The New Jersey Department of Environmental Protection is pleased to announce the release of the Wet Weather Flow Treatment and Disinfection Demonstration Project (WWDDP) Report. The complete report is available at: nj.gov/dep/dwq/cso-wet.htm.

This project was conducted over a two-year period at the Oak Street facility in Bayonne, NJ which receives combined sewage from Bayonne City. The primary focus of the WWDDP was to verify the performance of selected technologies to treat combined sewer overflow (CSO discharges) for solids removal and disinfection under field conditions suitable for remote satellite locations. The WWDDP included high rate solids removal and disinfection where six (6) technologies were tested. The three (3) solids removal technologies included high rate solids removal (i.e. vortex and plate settler units) and enhanced high rate solids treatment (i.e. compressed media filter). Additionally, three (3) types of disinfection units were included; chemical disinfection (i.e. Peracetic acid, PAA), and ultraviolet (UV) disinfection, low and medium pressure.
