UV water sterilizer
Potabilization of water Treatment
UV water sterilizer (Ultraviolet sterilizer) refers to a device that uses an ultraviolet mercury lamp as a light source and uses 253.7nm ultraviolet rays radiated by mercury vapor in the tube as the main spectral line to sterilize drinking water (abbreviated as sterilizer).
UV disinfection has no dead ends, good light emission conditions, low energy consumption, equipment installation and removal flexibility, no secondary pollution, UV disinfection is relatively chlorine sterilization, he has no need to add chemicals, no secondary pollution, no The mixing equipment greatly reduces the operating cost of the equipment. If it is drinking water, the ultraviolet sterilizer is safe and will not adversely affect the human body due to the excessive amount of medicine. Compared with the ozone sterilizer, the ultraviolet sterilizer has the advantages of low energy consumption, no large mixer, no fishy smell, etc., which not only has a good look and feel, but also reduces operating costs.
Ultraviolet sterilizer is widely used
UV sterilizer has high value in water treatment. It destroys and changes the DNA structure of microorganisms through the irradiation of ultraviolet light, so that the bacteria die immediately or cannot reproduce their offspring to achieve the purpose of sterilization. It is ZXB ultraviolet that really has the bactericidal effect , because the C-band ultraviolet is easily absorbed by the organism's DNA, especially the ultraviolet around 253.7nm. Ultraviolet sterilizer is a purely physical disinfection method. It has the advantages of simple and convenient, broad-spectrum and high-efficiency, no secondary pollution, easy management and automation. With the introduction of various new-designed ultraviolet lamps, the application range of ultraviolet sterilization has also continued Expanding.

Principle for UV sterilization
All forms of life known on the earth exist on the basis of DNA and RNA for reproduction and existence. DNA and RNA are both composed of 4 kinds of chemical substance units.
A--Adenine
T--Thymine
C--Cytosine
G--Guanine (the basic component for the nucleic acid)
In time of cell reproduction, the long chains inside DNA are opened when Unit A in each chain will look for and connect with Unit T. Each long chain can reproduce an identical chain to the chain freshly split, restore the complete DNA before splitting and serve as the foundation for the new-borne cells. However, the ultraviolet at a wave length of 240-270nm is able to break the capacity of DNA to produced protein and reproduction. Once the DNA and RNA of bacteria and viruses are damaged, their capacity to produce protein and reproduction are both lost. As the bacteria and viruses usually have a very short life cycle, those will soon perish that cannot reproduce.
The effective of UV sterilization is often expressed in killing ratio, e.g., 99.9%. Namely, 99.9% of the original bacteria have been killed and only 0.1% exists, or, 1/1 000 has survived. As 1000 is the 3 in 103 or in log, it is habitually to express the killing ratio with 310g. The killing ratio of ultraviolet depends on two factors: 1, ultraviolet intensity (I); and 2, irradiation time (T).
Advantages of Modern UV C Disinfection)
The UV C Disinfection Technology has been widely accepted by the world for its superior effect in disinfection on cell viruses and other Factors to be Considered Liquid chlorine disinfection Chlorine dioxide disinfection Ozone disinfection LW disinfection pathogenic agents. UVC water disinfection technology has the following obvious advantages.
High-efficiency sterilization
Sterilization of cell viruses with UV C is generally within one second. In comparison, the traditional UV and Cl and Ozone Methods takes 20 min to one hour to match the effect of UVC.
No secondary pollution
As the UV-c Technology can be controlled within the scope of killing the bacteria or viruses only and it is unnecessary to add any chemicals, it Operation complexity Simple to middle grade Simple to middle grade will not cause the secondary pollution to the water body and the surround environment. Meanwhile, it will not change any component of the water.
It makes continuous mass sterilization possible.
The modern UV-C disinfection equipment can work 24 hours a day and 365 days a year. Except for the general maintenance within the fixed time, the optimum operation condition is the 24-hour continuous operation.
Operation and maintenance is simple and easy and of low cost.
With the improvement of UV-C core technology, the UV-C disinfection technology is not only the means of the highest disinfection rate of all the disinfection methods but also the simplest and easiest in operation and maintenance and of the lowest cost, reaching RMB 0.004 Yuan/T of water. Therefore, cost performance ratio is the highest of all the disinfection technologies. It has the high efficiency advantage superior to other sterilization technologies but also is the lowest in cost and expenses for operation and maintenance.
Safe and Reliable Operation
In terms of the traditional sterilization technology, like the methods of using the chloride or ozone, the disinfectant itself is highly toxic, flammable and explosive. Application of these substances causes latent threat to the site operators, the surrounding environment and the nearby residents. The modern ultraviolet disinfection system, however, does not bear such potential risks.
