Automatic Cleaning 80m3hour UV Water Sterilizer for Water Supplying

 
UV Water Sterilization technology seeks to use the same process as nature to provide water that is completely safe. In nature, the Sun produces UV rays which have a germicidal effect on disease causing pathogens in water. When these contaminants are exposed to UV light, they are rendered harmless and the output water is considered disinfected.

UV water purification systems kills 98% of all bacterial contaminants, and provides clean, safe drinking water, far exceeding Health Department standards for potable water.


UV water sterilizers use several stages of filter to remove sediments down to 5 microns removing particulates. A second stage carbon filter removes odors and particles down to 0.5 microns. The UV light stage saturates the water with high dose UV light at wavelengths that kill pathogens. Together the UV water sterilizer system is excellent for quality of construction, and effectiveness in treating your water to remove unwanted and unsafe elements. The UV water treatment system is ideal for homes, businesses, and remote sites.   





Where Did UV Sanitizers Get Their Start?
The UV light spectrum was discovered with the identification of light waves. Scientists have known for almost a century that UV is a powerful neutralizer of algae, bacteria and viruses. They also discovered that the optimal ultraviolet wavelength to destroy microorganisms was between 250 and 270 nm. The results led scientists to incorporate Ultraviolet sanitizer technology into sterilizing drinking water more than 30 years ago. Ultraviolet disinfection has since gained in popularity in drinking water and wastewater disinfection in the last 10 years. Now ultraviolet sanitizers disinfect a significant percentage of all drinking and wastewater. The big news is that New York City has designed the world's largest drinking water facility, capable of treating two billion gallons per day. New York will install twelve thousand ultraviolet lamps - the same type of lamps found in SpectraLight UV sanitizers.



UV sterilization affects waterborne contaminants and disease causing pathogens with a
99.9% kill rate. The result is high quality water exceeding all health department standards.
Factors Affecting UV Treatment:
Because UV does not leave any measurable residue in the water, it is recommended
that the UV sterilizer be installed as the final step of treatment and located as close as
possible to the final distribution system. Once the quality of the water source has been
determined, you will need to look at things that will inhibit the UV from functioning
properly (i.e. manganese, TDE, turbidity and suspended solids).
Iron and Manganese will cause staining on the quartz sleeve and prevent UV energy
from transmitting into the water levels as low as 0.03 ppm of iron and 0.05 ppm of manganese. Proper pre-treatment is required to eliminates this staining problem.

Total Dissolved Solids (TDS) should not exceed approximately 500ppm. There are many
factors that make up this equation, such as the particular make up of the dissolved solids
and how fast they absorb the available UV energy. Calcium and magnesium, in high
amounts, has a tendency to build up on the quartz sleeve, again impeding the UV
energy from penetrating the water.
Turbidity: is the inability of light to travel through water. Turbidity makes water cloudy and
aesthetically unpleasant. In the case of UV, light levels over 1NTU can shield microorganisms from UV energy, making the process ineffective.
Suspended Solids: need to be reduced to a maximum of 5 microns in size. Larger solids
have the potential of harboring or encompassing the micro organisms and preventing
the necessary UV exposure. Pre-filtering is a must on all UV applications to effectively estroy micro organisms to a 99.9% kill rate.
 
How Ultraviolet Pool Sanitizers Work

SpectraLight is installed in-line just after your pools existing filtration system. SpectraLight bombards the passing water flow with a high intensity germicidal ultraviolet ray that destroys more than 60 waterborne pathogens, including algae, bacteria, cysts, and viruses. The UV sanitizing lamp is housed in an industrial graphite housing optimized for high flow rates. A highly specialized quartz glass sleeve protects the lamp from passing water while transmitting 99.9% of the UV light. The highly concentrated electromagnetic energy destroys organic matter and eliminates the formation of dangerous chlorine by-products called chloramines that commonly lead to red, stinging eyes, skin irritations, asthma and allergies. This energy penetrates the cell walls of bacteria, viruses, algae, cysts and all pathogens. That's right: no pathogen can escape a powerful dose of UV from a SpectraLight sterilizer.
 

Limitations in UV Water Filters

As remarkable as the technology is, ultraviolet water purification by itself is not enough to render water completely safe for drinking purposes. That's because UV radiation works only on microorganisms such as bacteria and viruses. UV light is of little use in eliminating other contaminants in water such as chlorine, heavy metals and VOC's (Volatile Organic Compounds).
VOCs are toxic, man-made chemicals that leach into ground water during the manufacture of products such as paints, petroleum products and refrigerants.

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.

 Technical parameters sheet  installation instructions

1.Before install this equipment,please test the voltage for connection.normal running for UV lamp and ballast requires 240V.
2.There should be a 1.5 meter space for spared at each end(at least one end)for disassemble the quartz tube and UV lamp.then connect the water inlet and outlet
3.After connected the inlet and outlet pipe,then release the water to check whether there is any leakage at the nut connection.if it is leakage,screw the nut or check the sealing ring is cracked or not.pipe.please do not use too much force when screw the nut to avoid any cracking of tube.
4.The supporting frame must be grounding.
5.The UV lamp is inserted into the quartz tube through the nut with holes. the electric control panel is connected with 4-core plug and UV lamp. while connecting, two hands should handle the pin end and 4 core plug end respectively. Insert into  plug slowly to avoid possible break-up because of corrosion.
