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 5: threshold pH regulation system.

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.
