Description
1. UV DISINFECTION SOLUTION Disinfection is the important step in water treatment. Using UV ray is the safe and reliable method, besides that chemicals are not needed but it is still highly effective. WHY CAN UV RAY DISINFECT UV Ray (called ultraviolet ray) is the electromagnetic radiation with a wavelength is shorter than visible light. UV rays can be divided into different ranges, with short-wavelength UV rays (UVCs) considered "germicidal UV".UVC radiation with a long wavelength 240 - 280 nm is able to penetrate the cell membrane of microorganism, attack directly and destroy genetic information contained in the cell's DNA. This causes microorganisms can not act, lose their ability to reproduce and thereby become unable to infect.
At wavelength 254 nm, UV rays have ability to inactive microorganism effectively
Cell after being affected by UV rays
ADVANTAGES OF UV DISINFECTION + The disinfection process is effective and safe without using chemicals. + Does not create unwanted toxic byproducts in water. + Does not change the chemical properties of water, does not affect the taste of water. + Efficiency of disinfection is not affected by the pH value in water. + Low investment cost, operation is effective with high reliability. WHAT DO WE NOTE WHEN CHOOSING UV DISINFECTION SOLUTION?+ With different species of microorganisms, level of sensitivity to UVC radiation is also different because of the membrane structure of that microorganism. Therefore, it is should considerated choosing the necessary UV dose that can inactive the microorganism species that the plant is facing. + Metallic ions and organic acids in water have the ability to absorb radiation of UVC rays, hence effectiveness of UVC light transmission is decreased even we feel water is very clean. + Turbidity of water affects strong the effectiveness of UV light transmission. When the turbidity of water increases, much suspended solid in the water will scatter, absorb UV light, therefore effectiveness of UV disinfection is decreased. 2. UV EQUIPMENT - ULTRAAQUA _ ĐAN MẠCH ULTRAAQUA UV MANUFACTURER + ULTRAAQUA UV – was founded by Danish water treatment scientists in 1996. It is a recognized and well-established research-based manufacturer of high quality UV-disinfection systems for both municipal and industrial water treatment applications. + ULTRAAQUA UV – the success has resulted in the installation of large scale UV-systems in more than 100 different countries worldwide. + ULTRAAQUA UV – allocates many resources to research and development activities. We have close cooperation with several universities and R&D groups in different countries. These activities ensure that we can support our customers with cutting-edge knowledge and that we constantly gather information about our products from hands-on experiences in very diverse environments. + ULTRAAQUA UV – product range covers all typical applications such as disinfection of drinking water, wastewater, industrial wastewater. UV DISINFECTION TECHNOLOGY OF ULTRAAQUA MANUFACTURER The UV technology is both the oldest and one of the very latest technologies used to disinfect fluids. The method is based on the natural disinfectant action of the sun’s rays. UV lamps imitate the disinfecting rays of the sun. ULTRAAQUA UV systems produce the same ultraviolet germicidal rays, just thousands of times stronger. No bacteria, viruses, moulds or their spores can withstand this treatment. The reaction time between the UV irradiation and the organism to be killed is very short and does not create any by-products at all. The water quality, both physical and chemical, remains identical before and after treatment using the UV technique. The UV disinfection can therefore take place at any conceivable and necessary place in a system. ADVANTAGES OF UV ULTRAAQUA DISINFECTION:
- Guaranteed 16 000 hours lamp lifetime. - Save up to 22% in operational costs. - Automatic operation – optimized power consumption. - 4,3” multicolor touch display as standard in all multi-lamp UV systems – easy and simple to control. - 1" blue LED lamp status indicator in the control cabinet – easy to see the system status. - Service work include quartz sleeve and UV lamp replacement are done without the need of any tools - Corrosion-resistant electropolished AISI 316L construction. - Optional advanced auto wiping system – keeps quartz sleeves clean. - Long time ULTRAAQUA product warranty from start-up – Proven design. UV ULTRAAQUA DISINFECTION FOR WASTEWATER In order to protect the natural environment (rivers, lakes, beaches, coastal areas) increasingly stricter regulations have been implemented to limit release of pathogenic microorganisms originating from domestic wastewater. Therefore, many wastewater utilities have adopted ultraviolet (UV) as the most appropriate treatment option as opposed to chemical disinfection. UV disinfection of municipal wastewater is the only cost-effective disinfection alternative that does not have the potential to create or release carcinogenic by-products into the environment. In addition, UV is an effective disinfectant for chlorine-resistant protozoa like Cryptosporidium and Giardia. LINE UV DISINFECTION + ULTRAAQUA’s SS closed reactor series are built from high-grade AISI 316L steel are suitable for most water disinfection applications. + UV sensor and automatic mechanical cleaning systems are available. The three standard series 220 SS, 350 SS and 440 SS and the ÖNORM SSV Validated Series cover a large variety of flows and doses.
Advantages of line UV disinfection - Corrosion-resistant electropolished stainless steel AISI 316L construction; - Simple installation, operation and maintenance; - Improved energy efficiency for clear water due to internal reflection of UV light; - Operating pressure up to 10 bar; - No tools needed for regular maintenance; - Available with standard or advanced controls.
OPEN CHANNEL UV DISINFECTION SYSTEM + ULTRAAQUA open channel UV system series apply for wastewater for municipalities and industries. + ULTRAAQUA open channel UV system series offers environmentally friendly and chemical-free disinfection solutions. + Open channel systems are available for vertical, inclined and wall-mounted installations – making it a perfect solution for retrofit installation into existing chlorine contact tanks. + UV Lamp banks are based on modular design and can be expanded to treat almost any flow. The SS/PP channel series is versatile and will fit into a variety of channel depths and widths. Advantages of open channel UV system - Modular design and control system; - UV systems can be controlled remotely via ULTRAAQUA UV central PLC system; - ULTRAAQUA unique UV system design allows up to 30 cm inch variation in water level; - Regular maintenance tasks can be performed while the UV system is operational; - The design technology for Open Channel UV systems with hygienic isolated top compartment allows for easy access to all UV lamps; - Polypropylene or electropolished stainless steel AISI 316l construction; - Simple installation, operation and maintenance; - Vertically installed lamps, accessible during operation and no submerged electrical components; - No tools needed for maintenance; - Continuous lamp performance / lifetime monitoring; - Optional water level control and UVT sensor; - High level of customization – to fit in any channel dimenstion; - Automatic wiper system.
