Big Sky Membrane Masters: A Low-Pressure Workshop
Join AMTA in Billings, MT on August 6-7, 2025 for an engaging workshop focused around low pressure systems with a dash of MBR sprinkled in. You will have the great opportunity to tour the new WTP under construction, hear from regulators, learn about retrofitting media filters to membranes, some success stories, a reuse story, and lessons learned for operators. This workshop will be the perfect opportunity to explore what Montana has to offer while obtaining membrane knowledge. The committee is wrapping up the program so stay tuned for more information.
