Urban Wastewater Disinfection Equipment UV Water Sterilizer
Specification:
Ultra violet radiation is natural source of purification.
Ultra violet radiation band of invisible light in the electromagnetic spectrum, in the range of 200 - 400 nm wavelengths.
The U.V. wavelength of 253.7 nm possesses the greatest germicidal effectiveness, which Penetrate the microbial cell membrane to destroy the DNA molecule thus preventing cell Replication.
U.V. is used to provide Bacterial Disinfection in water. It does not change the Physical or Chemical Characteristics in water. U.V. provides disinfection On Contact. It does not have any residual properties left in treated water.
Special High Germicidal Lamps produce high U.V. output in 254 nm range.
There are no know micro organisms resistant to U,V,
U.V. water purification is preferred the world over because it is the simplest & most practical means of destroying micro organisms in water.
What is Ultraviolet Light Disinfection?
Ultraviolet disinfection is a means of killing or rendering harmless microorganisms in a dedicated environment. These microorganisms can range from bacteria and viruses to algae and protozoa. UV disinfection is used in air and water purification, sewage treatment protection of food and beverages, and many other disinfection and sterilization applications. A major advantage of UV treatment is that it is capable of disinfecting water faster than chlorine without cumbersome retention tanks and harmful chemicals. UV treatment systems are also extremely cost efficient!
Ultraviolet disinfection systems are mysterious to many people - how can "light" kill bacteria? But the truth is it can. Ultraviolet (UV) technology has been around for 50 years, and its effectiveness has been well documented both scientifically and commercially. It is nature's own disinfection/purification method. With consumers becoming more concerned about chlorine and other chemical contamination of drinking water, more dealers are prescribing the ultraviolet solution suitable for both small flow residential applications as well as large flow commercial projects.
What are the Advantages of UV Disinfection?
Advantages of UV disinfection
1. High disinfection efficiency
UV light with a wavelength of 254 nm is very effective against pathogenic microorganisms,including bacteria, viruses, and protozoa. It also is capable of inactivating Giardia and Cryptosporidium, which are not destroyed by conventional chlorine disinfection.
2. Short treatment time
It takes only a few seconds to kill or inactivate pathogens with at least 99.99% efficiency.
3. Optimal cost
Only 1 kWh is needed to disinfect 800 tons or 30,000 cubic feet of water.
4. Safety
Physical, chemical-free process, n . Doesn't affect the initial pH level, change chemical composition, taste or odor of water.
5. Convenient installation and operation
Simple installation and maintenance. Continuous operation. Minimum moving parts. Small footprint. Custom design available.
6. Large capacity
UV systems can treat 1-100 (264-26,400 gpm) of water per minute. Flowrate is almost not affected by water temperature.
7. Automatic control
Fully automatic PLC control. Customized system set up. Emergency alarm and shutdown. Remote control (optional).
8. Reliability
Our engineers have more than 20 years of experience in water treatment.We incorporate their know-how patented technologies to the UV systems,along with brand name key components (lamps, ballast).
How does UV Disinfection Work?
Ultraviolet is one energy region of the electromagnetic spectrum, which lies between the x-ray region and the visible region. UV itself lies in the ranges of 200 nanometers (nm) to 390 nanometers (nm). Optimum UV germicidal action occurs at 260 nm.
Since natural germicidal UV from the sun is screened out by the earth's atmosphere, we must look to alternative means of producing UV light. This is accomplished through the conversion of electrical energy in a low pressure mercury vapor "hard glass" quartz lamp. Electrons flow through the ionized mercury vapor between the electrodes of the lamp, which then creates UV light.
As UV light penetrates through the cell wall and cytoplasmic membrane, it causes a molecular rearrangement of the microorganism's DNA, which prevents it from reproducing. If the cell cannot reproduce, it is considered dead.
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.

Frequently Asked Questions About Ultraviolet (UV) Purification
1. What is UV?
Ultraviolet (UV) light is at the invisible, violet end of the light spectrum. Even though we can't see UV light, we are exposed to UV rays from all light sources, including the sun.
2. How does ultraviolet light purify water?
UV-C rays penetrate the cells of harmful bacteria and viruses in our drinking water, destroying their ability to reproduce. Without this ability, these organisms die and no longer pose a health threat. It is a simple but very effective process, with the system destroying 99.99% of harmful microorganisms.
3. Why not use chlorine instead?
Chlorine changes the taste and odor of water. Chlorinating also produces harmful by-products called Trihalomethanes (THMs) which are linked to incidence of cancer.
4. Does a UV system use a lot of energy?
No, the UV unit will use about the same amount of energy as a 60 watt light bulb. It is a cost effective, natural way to increase water quality.
5. Why do UV purifiers require sediment pre-filtration?
UV systems require pre-filtration to maintain effectiveness as sediment and other contaminants in the water can create a "shadow" which prevents the UV rays from reaching and disinfecting the harmful microorganisms.
6. How often does the UV light bulb (lamp) need to be replaced?
It is essential that you change your UV lamp annually. The ability of the lamp to emit UV light decreases over one year in operation. Remember - UV light is invisible! Even though the lamp is still glowing after one year, there might not be enough UV light reaching your water to be effective.
7. How often do your need to replace the sleeve?
The sleeve doesn't need to be replaced unless it is broken, but it will need to be cleaned several times a year in order to keep the bulb effective in delivering high water quality.
