UV LEDs for Municipal Drinking Water
Municipal drinking water applications cover a large variety of systems, from small city treatment plants to large municipalities.
UV-C for Treating Drinking Water
Each facility has unique challenges they face for their disinfection needs. While most use chlorine for drinking water treatment, some find the added benefits of UV disinfection necessary to cover a wider variety of pathogen.
UV is typically used as a last step for the treatment process as it requires relatively high Ultraviolet transmittance (UVT) and can treat pathogens beyond typical chlorine treatment, such as Cryptosporidium and Giardia.
UV LEDs in Municipal Water Treatment
While conventional UV systems have been to leader in municipal systems, UV-C LEDs have been gaining headway in their capabilities, including the flowrates they can treat. Several UV LED manufacturers have designed systems using UV LEDs which promote UV disinfection without the use of mercury.
AquiSense Technologies designed and manufactured the PearlAqua Tera, the first municipal UV LED system in North America. The PearlAqua Tera is being installed in the Las Vegas Valley Water District in Q1 of 2022.
