The Solution for Compact Multi-Barrier Systems for Water and Wastewater Treatment, Desalination and Water Recycling.

Developed by WABAG in the 1980s, the lamella settler technology was designed to significantly reduce the footprint of clarifiers following the flocculation and coagulation treatment steps. Since its inception, WABAG’s lamella clarifiers have been successfully implemented in numerous drinking water production and wastewater treatment plants worldwide.

The Process

In the lamella clarifiers, flocculated inlet water flows through the lamella plates, where it undergoes clarification before entering the clarified water channels. Concurrently, the flocculated sludge descends by gravity and is thickened at the bottom of the tank with the aid of a picket fence scraper. The lamella plates are constructed from corrosion-resistant and UV-stable materials, ensuring durability and longevity. They are securely mounted using a robust stainless steel framework, providing structural integrity and ease of maintenance..

Key Features

• Small footprint: Achieves high elimination rates and handles hydraulic loads efficiently. 
• Proven technology: Trusted and implemented in numerous installations. 
• Integrated sedimentation of flocculated sludge
• Integrated sludge thickening 
• Simplified civil structure: Reduces complexity in construction and installation worldwide.
• High process stability: Ensures reliable performance under varying operational conditions.
• Flexible operation:  Modular design allows for adaptable and scalable solutions´.

The process is highly versatile, catering to a wide range of applications—from drinking water and municipal wastewater treatment to industrial water and effluent treatment. It also serves as an effective pretreatment step for seawater desalination plants and supports municipal as well as advanced industrial water recycling facilities. Over the past 20 years, WABAG has successfully implemented over 30 OPUR-SK systems for these diverse applications.
