Abstract:

Summary

The completed UV disinfection facility as part of the Mangere WTP upgrade, with a maximum discharge rate of 16,500 l/s (59,400 m³/h = 376.6 MGD) and a total number of lamps close to 8,000, is one of the largest and most sophisticated wastewater UV disinfection systems in the world. Tests had shown a reduction in viral incidence by a factor of 10⁴. The design permissible bacterial concentration in the treated wastewater is a monthly average of no more than 80 faecal coliforms or 35 enterococci per 100 ml.

The UV system is now in operation for 4 years with a very successful performance record. It continues to draw attention from around the globe as “a world-class installation”.
