The floc quality and formation are significantly influenced by the flowing aspects: ? The quantity, mixing type and quality of the flocculation agent ? The reaction period of the flocculation agent in the sewage sludge until the following dewatering phase (both too short and too long are detrimental) ? The sludge type (consistency and contents) It is generally accepted that a high floc quality has a significant influence on the dewatering performance. The mixing unit, where the plant component contacts the sludge with the polymer, controls the flocculation and quality significant. The size of the flocs is (additionally to the quality of the polymer) dependent to the level of mixture. The diagram below shows a comparison between two mixing units (A and B) by using the same polymer. The result is clear (measurement method: FlocSens). The content of large flocs rose up to over 50% in the total mass, the content of middle and small flocs decreased rapidly. The result: Ideal dewatering conditions for downstream dewatering aggregates (decanter or filter press). Our mixers are also integrated in our FlocFormer, thus leading to optimal flocculation (pelleting) when used in combination with this peerless mechanical floc treatment process. The dewatering results are extremely impressive as a result. The FlocStirr is suitable for intensive mixing in exposure time. For example: ? Paper industry ? Fruit juice production ? Sewage treatment ? Sludge treatment FlocStirr® aquen Best Practice large flocs medium flocs small flocs Operating mode The special function of FlocStirr is the radial feed stream of polymer in a rotating shaft of the motor. Liquid admixture (especially polymer) is inserted in the medium by the perforated and rotating shaft under pressure and rotation. In addition to the selection of proper polymer, the optimal mixture can be reached by handling the pressure settings (inputted mass/time unit respectively kg/TS) and rotation speed (motor).

In consequence of setting a too high number of rotations, the flocs can be damaged otherwise by using a too low number of rotations, the medium cannot be totally stirred. Our dynamic inline mixer can be realized in several types and materials for every case of operation. The control electronics are delivered in a separate control box for installation on the wall or in your switch cabinet.
