Indofab Flocculators are designed with 2 or more sets of Flocculation paddles to give desired results of flocculation. The Paddle Size is selected such that the Velocity Gradient G is obtained with rated design power at Standard Speeds to sweep 15% to 25% of the Flocculation zone area. Indofab Flocculators are provided with Indofab Drive Heads for best results and trouble free operation. The Drive heads are capable of taking Torque as well as Axial & Topping loads of the Flocculator. Indofab Flocculators are modular in Construction and all paddles are mounted on Radial Structural Supports fixed to the Hollow Pipe Shaft. For large size Flocculators a steady bearing guide at bottom is preferred to avoid excessive Shaft diameter. All the Components are carefully designed for stability in continous operation and material of construction are selected to suit process requirements.

• Indofab Flocculator Mechanisms are suspended from Mechanism Support Spanning the Tank walls and resting on it.
• The Flocculator is supported by Indofab Drive Stub Shaft connected to the Alloy Steel Schedule Pipe through a rigid coupling.
• The Central Shaft structurally supports the 2,3 or 4 series of paddles as per the design. Many Designers have opted different deisgns like Horizontal , Multiple flocculators, coaxial & so on.
• Large Size Independent Flocculators are provided with steady guide bearings. International Design references are used for geometric & Mechanical design of Flocculators to achieve best results.

• Indofab Flocculators are available from 0.5 Mtr Diameter / Square to 5 Mtr Diameter/Square with Varying Depths.
• Flocculators with Carbon Steel Epoxy Painted, Galvanized Steel, AISI 304, AISI 316, FRP lined, Rubber Lined Constructions.

• Flocculation is a mixing technique that promotes agglomeration and assists in the settling of particles. The most common used coagulant is alum, Al2(SO4)3•14H2O.
• The chemical reaction involved:
  Al2(SO4)3•14H2O → 2Al(OH)3(s) + 6H+ + 3SO42- + 8H2O
  During flocculation, gentle mixing accelerates the rate of particle collision, and the destabilized particles are further aggregated and enmeshed into larger precipitates. Flocculation is affected by several parameters, including mixing speeds, mixing intensity, and mixing time. Flocculation is usually carried out by Mechanical Mixing through Agitators called flocculators having Paddles. The Entire system is designed in such a way that a reasonable G value (Velocity Gradient) is achieved assisting the Floc formation and ensuring optimum utilization of flocculants.
