quick overview :
The activated sludge pilot plant consists of an oxidation reactor and of a settler according to the traditional diagram of single-stage sewage treatment process. Biomass is oxidized in a reactor with agitator by the air blown by a compressor. The processed liquid is then sent to the settler. The sludges settling on settler bottom are recycled by a recirculation pump into the oxidation tank. The water flowing out of the settler is conveyed to a drain. Data acquisition is carried out by a specific software.
TRAINING PROGRAM:
The process unit enables to develop and analyze the following issues:
• Purification efficiency versus the following parameters:
- composition of water to be treated
- residence time
- organic load
- pH in oxidation tank
- concentration of dissolved oxygen
