Parkson Plate Packs

Lamella plate packs are the core component of a lamella clarifier.

They consist of a series of closely spaced, inclined plates that:

• Increase settling surface area 
• Reduce the distance solids must fall 
• Improve separation efficiency 

In a Parkson lamella clarifier, these plate packs are responsible for nearly all of the system’s solids removal performance.

Most Parkson lamella clarifiers in operation today are 10–30+ years old.

Over time, plate packs can degrade due to:

Sludge and solids build up on the plates, reducing effective settling area.

Older plates may lose their shape or structural integrity.

Certain wastewater streams can damage plate surfaces.

Older plate geometry may not maximize settling efficiency compared to modern designs.

You may need new Parkson lamella plate packs if you are experiencing:

• Cloudy or inconsistent effluent 
• Solids passing through the clarifier 
• Increased chemical usage 
• Reduced system capacity 
• Frequent cleaning or maintenance 

If your clarifier is no longer producing clear water, the plate packs are often the root cause.

Replacing your plate packs can restore—and often improve—performance.

Modern plate packs provide better settling, resulting in clearer discharge.

Higher efficiency plates can handle greater flow rates within the same footprint.

New designs minimize fouling and improve sludge movement.

Improved performance reduces chemical usage and downtime.

Yes—and in many cases, this is the best option.

You are not limited to identical replacement plates.

Modern plate packs can be designed to:

• Improve flow distribution 
• Eliminate dead zones 
• Increase effective settling area 

This means your existing Parkson lamella clarifier can perform better than it did originally.

Every clarifier is slightly different.

Replacement plate packs can be custom-built to match:

• Existing tank dimensions 
• Plate angle (typically 50–70°) 
• Plate spacing (commonly ~50 mm) 
• Flow requirements 

This allows for a seamless retrofit without major structural changes.
