chemical carbonate removal (softening) with sludge recirculation reactor – Densadeg®
The Densadeg® can be used for water softening.
The principle of sludge recirculation, increasing the particle contact, may be used for precipitation of calcium carbonate as it is normally used for flocculation.
Densadeg® with its external sludge recirculation system and the use of polymer in a specific reactor allows speed at 30 to 50 m/h for a minimum volume of sludge production (concentrations between 300 and 1000 g/l at extraction level). It combines lamellar settling and integrated thickener.
