis.

Continuous disinfection in cooling water. If micro organism is not effectively deactivated on the first disinfection cycle and in the next cycle it get UV treated.

For 90% kill algae 30000 μWs/cm2 is required for one cycle .

UV spectrum between 185-400nm has a strong germicidal effect, with peak effectiveness at 265nm.

UV works instantaneously against all water-borne microorganisms, including bacteria, viruses, molds, spores and protozoa – including those resistant to chlorine.

UV systems are also very easy to use and can be effectively monitored and integrated with online process control systems.

UV disinfection systems are very compact, modular and easy to 

install into existing water treatment systems.

UV does not cause the formation of chemical disinfection by-

products, many of which can have undesired effects of their own.

UV sterilizer is eco-friendly and cost effective.

Optimal service condition:

As UV is a short- wavelength light wave, it has low radiant energy and weak penetrating power

and can only kill the microorganisms it directly radiates on. Therefore, in order to enhance the

bacteria-killing efficiency and ensure the security of drinking water, the incoming water into the

sterilizer must meet the following standard, (and if exceeding the following standard, the killing

efficiency may be affected).

How does UltraViolet light work on disinfecting water?

Ultraviolet (UV) light is one of the few FDA approved methods of disinfecting water. There are many 

benefits to UV systems versus chlorine disinfection such as : no chemical additives, no smell, no risk 

of overdosing, safer and easier to maintain.

The way it works is by allowing water to enter the chamber of the UV housing. Water never touches the 

lamp itself but moves around a quartz sleeve which protects the water from ever touching the actual lamp.

As the microorganisms get hit by the UV rays, their DNA gets damaged and they become "sterile" and unable 

to replicate. As they leave the UV housing and enter the home, it's important to understand that these microorganisms 

are still alive. However, these "sterilized" bacteria and viruses cannot replicate and therefore die over time or by our own 

body's white blood cells.

When you purchase a UV system, it's important to get proper pretreatment to ensure that the water is as clear as possible 

to ensure maximum effectiveness. Also, always buy a UV sterilizer that can handle more than your home's flow rate to ensure 

that your home is protected. Finally, UV lamps have a life span of about 9000 hours and should be replaced every year

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%. 

Specifically, the following are moved to an efficiency of greater than 99.99%:

E-coli

Salmonella typhl (Typhoid fever)

Salmonella enteritidis (Gastroenteritis)

Vibrio cholerae (Cholera)

Mycobacetrium Tuberculosis (Tuberculosis)

Legionella pneumophila (Legionnaires Disease)

Influenza Virus

Polio virus

Hepatitus A Virus (better than 90%)

Specifications:

Application

UV system is designed to treat flows ranging from 2-1136m3/h, and can be used for germicidal disinfection, ozone destruction, TOC reduction, and liquid sugar disinfection. It is suitable for indoor installation in locations including food and beverage processing plant, cosmetics and pharmaceuticals manufacturing, hospitals and laboratories, water treatment and community drinking water systems.

FAQ:

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.

Q.What is the proper maintenance schedule for UV sterilizers?

A.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.

Q:How is a UV sterilizer installed?

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.