Process flow
When preparing the pure water or high-purity water, predesalination is often conducted with the reverse osmosis units and the ion exchange process is taken for deep desalination. The ultrafiltration device is adopted to further remove the colloids, microorganisms, bacteria and mechanical particles in the water. The main process flow for preparing the pure water or high-purity water with the ultrafiltration units consists of:
Raw water Pre-Processing RO Ion exchange Ultraviolet sterilizer
Ion exchange UltrafiItration User
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) |
As a general guideline, the following are some typical UV transmission rates (UVT)
| City water supplies | 850-980‰ |
| De-ionized or Reverse Osmosis water | 950-980‰ |
| Surface waters(lakes, rivers, etc) | 700-900‰ |
| Ground water(wells) | 900-950‰ |
| Other liquids | 10-990‰ |
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).

FAQS: WATER TREATMENT USING UV AND OZONE
Why are no chemicals necessary for the water treatment of swimming pools and spas with the Ultra-Bio-Ozone™ system?
Thanks to its patented injection system, a regular ozonisation charge* replaces any chemical product, the addition of remanent is no longer necessary (usually 20-30%), in contrast to all the other methods of UV or ozone water treatment currently on the market.
What is the advantage of double Ozone and Ultraviolet treatment?
The effect combats bacteria, viruses, algae, and fungus.
Ozone kills by oxidation via rupture of the cellular membrane within a few seconds of contact.
The UV has a germ-destroying effect on the micro-organisms which inactivates them (no more reproduction) or kills them.
Having the 2 methods of treatment in the same system means the elimination of all forms of microbiological contamination.
What is ozone?
Ozone is nothing more than oxygen to which an additional atom is added.
An oxygen molecule is made up of two atoms. As it passes in front of the UV lamp at 185 Nm, the oxygen molecule (O2) splits into 2 atoms and then reforms with 3 atoms, thus ozone (O3) is created. Ozone (O3) is very unstable and will return very quickly to its original state - Oxygen (O2).
How is ozone produced?
The 2 most common methods are:
Using the ultraviolet system (the oxygen is passed in front of a UV-C lamp to 185 Nm).
Using "corona" discharge (oxygen is passed over an electric field between two metal plates).
What is the difference between ozone produced by the "UV lamp" and the "corona" system?
Both means of production are efficient. Here are the main differences:
Advantages of corona discharge: Less electricity consumption to produce the same amount of ozone.
Disadvantages of corona discharge:
- A lot of electronics; not possible to repair without the assistance of a technician.
- To produce the required quantities of ozone, the "corona" system must use dry air provided by an air drier or air from a bottle.
- The loss of ozone production can reach up to 80% in the event that very damp air is used, which completely cancels out the economy achieved by lower electricity consumption and increases the costs by the same amount as installing an air drying system.
- One detail often "overlooked" by salesmen is that the "corona" systems have a limited useful lifespan of a few thousand hours. Depending on the quality of the metal plates and materials used, it will be necessary for a professional to dismantle the apparatus.
Advantages of the UV-C Lamp:
- Main advantage, double production of the ozone effect by passing the air in front of the lamp and a germicidal effect by passing the water in front of the lamp.
- Maintenance reduced to a minimum; the lamp is changed every 10,000 hours and the quartz tube cleaned
- A system which will work for many years.
Disadvantages of the UV-C Lamp:
- Inferior production of ozone compared to the corona system, but the difference is reduced because
current UV-C lamps are much more powerful than in the past. - Bulkier apparatus.
- Higher purchase cost partly due to use of stainless steel.
How is the ozone produced injected into the water in the "U-B-O" system?
- Ozone is injected into the water using a venturi,
- Water and ozone are mixed in the contact tank
- The water mixed with ozone passes through two UV tubes with extremely powerful lamps which act to treat the bacteria, virus, fungus, and algae which would have resisted the ozone, and emerges perfectly disinfected.
What is the risk of the ozone produced being present in the water after passing through the system?
No, because our "U-B-O" system has a de-ozonisation device, which eliminates the residual ozone in the water before it leaves the system.
Is the contact time with the ozone sufficient for destroying the bacteria and the viruses present in water?
Yes, the contact time is sufficient, thanks to the Venturi, the contact tank and the lengthy processing of the ozonated water in our system.
Is it obligatory to disinfect the water in a private swimming pool?
No, disinfecting water is only obligatory for swimming pools used by the public, contrary to what certain people in certain forums would have us believe.
How can the water be lightly disinfected, for example in a swimming pool used by the public?
Very low doses of the bromine or chlorine pellets is one way of lightly disinfecting water; the quantity used must be at least 0.4mg/litre, which is 3 times lower than the recommended amount if you treat your water only using bromine or chlorine.
Running and Maintenance Costs:
Use: power consumption of the lamps.
Maintenance: replacement of the lamps every 10,000 hours for good ozone production, i.e. every 2 to 3 years on average for year-round use of the swimming pool or spa.
Clean the quartz tubes (easy to do) every 6 months, depending on the quality of the water.
* 1-4 once a week, at a convenient time when there are no bathers, for example, at night.
