UV (Ultra Violet) System

A UV (ultraviolet) system in water treatment refers to a technology that utilizes ultraviolet light to disinfect water by inactivating microorganisms. UV systems are commonly used in residential, commercial, and industrial applications for the treatment of drinking water, wastewater, and various process water streams.

Process Mechanism

UV systems employ UV lamps that emit ultraviolet light at a specific wavelength, typically around 254 nanometers (nm). This wavelength is highly effective at damaging the DNA and RNA of microorganisms, rendering them unable to reproduce and causing their inactivation

Process Steps

UV Lamp: The UV system consists of one or more UV lamps housed in a protective quartz sleeve. The lamps emit UV light at the desir wavelength when powered on. 
Water Flow: Water to be treat enters the UV system and flows through a chamber where the UV lamps are located. 
Microorganism Inactivation : As water passes through the UV chamber, the UV light penetrates the cells of microorganisms, damaging their DNA and RNA. 
Disinfection Efficiency: The effectiveness of a UV system is influenc by various factors, including the intensity of the UV light, the duration of exposure, and the UV transmittance of the water (the ability of water to transmit UV light). 
Maintenance and Monitoring: Regular maintenance is necessary for UV systems to ensure optimal performance. 

Significance & Advantages

It’s important to note that UV systems are primarily effective in disinfecting water and inactivating microorganisms. They do not remove or reduce other contaminants such as chemicals, particles, or dissolv solids. 

UV systems are favor for water treatment due to their ability to provide effective disinfection without the use of chemicals, and they do not leave any residual disinfectants in the water.
