Product Description
Aquiculture Water Disinfection Low Pressure UV Water Purifier
 
Overview
UV sterilization is actually a very simple process for inactivating unwanted free floating microscopic water borne bacteria, parasitic, fungal, viral, algae, and other unfriendly pathogens out of water by exposing it to high intensity ultra-violet (UV) light. UV radiation has three wavelength zones: UV-A,UV-B, and UV-C.UV light with wavelengths from 200-300 nm(UV-C) inactivates most microorganisms, with the greatest amount of inactivation occurring around 260 nm. A low-pressure mercury lamp resembling a fluorescent lamp produces the UV light in the range of 254 nanometers (nm). UV light has the ability to effect the function of living cells by altering the structure of the cells nuclear material, or DNA. The end result is the organisms die off, eradicating your water of these unwanted nuisances.

Application:
UV water sterilization is used in a wide variety of applications around the world including:
Aquiculture Water Disinfection Low Pressure UV Water Purifier
1. Residential Water Supply
2.Cottage Water Supply
3.Industrial Process Water
4. Laboratories
5. Bottling Plants
6. Food Processing
7. International Travel
8.Municipal Water Treatment
9. Military Camps
10. Relief Agency Camps
11. Emergency Preparedness

Factors Affecting UV Treatment:
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.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 solidshave the potential of harboring or encompassing the micro organisms and preventingthe necessary UV exposure. Pre-filtering is a must on all UV applications to effectively estroy micro organisms to a 99.9% kill rate.
 
How UV Water Purifiers work
Ultraviolet (UV) light is invisible and is emitted by different light sources, including the sun. At certain intensities, UV light emits enough radiation to kill the DNA in bacteria and other microorganisms. An ultraviolet water purification system typically consists of a UV light source with an output of around 254 nanometers which produces radiation of a significantly greater intensity than the radiation produced by sunlight.
 The UV light source is mounted in front of a flow chamber through which water passes. The water is exposed to the UV light source as it passes through the chamber. Any harmful microbes and bacteria that are present in the water are rendered sterile by the exposure to the germicidal radiation.
Aquiculture Water Disinfection Low Pressure UV Water Purifier
UV radiation is so effective that it can eliminate up to 99.99% of bacteria and viruses, including those associated with water-borne illnesses such as Typhoid, Gastroenteritis, Hepatitis, Flu and Cholera. UV water purification can be used to treat water whether it's from a municipal water supply, a drinking-water well, lake or a spring.

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.

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.

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.
