Glossary of Terms
We've provided a glossary of terms specific to the aeration industry as a reference for anyone visiting the site who is unfamiliar with the terminology.
- Aerobic Digestion -
A bacterial process occurring in the presence of oxygen. Under aerobic conditions, bacteria rapidly consume organic matter and convert it into carbon dioxide. Once there is a lack of organic matter, bacteria die and are used as food by other bacteria.
- Aqua Culture -
The cultivation of aquatic organisms under controlled conditions.
- BOD -
Biochemical Oxygen Demand is a chemical procedure for determining how fast biological organisms use up oxygen in a body of water.
- CAFO -
Concentrated Animal Feeding Operations
- COD -
Chemecal Oxygen Demand is a test commonly used to indirectly measure the amount of organic compounds in a body of water.
- DO -
Dissolved Oxygen is a relative measure of the amount of oxygen that is dissolved or carried in a given medium.
- Effluent -
An outflowing of waste material (as smoke, liquid industrial refuse, or sewage) discharged into the environment especially when serving as a pollutant.
- Leachate -
The liquid that drains or "leaches" from a landfill, mostly caused by precipitation.
- TKN -
Total Kjeldahl Nitrates is the sum of organic nitrogen; ammonia, NH3 and ammonium, NH4+ in biological wastewater treatment.
- Kjeldahl Method -
A method for the quantitative determination of nitrogen in chemical substances developed by Johan Kjeldahl.
- TSS -
Total Suspended Solids is a measure of particulate weight obtained by separating particles from a water sample using a filter.
- Aeration -
The process by which air is circulated through, mixed with or dissolved in a liquid or substance.
- Taeration -
The fastest and most economical way to aerate a liquid, with complete mixing and de-stratification of a vessel or body of liquid, using only a centrifugal pump, and without a mechanical, artificial or venturi air supply.
