Flocculation process
The purpose of flocculation is to create favorable conditions for the slow mixing stage, which is followed by rapid dispersion of the coagulant by the rapid mixing unit. In other words, its purpose is to accelerate the collision of particles, which causes the accumulation of unstable hydraulic colloidal particles and their transformation into filterable and settling particles.
Flocculation process
Particle flocculation is actually done in two stages. The first step involves adding a coagulant to reduce or limit the gravitational forces between the particles. Particle stability. This process is called coagulation. The collision of very small particles and their transformation into the sound of a clot occurs as a result of molecular movements and physical mixing of the liquid, and this phenomenon is called clotting.
Description of options in the flocculation process
These types of flocculators spin at low speeds and are capable of forming concentrated rotations with very low shear forces; However, vertical axis flocculators with smooth mixing blades are capable of producing very large and heavy flocs if anionic polymers are used in close proximity to alum in a particular application chain. This example only emphasizes the importance of the relationship between process selection and flocculation equipment.
Combined system of flocculators and ducts with soothing wall
This method consists of combining two systems. This system reduces the size of fluctuator units, saves operating costs and important parts, and increases reliability. The flocculator units must be in the last stage of the flocculation process.
