#aeration
- Aerate — To introduce fresh air into a room, an enclosed environment, or a technical system through ventilation, opening windows, or mechanical means; to subject a body, liquid, or soil to the action of atmospheric oxygen in order to improve its structural properties or to eliminate stale gases.
- Aeration — The act of aerating and its result; a physical, mechanical, or biological process through which a space, a liquid (such as wastewater in treatment plants), or a solid (such as agricultural soil) is enriched with air or atmospheric oxygen to stimulate oxidative processes, eliminate parasitic gases, and improve structural quality.
- Aeration — The natural or artificial process of air penetration and circulation inside a porous structure, soil, or liquid medium; the state of ventilation of a space. In geology and agronomy, it specifically refers to the gaseous exchange between the earth's atmosphere and soil pores, vital for the respiration of underground organisms.
- Aeration tank — A large basin, reservoir, or industrial technical installation used in wastewater treatment plants for their aerobic biological treatment. Its structural operation relies on the continuous and forced insufflation of air (oxygenation) into the liquid mass, a process that stimulates the growth of microorganisms in the active sludge which decompose polluting organic substances.
- Loosening — The act of loosening and its result; transforming a compact layer of material into a porous, loose, soft, and aerated structure. In agrotechnics, it represents a crucial seedbed preparation step; in pastry making, it denotes structural expansion.
