Cascade Aquatics Wants to Give Lakes a Way to Let Phosphorus Out
Cascade Aquatics is developing modular systems to capture and physically remove phosphorus from impaired freshwater lakes and nutrient-rich inflows.
Field notes
The project focuses on phosphorus that can remain in circulation after watershed inputs are reduced, particularly when low-oxygen conditions release it from bottom sediments. Its proposed workflow looks for concentrated water in places such as inflows or the sediment interface, treats that water outside the lake, and removes the captured residual. The initial service area is Wisconsin, Minnesota, and Michigan. The site is seeking pilot partners, but the supplied material does not show operating results or technical performance data.
