Over millions of years, algae and bacteria have developed an intricate relationship where the by-products of one group are the inputs for the other.
Algae grow on rotating wheels, using light, CO2 and nutrients. Algae produce oxygen, consume carbon-dioxide, and generate polysaccharides (sugars). Bacteria consume the oxygen and sugars and produce carbon dioxide – completing the cycle.
When subjected to light the algal biofilms become saturated with oxygen. When combined with wheel rotation, high dissolved oxygen (DO) levels enhance BOD reduction and nitrification.
A small air blower generates bubbles that lift and slowly rotate the buoyant Algaewheels.
