"Supporting the progression and demonstration of new water technologies is one of The Water Council's main objectives," said Karen Frost, Vice President of Economic Development and Innovation for The Water Council. The Proteus pilot project at MMSD's South Shore wastewater treatment plant is expected to operate from October of 2021 until March of 2022 and will be available for touring. The technology was recently featured by Global Water Intelligence as a "Primary Treatment Pioneer" for its clever use of split-bed aeration and cross-shaped media to improve wastewater treatment plant resilience and flexibility. Proteus is also much smaller compared to traditional technologies, offering the potential to shrink the physical footprint of sewage treatment infrastructure. Proteus, which provides simultaneous removal of suspended solids and digestion of organic contaminants from wastewater without the use of chemicals, handles a far greater range of flow rates compared to clarifiers or settling tanks which traditionally have filled the role of primary treatment. The agency is also interested in Proteus more broadly as an advanced primary treatment system which may be able to provide cost-effective retrofit opportunities to improve downstream treatment capacity through carbon redirection and footprint savings. For MMSD, whose Jones Island and South Shore facilities treat 150 million gallons of wastewater on a dry day but roughly 630 million gallons during a rainstorm, innovation in wet weather flow management is a long-term priority. The Proteus up-flow media filter technology is designed to increase the tolerance of wastewater treatment plants to "peak flow events" caused by rainstorms, safeguarding plant performance in the face of aging sewer systems and erratic weather patterns caused by climate change. The Proteus technology will be installed on-site for a demonstration pilot at the Milwaukee Metropolitan Sewerage District's (MMSD) South Shore Water Reclamation Facility. After a competitive selection process, Tomorrow Water's Proteus technology was chosen for TWC's 2021 Pilot Program because of its potential to benefit the Great Lakes and local wastewater treatment facilities.
