This paper presents three projects that have been implemented in Ohio with the MBR activated sludge technology. It includes one plant that is the largest constructed in North American and one of the first in Ohio using BNR treatment to achieve total nitrogen limits. The presentation provides the plant design criteria, process operation, control, f...

The paper and will explain the design, optimization methodology, and cost efficiencies of the City of Canton Water Reclamation Facility (WRF) ,the largest membrane bioreactor activated sludge (MBR) process in North America. Flows, unit process and MBR process components and trains, associated support systems, levels of redundancy, chemicals syste...

This paper includes the unique challenges and creative solutions for doubling the hydraulic capacity of a conventional activated sludge plant by retrofitting a four stage membrane bioreactor process within the existing footprint. Moreover, to meet future more stringent nutrient removal requirements to protect the Chesapeake Bay, the new facility ca...
