Hello Iman your post ...

Hello Iman your post presents some small imperfections.

Activated sludge????

Treatment?????

Extended ventilation???

There is no treatment of sludge by prolonged aeration. Prolonged aeration or short aeration is the aeration mechanism that determines the activation of the sludge.

I explain

As soon as the effluent arrives at the management terminal site, it passes through an aeration bin. This is an endless screw that injects air to the bottom of the aeration bin.

Is there a treatment? No, it is only a matter of killing the process of digestion of the effluent. At the base of the design of the stations the initiation of the digestion process of the effluent fissurait the concrete of the construction of the bins. By aerating the tray by an endless screw, the process of digestion is killed.

To label this process, the technicians had the idea of upgrading it in a form-biological-of a possible treatment of the effluent, which is not at all the case.

 

Activated sludge

All suspended matter in the effluent is transformed into mud as soon as it loses its characteristics-biological-often from:

-Oxygen deficiency

-Chemical molecules

It is often actually mud that arrives at the sewage management site. This mud has nothing more-biological-, it is a dead element, inert. For this reason, globally, management stations produce more than 45 million tonnes of muddy waste annually.

The mud is indestructible-biologically-speaking.

Before being mud it was organic matter mostly of fecal matter bathing in a liquid impregnated with urine. A urine that in contact with oxygen transforms urea into ammonia.

All the biochemical components of the urine, added to the chemical molecules of detergent products and brewed by the aeration tray make a highly toxic liquid.

The activated mud is therefore only mud brewed by an endless screw that does not bring anything other than increase the toxicity of the medium by the presence of a high dose of oxygen.

 

The treatment is ghostly since in spite of several stages of the station's device there is as much mud at the exit as the one that entered it.

Only micro organisms can reduce, see remove the suspended organic matter but in the sludge they died. Sewage sludge contains more than 8% of dead bacteria.

A heresy since naturally a dead bacterium does not exist.

 

The prolonged action of the sludge aeration system is useless as long as the liquid has become inert neutral. Aerating it for hours will increase the energy cost of wastewater management at the terminal site.
