Intermittent solar aeration device
In this study we employ computational methods to investigate the influence of aeration strategies on simultaneous nitrification–denitrification processes. Specifically, we explore the impact of periodic and intermittent aeration on denitrification rates, which typically lag behind nitrification rates under identical environmental conditions. A two-dimensional deterministic … - Download [PDF]

The device operates at a power of 2 W, functioning continuously over 24 hours with an aeration duration of 12 hours. It includes …
Application of intermittent aeration in nitrogen removal process ...
With the discovery that NOB was inhibited under intermittent aeration condition, intermittent aeration has been considered an effective operational strategy for partial nitrification–denitrification process [18], [19], [20], which has gained increasing attention for low oxygen and carbon source consumption [16].A full-scale partial nitrification–denitrification …
Intermittently Decanted Extended Aeration (IDEA)
4 hours operating cycle for normal operation; 3 phases per cycle controlled by an automatic timing device: • Aeration: 2.5 h • Settling: 1.0 h • Effluent decanting: 0.5 h This process is similar to SBR process, which has eliminated a number of SBR process problems. The average biological removal efficiency in terms of BOD removal and COD removal was about 95.5% and 90%, …
Solar Pond Aerators
A more affordable solar option is called "direct drive", which will only run during the daylight hours. Like a windmill aerator that will only function with the winds are blowing, these intermittent systems are certainly better than no aeration at all. And between the two, unless you live in a really wind prone area, I would tend to lean to ...
