Dosing mixer, flocculation mixer is one of the most commonly used mixer for water treatment industry, widespread water treatment and elimination of colloid stability of the first and second stages, especially the requirements on the second stage of the flocculation mixer is particularly high, because it is directly related to the colloid destabilization to a precipitation process.
The flocculation process flocculation mixer used for water supply and drainage in the main coagulation process, flocculation mixer is the role of collision to water colloid particles adsorption and gradually crystallized into a certain size sail sail flower flower, gradually settle to the sedimentation tank. Mixing intensity and mixing time is the key to flocculation, flocculation tank mixing intensity should be decreased, the speed of the blade center of a stall mixer should be gradually decreased, to meet the sufficient flocculation time.
The flocculation mixer can meet the requirements of the flocculation rule, with stirring intensity of different stages of the flocculation process, changes can be suitable for water and the water temperature, water head has the advantages of little damage, simple basin structure, convenient combination of external energy.
Flocculation mixer can change with the change of water quantity, the turbidity of the raw water and the change of dosage, and then adjust the intensity of the mixing in order to achieve satisfactory flocculation effect.
According to the different installation methods can be divided into vertical and horizontal mixer, the general use of vertical mixer, mixing blades using a box type flocculation mixer.
