Description
The ClearFox® Lamella Clarifier reliably separates settleable solids from process and wastewater. The technology is based on the principle of sedimentation, which is significantly enhanced through the use of an inclined lamella package. It is suitable for both industrial and municipal wastewater and can be flexibly used in both primary and secondary clarification stages.
How It Works
- Raw wastewater enters the upper section of the unit through the inlet channel and is directed downward (1)
- From there, the flow is redirected and moves evenly upward through the inclined lamella package (2)
- The lamella modules are tilted at a 60° angle, creating optimal conditions for sedimentation. As the water slowly rises, sludge settles on the inclined surfaces. The settled solids slide downward in counterflow along the lamellae and are collected at the bottom of the tank in a sludge hopper (3)
- The sludge is then removed at regular intervals via a pump. Above the lamellae, the clarified water accumulates (4) and flows through an overflow weir to the system outlet (5)

The technology is based on the principle of sedimentation, which is significantly enhanced through the use of an inclined lamella package. To effectively settle even smaller particles (smaller 50 μm), optional flocculants can be added. These produce larger, settleable flocs that are also then removed through sedimentation. The ClearFox® lamella clarifier is available as a ready-to-connect container solution, for underground installation in HDPE tanks, or in concrete structures. Each system is custom-designed and manufactured to meet your specific requirements.
Advantages
- Space Saving
Thanks to the inclined lamella modules, the effective settling area is significantly increased compared to conventional settling tanks, while the required space is reduced. In practice, the ClearFox® lamella clarifier requires up to 90% less space than traditional sedimentation systems. The compact design makes it especially suitable for locations with limited space and allows for easy integration into existing systems.
- Low Operating Costs
Our lamella clarifier operates without any moving parts and needs almost no energy. The lamellae are made of seamless, rotationally molded polyethylene, making them extremely durable and resistant. For operators, this translates to minimal operational and maintenance costs and a consistently trouble-free system.
- Fast Turnaround
For standard sizes, the clarifier is delivered as a ready-to-connect system and is immediately operational. This enables quick integration into both new and existing facilities. Time-consuming assembly work is eliminated, significantly reducing installation costs.
- Flexible Design
The ClearFox® lamella clarifier is suitable for a wide range of applications. It can be used in both municipal treatment plants and industrial processes without any issues. Thanks to the containerized design, the system can easily be expanded as needed in the future. We offer containerized lamella clarifieres in various sizes. Freestanding, below ground, in PE tanks or in concrete tanks: We develop a solution tailored to your specific project.

FAQs
1. What is a ClearFox® Lamella Clarifier?
A ClearFox® Lamella Clarifier is a primary clarification device designed to remove solid particles from liquids, effectively managing raw wastewater with high concentrations of suspended solids. It utilizes inclined plates (lamellas) to enhance the settling process, requiring up to 80% less space compared to traditional settling tanks.
2. How does a Lamella Clarifier work?
Wastewater enters the clarifier through the inlet channel at the top and flows to the bottom of the separator. As it flows upward through the inclined lamellas, solid particles settle onto these plates. The treated water continues to the top, reaching the outlet by passing over a weir. Settled solids (sludge) slide down the lamellas and are collected in a sludge funnel for periodic removal.
3. What are the advantages of using a ClearFox® Lamella Clarifier?
- Space Efficiency: Requires up to 80% less space than traditional settling tanks.
- Chemical-Free Operation: Offers a simple design without the need for chemicals.
