UV Sterilizers

Ultraviolet water treatment systems (UV sterilizers) kill bacteria in water. They are often used to ensure safe drinking water from well, spring and borehole water supplies. Due to increased legislation are now regularly used in food and drink related industries. 
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.

UV specification
Product application
Ultraviolet light treatment is a widely recognized and proven method of disinfection of water and has several advantage over other disinfection methods such as chlorination, ozonation, etc.UV light does not add anything to the water ,such as ,undesirable color ,odor , taste , or flavor ,nor does it generate harmful byproducts. It adds only energy in the UV radiation. Also, UV disinfection requires only a fraction of the contact times required by other disinfection methods. It is fast, efficient, effective, economical and environmentally-friendly.
 
Principle of Operation
UV water disinfection system design has been carefully conceived to provide adequate germicidal dosage throughout the disinfection chamber. The dosage, as it applies to UV disinfection, is a function of time and the intensity of UV radiation to which the water is exposed. Exposure time is related to the flow rate, the higher the flow rate, the lower the exposure time or the lower the flow rate, the higher the exposure time. The UV intensity is the amount of energy, per unit time, emitted by germicidal lamp. The Dosage is the product of UV intensity and the exposure time.
 
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.
 
Water Quality (in)
Water quality plays a major role in the transmission of germicidal UV rays. It is recommended that the water does not exceed following maximum concentration levels
 
Effectively treating water with higher concentration levels than listed above can be accomplished, but may require added measures to improve water quality to treatable levels. If, for any reason, it is believed the UV transmission is not satisfactory, contact the factory.
UV wavelength (nm)
 
                 DOSAGE is the product of intensity & time
dosage=intensity*time=micro watt/cm2*time=microwatt-seconds per square centimeter
                              (μW-s/cm2)
               Note:1000μW-s/cm2=1mj/cm2(milli-joule/cm2)
