Clarifier Rebuilds and Retrofits
Clarifier Rebuilds and Retrofits
Rebuild and replace clarifier internals for long term performance
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.

Vertical Plate Clarifiers: Retrofit at a Catalyst Plant
Monroe designed and fabricated customized rehabilitation kits for two underperforming lamella plate clarifiers that would solve structural and process deficiencies, and be able to be installed without deconstructing the separators. This lowered the total project cost and allowed the plant to execute the retrofit during a scheduled shutdown.
Before: Lamella plate clarifier with internal components that were warped, buckling, and in danger of collapsing under thermal stress.
After: Lamella plates installed after new supports for internal structural and process deficiencies were addressed.
