Aeration for food and dairy effluent
Food processing and dairy effluent carries a high organic load that changes with production. Floating aerators add oxygen to effluent lagoons and balancing tanks, keep solids moving and help control odour, and more units can be added for seasonal peaks.

Why does food and dairy effluent need aeration?
Milk, whey, wash water and process residues are rich in organic matter. Without enough oxygen a lagoon turns septic, which raises odour and makes it harder to meet discharge limits.
What helps with changing production loads?
- Floating units that follow the lagoon level
- Extra or hire units for seasonal peaks
- Aspirating aerator mixers where mixing matters as much as oxygen
- Low aerosol units near roads and neighbours
What should I send with an enquiry?
- Lagoon or tank size and depth
- Daily flow and, if known, BOD or COD
- When production peaks
- Your licence limits
Frequently asked questions
Do aerators help with lagoon odour?
Keeping a lagoon aerobic is the main way to avoid the septic conditions that cause odour, and the splashing of surface aerators also strips dissolved gases such as hydrogen sulfide.
