Activated Sludge Biological Plants
Biological, active sludge treatment removes pollutants present in the water to be purified by converting them into a fleecy, easily-separated bacterial suspension. Here, the large pollutant molecules are metabolised and broken down into inert feed substances by the aerobic activity of the bacteria present in the sludge.
ARTES Ingegneria (Bono ARTES) has developed an active sludge process called BIOCLAR, which is a great technological step forward compared to more conventional methods.
The water to be treated is aerated in an area where it is brought into contact with recycled active sludge It then passes on to an oxygenation area and then to sedimentation. The active sludge are continually re-aerated and recycled. The particular characteristics of this process are the high concentration of sludge and its re-aeration in the second stage, which improves its quality and the activity of the bacteria working on the substrate to be degraded. In these conditions, some parameters in the sludge - such as hydraulic load and organic load - are higher than those in traditional equipment, giving a depuration of more than 94% in terms of BOD. 5 and COD.
ADVANTAGES:
- Low-cost on site activities;
- Highly modular and flexible in a large range of capacity;
- Low maintenance;
- Low noise level - no smells;
- Suspended solids and BOD5 greatly reduced (with minimal sludge generation).
