The principle of sludge recirculation, increasing the particle contact, may be used for precipitation of calcium carbonate as it is normally used for flocculation.
The 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.
