Coagulation and Flocculation KFUPM
A crossflow horizontal shaft paddle wheel flocculation basin is to be designed for a flow of 25000m3/d a mean velocity gradient of 26.7/sec at 10 C and a detention time of 45 minutes. The GT value should be from 50000 to 100000. Tapered flocculation is to be provided and the three compartments of equal depth in series are to be used.
Water processing: Improving flocculation with impellers
Axial flow impellers rakes and gates do not necessarily produce the correct flow regime to achieve good particle distribution throughout the basin. The total flow in the basin will exceed the impeller 39s primary pumping capability by a factor of twoto four times due to the induced flow resulting from the effects of viscosity.

Radial Disc Impeller Enviropax
It is a midrange design between the axial mix and high efficiency axial impeller types so that a large impeller can be used in a flocculation basin yielding good pumping characteristics while imparting the required power with lower tip speeds than typically required by the flocculation process.
Paddle Wheel Flocculators vs Impeller Flocculators JMS
Impeller Style Flocculators. Think of a boat or airplane propeller. The Impeller Style generally takes up less space in a basin and turns at a much higher frequency compared to other style flocculation systems. For Water Treatment systems turbines with a strong axial component are generally chosen.

An Axial impeller is to be used in the design of Chegg.com
Civil Engineering questions and answers. An Axial impeller is to be used in the design of flocculation basin that consist of 3 tanks connected in series with G 70 50 and 30 per second. The three tanks were each dimensioned at 4 4 and 3 for length width and depth respectively. If viscosity is 0.00152 Pa.s and If you know that tangential tip
Types of Vertical Flocculators for Water Treatment Plants JMS
Hyperbolic Flocculators create a specific type of turbulence in the basin with their distinct impeller design. Manufacturers take credit for drag coefficient and the relative velocity to create the floc particle. This type of flocculator uses a design that has the gear box handling all radial and axial forces that might occur.
Mixing Flow Patterns and Impeller Types Learn How Flow
The most common flow patterns in mixing are axial down and up and radial side to side flows. These flow patterns describe the generic classes of impellers: axial and radial. Axial down and up pumping is an important flow pattern because it addresses two of the most common challenges in mixing solid suspension and stratifi ion.
