Wastewater treatment by IFAS method
In the purification package
Wastewater from office buildings is treated using the IFAS method, which is a secondary wastewater treatment method. These IFAS wastewater treatment systems consist of a series of absorbent filters and biological treatment sections and rotating biological contactors.
This system in the package
Wastewater treatment of office buildings uses a combination of activated sludge system with growth
It is suspended and fixed. Activated sludge adheres and grows on a substrate of different materials called media. Their adherent growth is considered as fixed substrate and their growth on top of each other without connecting to the media is considered as suspended part.
These media are made in two ways, one model is large media that cannot be moved, and the other model is small media and can be suspended on the surface of the sewage. The advantage of small media is its very high contact surface. On the other hand, the suspended growth of sludge also increases the contact surface of the entire wastewater with sludge, which leads to more even treatment.
Use of small media
It has another great advantage, which is that less space and a smaller tank are needed for the wastewater treatment packages of office buildings. Due to the lack of space in the buildings
This option is also very suitable for administration.
