Evoqua Water Technologies will replace eight Rotating Biological Contactors (RBCs) that have reached the end of their useful life at the Cape May Wastewater Treatment Facility in New Jersey.

The Authority wanted to replace existing Lyco brand RBC units, originally installed over 35 years ago, with a solution that would provide Soluble Biochemical Oxygen Demand (SBOD) removal.  The Authority has used the RBC process for many years at its four wastewater treatment facilities as it can accommodate significant increases in flow and load during the summer tourist season.

Evoqua’s Envirex Series 400 RBC systems were selected because of their large media surface, flexible design, and reliable performance history. Evoqua, with their sales partner, Iron Horse Environmental, will supply eight RBC units arranged in two trains with four units in each series. Each RBC unit features a heavy-duty shaft designed for superior fatigue resistance, flexible treatment with two media densities, and a hot-dipped galvanised corrosion-resistant media support system.  

Installation of the first train will occur in late Spring 2021, with the remaining units late in 2021.
