Ultraviolet Systems
Disinfection of water with ultraviolet (UV) is a method that uses ultraviolet light to remove harmful microorganisms from water.
UV disinfection uses short-wavelength UV-C light that damages the DNA and RNA of microorganisms. This light effectively inactivates microorganisms by preventing them from multiplying and surviving.
Working Principle of UV Disinfection
UV-C Ray (200-280 nm): UV light, especially at a wavelength of 254 nm, disrupts the DNA structure of pathogens such as bacteria, viruses, fungi and molds.
When microorganisms are exposed to UV light, their DNA or RNA chains are broken, preventing the cells from multiplying, thus ensuring the cleanliness of the water or surface.
Advantages of UV Disinfection
No chemicals are used: Since no chemicals are used in this method, it is an environmentally friendly disinfection method.
Instant effect: UV light quickly inactivates microorganisms. Does not leave any residue: Unlike chemical disinfection, it does not leave any chemical residue on water or surfaces.
UV (ultraviolet) disinfection systems usually consist of several main components. These parts ensure the correct operation of the system and effective disinfection. The basic components of the system are:
1-UV Lamp (UV-C Lamp): It is the most important part of the UV system. It disinfects water by producing UV-C light. It typically emits UV-C light at a wavelength of 254 nm. Lamps are usually made of quartz glass and have a certain lifespan. This lifespan is usually around 9,000 hours.
2-Quartz Sleeve (Protective Coating): It is a protective tube around the UV lamp. The quartz sleeve is designed to allow UV light to pass through, but prevents water from directly contacting the lamp. This sleeve extends the life of the UV lamp and simplifies maintenance.
3-Reactor Body: This is the part where the UV lamp is placed and where water or air passes through. The reactor body is usually made of stainless steel and allows the UV light to reach the water effectively. The design of the body is optimized to ensure that the water is exposed to the UV light at the right speed and amount.
4-Control Panel: It is an electronic panel that is used to turn the UV lamp on and off, monitor the system's operating time and detect fault conditions. Some systems also include a monitor to monitor the lamp's life and the power of the UV light. It controls the emitted C rays and warns the user in low light conditions.
5-Sensors (Optional): Some systems have sensors to measure the power and efficiency of the UV light. These sensors can be used to visually or audibly control how much UV the lamp is receiving when there is a fault in the system or when the lamp life is over. These components come together to ensure that the UV disinfection system operates effectively and safely.
6-Güç Kaynağı:UV lambasına elektrik sağlayan bir ünitedir. Sistemin güvenli ve sürekli çalışmasını sağlamak için stabilize bir elektrik kaynağı gereklidir.Elektronik çalışma saati, Bu özellik, UV cihazının ne kadar süre çalıştığını takip etmeye olanak tanır. Cihazın bakım gereksinimlerini belirlemek için kullanışlıdır.
7-Sesli Arıza bildirimi(opsiyonel), Cihazda bir arıza oluştuğunda sesli uyarı verebilecek bir sistem mevcuttur.
8-Alarm Röle Çıkışı(opsiyonel) Cihazın bir alarm durumu oluştuğunda bir dış sistemle bağlantı kurabilmesi için kullanılan röle çıkışıdır.Otomasyon sistemine aktarım için opsiyonel olarak kullanılır.
9-Akış Regülatörü veya Debimetre( opsiyonel )Sistemdeki suyun debisini (akış hızını) kontrol eder. UV ışığına maruz kalma süresi dezenfeksiyonun etkisi açısından kritik olduğu için, suyun sistemden doğru hızda geçmesi sağlanır.
Her parça, sistemin performansını optimize etmek ve uzun ömürlü olmasını sağlamak için belirli bir işleve sahiptir.
