Are you facing challenges with budgets, limited space, or elevated solids in your water treatment processes? Monroe Environmental’s Lamella Plate Vertical Clarifiers are engineered for high-efficiency solids removal in a compact footprint — delivering up to ten times the settling area of conventional clarifiers at a lower cost.
Why Choose Monroe’s Lamella Plate Vertical Clarifier?

Monroe also offers versatile Horizontal Plate Clarifiers which utilize cross-flow parallel plate technology capable of removing floating contaminants as well as settleable materials, all with a lower total height requirement.
Vertical Clarifier Applications
Vertical Plate Clarifier Case Studies
Water | Wastewater Clarifiers Meet New Molybdenum Regulations at Hazardous Waste Landfill
A hazardous waste landfill required an upgrade to its wastewater treatment system to comply with new, more stringent molybdenum regulations. Monroe Environmental helped design and implement a solution.
Water | Vertical Plate Clarifier Removes Mercury & Humic Acid
A company that produces testing and measurement equipment needed to remove solids containing mercury and acid fines from their incoming process water stream.
Water | Lamella Clarifier Retrofit
Rebuild of two underperforming Lamella Clarifiers to address the stresses of elevated liquid temperatures, and internal structural and process deficiencies.
Water | Vertical Clarifier for River Water
Lamella-type Plate Clarifier is providing the same amount of settling capacity as a 12-foot diameter Circular Clarifier.

Designed for Your Process — Options to Enhance Efficiency
- Chemical Mixing & Flocculation: Optional flash mixers and flocculators improve settling for difficult or fine solids.
- Custom Materials of Construction: Mild steel (industrial coating or lined), stainless steel, alloys, FRP, or plastics (Polypropylene, PVC, CPVC, HDPE) to match your process and environment. Standard plates are thermoplastic or stainless steel, but can be offered in FRP as well. NSF-61 approved materials can also be offered for potable water applications.
- Integral Sludge Thickening: Circular sludge thickener tank with mechanical drive to increase percent solids and expand sludge storage volume.
- Sludge Pumps and Dewatering Equipment: Optional low-shear sludge pumps can be provided, as well as holding tanks and dewatering equipment such as a filter press.
Clarifier Maintenance Made Simple
One of the key advantages of inclined plate clarifiers is minimal maintenance. With no mechanical components within the plate packs, routine upkeep is straightforward and infrequent. Operators typically need only perform periodic visual inspections and occasional rinsing to ensure continued efficiency—helping to keep your maintenance routines simple and non-disruptive.

Power and Operational Cost Considerations
Inclined plate clarifiers are engineered for efficiency, with modest power demands compared to many traditional separation systems. Their design typically utilizes slow-moving drives and low-horsepower motors—often requiring less energy than conventional clarifiers or mechanical alternatives.
This efficient operation helps to substantially reduce ongoing operational costs, making these clarifiers a cost-effective solution for both municipal and industrial facilities. The simplified mechanics not only cut down on energy expenses, but also minimize maintenance needs over the long term, adding further value to the system’s lifecycle.
