MRI Inclined Plate Settlers have proven for decades to deliver the highest flow rate and solids removal available, providing unsurpassed clarifier function. Featuring the unique, patented hydraulic Flow Control System, MRI Inclined Plate Settlers distribute flow evenly across the entire system. The even distribution enables a consistent flow rate and low turbidity throughout the sedimentation process, producing high quality effluent with less than 1 NTU, meeting or exceeding regulations. As a result, MRI Inclined Plate Settlers are recognized as the highest performing and most reliable system available.

Other key design features include laser-cut orifices, which guarantee that all points of effluent removal are identical, and a rigid design that enables the Flow Control System to support up to 250 pounds – strong enough to be walked on during installation and / or inspection.

Performance Advantages

NSF 61 logo

MRI’s patented Inclined Plate Settlers ensure:

  • Ease of installation and maintenance with the patented, walkable Flow Control Deck
  • Up to 80% smaller footprint than open basin clarifiers
  • Flexible design, which enables retro-fitting of existing facilities
  • 100% stainless steel fabrication for unsurpassed dependability
  • NSF 61 listed and certified

Key Features Only from MRI Inclined Plate Settlers

Hydraulic Flow Control Deck, consists of stainless steel tubes with precise metering orifices at the top of each plate settler that extract flow evenly.

Flow is regulated across each plate settler and across the entire basin, providing more flow control and the most uniform distribution available.

Increases effective settling area by up to eight times, greatly enhancing effectiveness and productivity. Facilities can treat more water without increasing basin size, resulting in far greater efficiency and cost savings.

Easily adaptable components allow for use in a variety of installations.

All stainless steel fabrication, including plates, support beams and effluent troughs, provides durability that lasts a lifetime.

Uniquely Designed for Easy Maintenance

Flow control orifices in the effluent tubes draw the flow up evenly across the entire plate width, utilizing the whole surface area for maximum settling efficiency.

Added Value of Plate and Trough Covers

Optional use of covers for plate settlers and troughs can eliminate plate cleaning maintenance and greatly reduce operating costs. Plate settler covers block sunlight from reaching the plate settlers, thereby eliminating algae growth, preventing bacteriological contamination due to presence of coliform, and preventing debris from blowing onto the plates. Covers are custom fitted and made of T-304 stainless steel with EPS foam underneath, allowing the covers to float without impeding water flow. Surface tension of the water holds the covers in place; however, hold downs are also available for drained basins. 

Guards against: 

  • Algae growth 
  • Ice formation 
  • Debris
