The MRI Flocculation System offers an advanced, efficient, and adaptable solution for optimizing the flocculation process in water treatment plants. Its multi-stage approach, combining mechanical and hydraulic mixers, provides precise control over the entire pretreatment process, ensuring effective floc formation and sedimentation. With key features like variable speed mixers, a self-cleaning hydraulic stage, and flexible configuration options, the MRI Flocculation System delivers enhanced performance, energy efficiency, and reduced maintenance requirements.
Mix and Match with our Flocculator systems. MRI Flocculation Systems can use vertical turbine, horizontal paddle wheel, or hydraulic flocculation or a combination in the first three stages, allowing for a wide range of G-values. Basin configuration or preference can determine which device is best suited.
Principle of Operation
The MRI Flocculation System is designed to optimize the flocculation process by integrating multiple stages of mechanical and hydraulic mixing. This multi-stage approach allows for precise control over the mixing intensity (G-values), ensuring effective formation and growth of flocs, which are essential for subsequent sedimentation and filtration processes.
Key Steps:
Rapid Mix Stage:
High-G Vertical Turbine Mixers: Utilize extremely high G-values to quickly disperse chemicals and initiate floc formation.
First-Stage Flocculation
High-G Vertical Turbine Mixers: Maintain high turbulence to encourage initial floc growth.
Second and Third-Stage Flocculation
Mid-G Horizontal Paddle Wheel Mixers: Operate at lower G-values to gently mix and grow flocs without causing shear.
Final Hydraulic Mixing Stage
Extremely Low-G Hydraulic Mixers: Utilize self-cleaning hydraulic mechanisms to create a quiet zone with minimal turbulence.
Vertical Paddle Wheel Flocculators
MRI’s Vertical Paddle Wheel Flocculators are custom-built for various applications, emphasizing performance, reliability, and longevity. These flocculators feature robust components, a complete stainless steel design, and a drive assembly with a gear motor, shaft coupling, and thrust bearing. They mount vertically on bridges or walkways above basins, and custom-built bridges and walkways are available if needed
Horizontal Paddle Wheel Flocculators
MRI’s Paddle Wheel Flocculator offers a unique advantage: the ability to install multiple flocculators on a single drive. This allows for varied paddle configurations and the use of different G-values, enhancing control over flocculation outcomes. Given the increasing use of membrane filtration and the elimination of polymers, precise flocculation control is crucial. Settleability tests, like jar tests, determine efficient rapid mixing and flocculation parameters. For consistent conditions, Paddle Wheel Flocculators suffice; for varying conditions, consider MRI’s Vertical Turbine Flocculator.
