The AERO small wastewater treatment plant operates with the SBR-process, which has been proven for years and in which the wastewater is treated in cycles. What is new, however, is that feeding and the previously separate sludge storage as a process stage are no longer required. Instead, the sludge is also aerated and degraded. This significantly reduces the sludge volume, therefore, the sludge does not have to be removed frequently. Operating costs are reduced!
The wastewater flows through pipes into the AERO SBR small wastewater treatment plant.
Both the wastewater and the sludge are aerated. Via energy optimized membranes and the flow-optimized compressed air distribution system Airstep, the atmospheric oxygen is supplied to the bacteria with small air bubbles. Due to the resulting currents, an optimal mixing with a high cleaning performance takes place. In the AERO small wastewater treatment plant, aeration prevents the formation of digester gases and thus also hydrogen sulfide. Hence, corrosion with hydrogen sulfide from digestion processes cannot occur. This is more beneficial when retrofitting existing concrete tanks, resulting in less odor nuisance and longer service life of your concrete tank.
After the biological cleaning by bacteria is completed, the so-called settling phase takes place. In this settling phase, the cleaned wastewater separates from the biological sludge.
Cleaning of the airlift with ALC®
Shortly after the start of the settling phase, a zone with clear purified wastewater forms in the upper area. Now the ALC® process starts. Via a second airlift, cleaned wastewater is conveyed through the piping system of the airlift for the clear water removal. This removes the sludge particles deposited in the piping system during the cleaning process, and thus cleans the pipe system. As a result, fewer sludge particles end up in the outlet of the small wastewater treatment plant.
Clear water removal
After completion of the settling phase, the clear water removal is carried out. The clear treated wastewater is discharged from the upper area by a wear-free airlift into the infiltration or a stream.
