In a side-by-side trial at the same municipal plant, the Supercritical UV™ disinfection system achieved 2 to 3 log better E. coli reduction than a conventional submerged lamp system.
A municipal wastewater treatment plant serving a town of approximately 17,000 people processes both domestic wastewater and a significant volume of industrial trade waste from multiple factories. The treatment system consists of anaerobic, aerobic, and chemical treatment prior to ultraviolet disinfection.
In a direct head-to-head trial at the site, a NovoLabs™ Supercritical UV™ pilot unit was installed and operated simultaneously alongside an existing submerged lamp UV system supplied by one of the world's largest UV treatment companies. Inlet conditions prior to ultraviolet treatment were:
UVT of 30.5%
TSS of 50 g/m³
E. coli concentration of 3,890 MPN/100mL
The Supercritical UV™ system achieved 2-3 LRV better than the conventional system, in conditions that would be considered relatively straightforward for a SCUV™ system but were considered too challenging for the existing system to treat adequately.
