Packaged Water Treatment Systems

Package Systems combine MRI’s proven flow control, clarification, and sludge handling into a single tank.
Variable-speed Flocculators maximize floc formation, Inclined Plate Settlers maximize settling, and a floor-hugging, Hoseless Sludge Collector clears settled particles end-to-end. Optional membrane filtration provides high quality potable effluent. Optional rapid mixers ensure complete coagulation.

MRI Packaged Water Treatment Systems

Proven MRI Packaged Water Treatment Systems
Provide Maximum Flow in Minimum Space

Backed by more than 35 years of design and manufacturing experience, MRI’s Packaged Water Treatment Systems combine into a single tank the reliable, all-stainless steel, space-saving components proven through years of use in large municipal treatment systems.

MRI Packaged Water Treatment Systems are custom-built to meet specific site requirements and provide high quality effluent for a range of flows. Pre-assembled design makes installation quick and easy, significantly reducing the time and cost typically required for plant construction.

MRI systems are ideal for use anywhere construction space and costs are constrained, including:

  • Rural settings
  • Low-volume treatment plants
  • Campgrounds
  • Mancamps

San Luis Demonstration Plant,
Firebaugh, CA, performs backwash
reclamation at 350,000 GPD

Performance advantages include:

  • Complete, head-to-tail solution utilizes corrosion-resistant, factory-tested, highly efficient and reliable tanks and components manufactured by MRI
  • Increased settling area and water flow in a significantly smaller footprint due to MRI’s High-Capacity Inclined Plate Settlers
  • Optional Meurer membrane filtration module removes microbes and particulates to produce superior effluent quality
  • Custom-build meets site specifications cost-effectively
  • Modular design enables easy and cost-effective installation
  • Systems flows range from less than 150,000 GPD to 1 MGD, resulting in the perfect solution for:
    • Conventional pretreatment
    • Membrane pretreatment
    • Backwash Reclaim
    • Reject Recovery

Water Treatment Callout

Stainless Steel Tanks

Made of T-304 stainless steel, tanks are also available in T-316 or aluminum with complete structural calculations.

Four-stage Flocculation

MRI’s Four-Stage Flocculation consists of three variable-speed horizontal Paddle Wheel Flocculators operated by a single drive unit. A final hydraulic stage maximizes settling. Options for three, two and single-stage flocculation are available.

The standard flocculator has a 20-minute detention time and is custom designed to provide a mixing G-value appropriate for your application.

MRI Inlet Diffuser

Incorporated into MRI baffles, the MRI Inlet Diffuser* controls the flow from the flocculator to the settling area to ensure even distribution and eliminate floc shear.

MRI High Capacity Inclined Plate Settlers

MRI High-Capacity Inclined Plate Settlers* provide the highest effluent quality available from any plate settler. Easy maintenance and durability are provided through a completely accessible, robust, top deck, and individually removable plates.

MRI Hoseless Cable-Vac™ Sludge Collector*

Equipped with an above-water Reel-to-Reel Drive* that ensures reliable power without tensioning, the MRI Hoseless Cable-Vac Sludge Collector* is designed to operate under plate settlers and other low profile areas.

Preferred by engineers, the patented system offers virtually maintenance-free operation and quick, simple installation due to the elimination of flexible hoses that can interfere with plate settler operation, freedom from guide rails, and the use of all-stainless steel long-life wheels and bearings and a simple cable-winch drive.

Ladder & Railed Walkway

Ladder and railed walkway allows easy operator access over the tank to maintain drive mechanisms.

MRI Control Systems

Prewired to Package System drives, MRI utilizes state-of-the-art Rockwell Automation components with PLC-based programming available for Ethernet integration to plant-wide SCADA systems.

Optional Sludge Thickener

The Sludge Thickener is an optional attachment for the Hoseless Cable-Vac Sludge Collector. Consisting of an array of “pickets,” the Sludge Thickener can be run continuously and produce settled solids up to 2%.

Optional or Stand-Alone Pressurized Filtration Membrane Module

Available as a separate module, Meurer membrane filtration is ideal for water treatment, either pre- or post-treatment or stand-alone. Benefits include energy-efficient operation, significantly higher effluent quality, and increased capacity–all in a smaller footprint than conventional systems. Meurer
membrane filtration modules offer superior permeability and tensile strength with a .1 micron pore for pressurized microfiltration.
