Not Your Father's Water Treatment Plant
This paper describes the history of water treatment in Bozeman, Montana and the efforts that went into starting up and operating the 22 MGD Sourdough Water Treatment Plant that uses microfiltration in 2014. There is a thorough review of the challenges in training and operations and understanding of the needs of the operators....
Personnel Issues Converting to a Membrane Plant
Bozeman, MT is located in Southwest Montana and has a population of about 38,000 people and has experienced rapid growth in the last 15 years. The original water treatment plant was a direct filtration plant with multimedia filters and built in 1984 with a capacity of 10 MGD on a shoe string budget when EPA regulations were much less strict. In 199...
Lessons Learned in Three Years of Membrane Plant Operation
The City of Bozeman put a 22 MGD microfiltration plant online in March of 2014. Over the course of the last three years of operation, several lessons have been learned. It was a large change from the previous direct filtration multimedia plant that had minimal automation. The presentation will highlight several of the important lessons the City of ...
Making Data-Driven Decisions to Improve Membrane Performance
In a membrane plant you can be overwhelmed with data. Some of it useful, some of it not so useful. The key is to weed out the less then useful data so the operators can focus on the useful data. Once the data is filtered out operators can use it to make informed decisions on how to improve membrane and overall plant performance, and indicated poten...

Operating an Over Built Plant
The City of Bozeman built a 22 MGD microfiltration plant in 2014 to meet the demands of a growing city. The plant is built to basically plug and play additional treatment equipment for 36 MGD. The current demand averages 5 MGD with peak demand in the summer of just over 9 MGD. As a result of this the plant is vastly overbuilt for the current flows ...
Rethinking Membrane Plant Operations
The City of Bozeman WTP has had membranes in service for 8 years. Over the course of the last 8 years plant operators have been working to optimize and improve operations to be more efficient and sustainable. Operators have taken initiative to optimize coagulant dosages, membrane cleaning, minimize chemical usage for residuals treatment, and reduce...
