Aerobic water purification pilot plant
The activated sludge pilot plant consists of an oxidation reactor and of a settler according to the traditional diagram of singlestage sewage treatment process.
Biomass is oxidized in a reactor with agitator by the air blown by a compressor. The processed liquid is sent to the settler through an overfl ow. The sludges settling at settler bottom are recycled by a recycle pump into the oxidation tank.
The process unit enables to develop and analyze the following issues:
- Purification efficiency versus the following parameters:
- composition of water under to be treated
- residence time
- organic load
- pH in oxidation tank
- concentration of dissolved oxygen
