Aeration of Water

Aeration of Water

 

the saturation of water with oxygen from the air. Water is aerated in waterworks to remove iron hydroxides, free carbonic acid, and hydrogen sulfide from the water, thus substantially improving its quality; and in biological treatment plants for sewage (in aeration tanks, aerofilters, and biofilters) to provide for the activity of microorganisms (aerobic bacteria) that perform a mineralization process on the organic substances and other contaminants in the sewage.

The nocturnal aeration of water is the most common regimen of water aeration used in aquaculture.
The present study has assessed the benefits of the association between nocturnal and diurnal aeration of water on Nile tilapia's culture tanks, in regard to their water and soil quality, as well as to the fish growth performance.
As expected, the nocturnal aeration of water has avoided the decrease of D[O.sub.2] in water over the experimental period.
The results on Figure 2 suggest that the diurnal aeration of water removes more ammonia than nocturnal aeration.
The nocturnal aeration of water is prone to remove significant amounts of C[O.sub.2] from the water because the highest levels of C[O.sub.2] occur overnight (Abbink et al., 2012).
In these systems, the mechanical aeration of water is indispensable for maintaining adequate concentrations of dissolved oxygen in water.
In addition to the use of nocturnal aeration of water, which is already a consolidated management among farmers, new strategies should be sought to control water quality and obtain better productive results in intensive aquaculture systems.
The mechanical aeration of water started off from the third experimental week until the end of the experiment.
The nocturnal aeration of water is a more efficient management than the afternoon aeration in removing C[O.sub.2] from the water because, unlike what happens at night, there is little or even no C[O.sub.2] in the water during the afternoon (Cavalcante, Poliato, Ribeiro, Magalhaes, & Sa, 2009).
Aeration of water to promote the release of radon is very effective and is one of the more affordable water treatment technologies available.
. Reduce aeration of water surrounding pens to discourage algae growth.
shall perform hypolimnetic aeration of waters deeper than 16 ft.
