Baffles

For Optimized Flow Management

When strategically placed in flocculators, clarifiers, and aerators, MRI baffles enhance flow distribution control and treatment duration at various stages. Constructed from all stainless steel, MRI’s plank baffles outperform redwood, fiberglass, or concrete alternatives, offering quick and easy installation or reconfiguration, conservation of natural resources, and prevention of chemical contamination. Suitable for new installations or retrofits, MRI baffles can be slotted, ported, or solid, depending on the application.

To increase clarifier efficiency, the following Flow management devices are available:

Port Helical Flow Diffusers

Patented design diffuses inlet velocities to prevent floc disruption, ensuring even flow distribution. Flow entering the diffuser is gently split in half and exits in a spiraling motion at less than .5 FPS. Flow covers a 180° area at exit, further reducing velocity and ensuring even flow distribution.

Metal Weave Baffles

Corrosion-resistant stainless-steel baffles available in large, single-sheet fabrications for new or retrofit applications. These baffles are suitable for new or retrofit applications, and rectangular or circular basins. Exclusive metal weaving process allows fabrication of large, single sheet stainless steel baffles.

Distribution Baffles

Slotted or ported to facilitate even and efficient flow for solids removal.

Flocculator Baffles

Available in

Serpentine

Under/over, or double under/over designs, and

Slotted or ported and directly lined up to control flow

Inlet Diffuser

The patented MRI Inlet Diffuser is the most efficient and cost-effective method for diffusing inlet velocities. The design gently splits the incoming flow in half, directing it out of each end of the infuser, effectively doubling the inlet port area. This process reduces the flow velocity by 75% before it enters the basin. The reduction is achieved through a rotating motion that preserves the integrity of the floc structure.

Principle of Operation

MRI baffles operate by strategically managing and directing water flow in treatment basins such as flocculators, clarifiers, and aerators. Their primary function is to enhance flow distribution and treatment duration, ensuring efficient solids removal and overall process optimization. Here’s how they work:

Key Steps

Flow Management

MRI baffles are placed in specific configurations within the treatment basins to control and direct the water flow. This strategic placement helps to distribute the flow evenly, preventing short-circuiting and ensuring that all areas of the basin are effectively utilized.

Velocity Reduction

The patented design of MRI’s port helical flow diffusers and inlet infusers splits the incoming flow and reduces its velocity. This is achieved by gently splitting the flow in half and exiting in a spiraling motion, covering a 180° area at the exit point. The reduced velocity prevents the disruption of floc formation and ensures even flow distribution.

Improved Clarification

As the water passes through, solids drop out of suspension and are collected in the sludge zone. This leads to clearer effluent exiting the clarifier.
