This pilot presents the process of elimination of carbon, nitrogen and phosphorus pollution by microbiological route. It works by contacting the water to be purified with a bacterial floc in the presence of O2 followed by a phase of separation of this floc. The oxidation basin is preceded by a pool of anoxia, which makes it possible to characterize and differentiate the stages of denitrification and nitrification.
Option 1: secondary settling tank. This option is recommended for using treated water in a drinking water system.
Option 2: agitation system in the feed tank comprising: a circulator and a level probe. This option is recommended if the solution to be treated has a high rate of suspended matter.
Option 3: sludge recycling. This option is recommended for a long-term process.
Option 4: scraper in the cylindro-conical decanter.
Option 6: temperature control system comprising: an immersion heater and a regulator.
Option 7: Data acquisition system including: RS485-ethernet gateway, Ethernet port, acquisition software (Autolink) and a laptop PC.
Option 8: remote monitoring system (supplied with a PC, PLC and software). Manual valves are replaced by solenoid valves.
