JMS Mega-SETTLER (Plate Settler System)

The plate settler’s roots date back to 1904, when sanitary engineering pioneer Allen Hazen introduced the concept that sedimentation is a function of basin surface area, independent of retention time. That development led engineers to add diagonal steel plates in the sedimentation basins to increase the effective projected horizontal surface area. At JMS, we build upon that concept by utilizing our own Mega-PROGRAM (Plate Settler Design Program), developed over the last decade, to calculate the effective projected horizontal surface area required for a given design flow, while optimizing other design variables critical to the process. The result is the most efficient approach possible to maximizing the treatment capacity of the basin and improving effluent quality.

JMS Mega-SETTLER (Plate Settler System) Advantages

TFCA™ Top Flow Control Angle

  • Patented feature controls headloss and clogging issues other designs do not address.
  • Provides headloss control for even laminar flow to exit, minimizing clogging
  • Operators can walk on top of plates for wash-down and service
  • TFCA™ angle geometry adaptable to suit water or wastewater applications

Dual Side-Loaded Effluent Troughs

  • Addresses the issues of reduced visibility, access to the plates, and velocity accumulations resulting in imbalanced flow.
  • Minimizes distance settled water travels to trough, flow across plate remains balanced
  • Provides view of, and access to the top of the system

2VNP™ Adjustable V-Notch Weirs

  • Adjustable weirs fine-tune water elevations to accommodate fluctuations in plant flow.
  • Two V-notch weirs per plate for even flow distribution across all plates

Mega-PROGRAM (Plate Settler Design Program)

  • The JMS Mega-PROGRAM is the most advanced and comprehensive plate settler design program in use.
  • Thousands of Mega-SETTLER designs optimized for engineers and municipalities

Dual Side-Loaded Effluent Troughs

JMS Dual Side-loaded Effluent Troughs help address the issues of reduced visibility, access to the plates, and velocity accumulations resulting in imbalanced flow.

Maximizing Space

Increasingly, treatment plants are asked to do more and the need for maximizing what’s available has never been more evident. At JMS, we design our Mega-SETTLER to best suit any basin geometry and sludge collection system. This approach can dramatically reduce the footprint of a conventional sedimentation basin, often by as much as 50 to 90%. It can also significantly increase the treatment capacity of existing basins while improving effluent quality. Compared to similar out put sedimentation basins without plate settlers, the Mega-SETTLER requires a much smaller footprint, performs consistently better, is more reliable, and when all capital, construction, and operational costs are factored in over the life of the system can actually cost less.

Simply the Best

Constructed of 100% stainless steel, every JMS Mega-SETTLER is designed to provide the highest level of efficiency and durability, while minimizing maintenance demands. Our experts continually analyze field data and apply that knowledge to each new system. As a result, we can select the right combination of variables to optimize the performance of your system. The Mega-SETTLER line represents the efforts of JMS professionals with decades of experience in the sedimentation and flocculation industry, all committed to both process efficiency and customer satisfaction.

JMS Mega-SETTLER (Plate Settler System) Success Story

JMS Mega-SETTLER (Plate Settler System) Success Story Oak Creek

Located about 15 miles south of Milwaukee, the Oak Creek Water & Sewer Utility provides water and sewer service to 70,000 people in Milwaukee County. To meet growth demands of the area, the capacity of the Oak Creek WTP has grown from its original six million gallons/day (MGD) to a current capacity of more than 34 MGD. In the latest plant upgrade, engineers hoped to not only improve water quality but also maximize the space available for expansion. They did so by specifying the use of a JMS Mega-SETTLER, installed downstream from a newly-installed Mega-FLOC (Horizontal Paddle Wheel Flocculator), also from JMS. This change greatly reduced both the size of the sedimentation basins and the building needed to house them.

Oak Creek WTP was in a unique position to be able to compare and contrast systems with and without JMS technology at work, as several basins were traditional sedimentation basins and one was a high-rate basin with older plate settlers. Plant operators report the performance from the basins with the JMS Mega-SETTLER is much better than the others, citing an average effluent turbidity of 0.2 – 0.4 NTU. They also say that, when complete, the plant expansion came in $6 million under estimates with better process performance than any of their previous expansions.
