How Nanobubbles help Mitigate Blue Green Algae in Reservoir or Stormwater Ponds

A. Prevention and Suppression of Excessive Algae Growth with Air or Oxygen Nanobubbles
 

Oxygen or Air nanobubbles are not primarily an algaecide.

Their strongest role is to improve the pond's oxygen and redox conditions particularly the bottom sediments:

Oxygen nanobubbles → higher DO (dissolved Oxygen) → more aerobic sediment → less internal P release → healthier microbial decomposition → less nutrient available for algae growth

This can be particularly valuable in a pond with organic-rich bottom sludge.

B. Fast Algae Removal out of a Pond having serious algae growth by Ozone Nanobubbles

Ozone nanobubbles → Contact with algae → Oxidative damage → Cell disruption 

→ Reduced Algae biomass reduction → Improved Water clarity

If the farm does have spaces to lay down a geomembrain lined pond or large reservoir tanks to keep enough supply for daily usage, a Foam Fractionator (a so-called Protein Skimmer) run with Ozone Nanobubbles can help clean up irrigation water out of excessive algae content and provide cleanwater for irrigation purpose.
