Case Study: A Wastewater Plant Bio-Augmentation Success

By Jim Dartez, RELIANT Water Technologies

Rosethorne WWTP is located in Jefferson Parish, Louisiana, just west of New Orleans. The plant was constructed in the mid-1990s with a design capacity of 400,000 GPD. Today, the average daily flow through the plant is approximately 250,000 GPD. During Hurricane Katrina, in 2005, the plant suffered considerable damage to its mechanical infrastructure, and even after repairs, its effluent was unable to comply with regulatory discharge permit requirements since the storm.
