Abstract:

Passaic Valley Water Commission (PVWC) is a publicly owned water purveyor centrally located in northeastern New Jersey. The Commission is owned by the cities of Paterson, Passaic and Clifton and serves 21 wholesale customers in Passaic, Bergen, Essex, Hudson and Morris Counties. PVWC supplies water to an equivalent population of 800,000 people with an average demand of approximately 88 million gallons per day (MGD). The demand is met through the production of finished water at the Little Falls Water Treatment Plant (LFWTP), owned by PVWC, supplemented by finished water provided from the North Jersey District Water Supply Commission.

PVWC recently completed an upgrade of the LFWTP that included the installation of an intermediate ozonation process for primary disinfection. This paper presents an overview of the upgraded water treatment process with an emphasis on the ozonation process and improvements to water quality.
