baffles for water / wastewater treatment

Baffles are used in flocculation chambers to control flow distribution, separate each stage, and facilitate agglomeration of sludge particles. With or without ports, baffles direct flow throughout the basin. Helical flow diffusers reduce velocities entering the sedimentation basin.

MRI Baffles for Water / Wastewater Treatment

The Key to Efficient Flow Management

MRI’s experience in settleable solids removal processes has led
to the development of a complete family of baffles, troughs, trusses,
supports, and flow diffusers—all geared to optimize flow

To see the advantages of MRI’s flocculators, read about MRI’s Flocculation System.

When strategically placed in flocculators, clarifiers, and aerators,
MRI baffles increase the control of flow distribution and treatment
duration at various stages.

Made of all stainless steel, MRI’s plank baffles are superior to
redwood, fiberglass, or concrete. They:

  • Are quicker and easier to install or reconfigure
  • Save natural resources and prevent possible chemical contamination
  • Can be installed or retrofitted in any basin to improve efficiency
  • May be slotted, ported, or solid, depending on the application

Performance Advantages

MRI baffles, helical flow diffusers, troughs, and trusses are:

  • NSF-61 approved
  • Made of 304/316 stainless steel
  • Long lasting and easy to install
  • Equipped with “Rotating Bottom Plank” that can be opened for easy basin cleaning
  • Suitable for use in seismic prone applications: the Rotating Plank can swing back and forth to protect baffles from water-movement damage
  • Baffle planks are available up to 12 ft. long

MRI’s Stainless Steel and Aluminum Baffles
offer a permanent solution for:

  • Aeration basins
  • Hydraulic Flocculators
  • Flocculator Staging Baffles
  • Chlorine Contact Basins

MRI builds the most commonly used hydraulic flocculators such as the baffle channel type.

Ported Baffles are used to distribute flow evenly across a basin.

MRI’s stainless steel planks slide into support channels mounted on concrete or stainless steel columns. Planks are typically 12” wide x 1.5” thick and up to 12’ long. Other widths are available.

Key Features Boost Clarifier Efficiency & Flow Management

Port Helical Flow Diffuser
Port Helical Flow Diffuser

Port Helical Flow Diffusers

Patented design rapidly diffuses inlet velocities to prevent floc disruption. 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 assuring evenly distributed flow.

Metal Weave Baffles

Metal WeaveCorrosion resistant, “Metal Weave” stainless steel baffles are available in 304 or 316 material. 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.

Ultra-Rigid Truss Support Systems

Coupled with ultra-rigid
truss support systems,
MRI troughs offer
unmatched stability in clarifier functions. Troughs can be manufactured with a flanged end or can protrude through basin walls with a water stop incorporated in to the trough.

Distribution Baffles

Slotted or ported baffles help make flow more even and efficient to facilitate solids removal.

Flocculator Baffles

Flocculator baffles can be:

  • Serpentine
  • Under/over or double under/over
  • Slotted or ported and directly lined-up to control flow

MRI Inlet Infuser.*

The patented MRI Inlet Infuser is the most efficient, inexpensive method available to diffuse inlet velocities. Flow entering the Inlet Infuser is gently split in half and exits each end of the Inlet Infuser, which doubles the area of the inlet port. This results in the flow entering the basin with 75% less velocity. Velocity reduction is accomplished in a rotating motion, which does not damage floc structure.
