Concentration before separation

Treat the phosphorus—not the whole lake.

Surface-water phosphorus is often extremely dilute. Moving enormous quantities of ordinary lake water can therefore produce little meaningful nutrient export. Cascade finds where phosphorus is concentrated first, then engineers treatment around that stream.

Concentration before separation

Higher influent phosphorus concentration improves the potential economics of every downstream treatment technology.

  • Deep hypolimnetic water
  • Sediment-water interface
  • Nutrient-rich tributaries
  • Stormwater and runoff events
A cross-section of a lake shows nutrient-rich deep water flowing to a shore-based capture unit. Treated water returns to the lake while captured phosphorus is exported into a separate collection vessel.
Target concentrated phosphorus, capture it externally, and measure what permanently leaves.

A flexible treatment train

Technology agnostic by design

Targeted water enters a modular capture platform with three interchangeable treatment modules. Treated water returns to the lake while captured phosphorus leaves the system.
A common hydraulic architecture can evaluate multiple capture technologies without redefining the entire field system.

The learning system

Every deployment should make the next one better

Cascade’s long-term advantage is not one filter.

It is the dataset connecting lake characteristics → phosphorus concentration → treatment configuration → operating cost → phosphorus export → ecological response.

Measured flow multiplied by the difference between influent and effluent phosphorus concentration equals the mass of phosphorus exported from the system.
The north-star metric pairs measured phosphorus mass export with improvement in lake condition.
