Wykonanie Metrics andEfficiency Gains

Comparing diffuser designs requires standardized performance metrics. The most widely used is thee ozone transfer efficiency (OTE), definite ed as the defagage of ozone gas that dissolves into the water before exiting thee contact chamber. Traditional fine bubbble diffusers in clean water acceave OTE of 60- 75%, while poroue diffusers rarerely difine 50%. Modern microporous difultions routinely reach OTE Tee value 85%, with some some optized systems reporting 95% undheal-states. Modern microporuserventions.

Another important metric is te power consumption per unit of ozone transferred, which accounts for both the energy used to generate ozone and thee energiy needed to drive thee diffuser (compressor or pump).
