Why Rebuild or Retrofit Existing Clarifiers?
Rebuilding and replacing the internals of a concrete or steel tank clarifier is a quick, cost-effective solution versus constructing an entirely new system. The clarifier tanks often maintain a suitable operating condition while the skimmer arm, center well, drive assembly, and sludge rakes corrode and wear beyond an acceptable level.
The benefits of a Monroe Environmental Clarifier Rebuild are straightforward and simple:
- Faster installations & reduced total cost
- Minimal clarifier downtime
- Improved performance
- Reduced future maintenance costs
These benefits are realized because we are often able to fully assemble clarifier equipment before it ships to the job site. In such a case, we inspect and test every bolt, weld, and panel to make sure that each component fits together perfectly before it is shipped to site and installed. This key step can be the difference between a few days of simple installation or weeks of fitting, engineering, and re-working equipment in the field. By reducing installation time, projects can often be completed ahead of schedule with minimal labor cost.

Clarifier Rebuild Examples
Circular Clarifier: Chemical Manufacturing Plant
Before: Existing 55 ft. diameter Scraper Clarifier at chemical manufacturing plant. Middle photo: New Clarifier internals completely assembled in Monroe shop. After: Installation of new internals as well as drive, bridge, and walkway.
Primary Clarifier: Municipal Wastewater Treatment
Before (Photos 1 & 2): Upgrade of four 250 ft. Primary Clarifiers. The project included converting the sludge rakes to higher efficiency spiral scrapers and rehabilitating existing drive units, as well as replacing influent wells, column supports, weirs, baffles, and launders with a combination of mild, coated steel and non-corrosive stainless steel members. After (Photo 3): One of the Primary Clarifiers ready to return to operation.
Vertical Clarifier: Plating Company
Before (Photos 1 & 2): Vertical Clarifier rebuild for a plating company. After (Photo 3): Refurbished Vertical Clarifier leaving Monroe facility.
Secondary Clarifer: Municipal Wastewater Treatment
Before (Photo 1): Secondary Clarifier 130 ft. Clarifier rakes fully assembled in Monroe shop prior to shipment. Photo 2: Installation of rebuilt components at a 25 MGD WWTP. After (Photo 3): Secondary Clarifier ready to return to operation after just a three day installation.
