aeratsiooni
Aeration is the process of introducing air into liquids, slurries, or soils to raise dissolved oxygen levels and facilitate oxidative or aerobic processes. It is widely used in environmental engineering, agriculture, and product processing.
Oxygen transfer occurs primarily at the air-liquid interface and through bubbles; the rate depends on temperature,
Common methods include mechanical surface aeration (paddle wheels, propellers), diffused-air systems (air diffusers at depth), and
Applications: water and wastewater treatment (increase dissolved oxygen, support aerobic microbial digestion, reduce odors), aquaculture (improve
Benefits and considerations: improves oxygen availability and mixing; can aid pollutant degradation and odor control; drawbacks
