How does Moleaer nanobubble treatment compare to mechanical dredging?

Mechanical dredging physically removes organic and inorganic sediment from a waterbody but comes with significant drawbacks: it is 10–100x more expensive than nanobubble treatment, requires closure of the waterbody during operation, involves heavy machinery and extensive permitting, and can itself release nutrients and pollutants during excavation. Ecologically, dredging is disruptive and its benefits tend to be short-term, as it does nothing to address the underlying anoxic conditions that drive ongoing muck accumulation and nutrient release. Nanobubble treatment, by contrast, stimulates natural aerobic decomposition of muck in-place, with no heavy machinery, no waterbody closure, no need for waste disposal, and, by creating and sustaining oxygen levels at the lake bottom, slows muck accumulation over time.
