Lamella Clarifier / Settler

The most effective settling tank solution

Multiple SIEBTECHNIK TEMA Lamella Settler on site, in Australia

Our Lamella Clarifier / Settler is the space efficient settling solution for purification of water and wastewater, including re-use of process and backwash water.

Gravity Sedimentation

Gravity sedimentation is the most common and reliable method to separate suspended solids from liquids. It is used in nearly all water treatment, wastewater treatment, mineral processing and other processing plants. Traditional gravity settlers require large footprints and high capital investments. With the SIEBTECHNIK TEMA Lamella settler space requirements are reduced by 90% or more, at a fraction of the cost of a traditional settler, while operating essentially maintenance free.

It is a well known fact that the settling area is the most significant aspect of the settling capacity of any settler. With the inclined plate concept, the effective gravity settling area becomes the area of each plate projected on a horizontal surface. As a result, up to 10 square meter of settling area become available for each square meter of floor space occupied by the unit. This distinct advantage, when combined with the Lamella settler’s unique flow distribution and simplified sludge removal technique, insures optimum performance.


Space Efficient & Versatile

Our Lamella Clarifier / Settler is the space efficient settling solution for water and wastewater treatment, including reuse of process and backwash water.

Our system is a complete modular solution that includes a flocculation tank, mixers and a sludge scraper. This comprehensive package ensures a seamless, integrated process from start to finish. The modular design allows for easy installation and adaptability to different requirements, making it a versatile choice for many applications.

Our Lamella settler is commonly used in potable water and sewage treatment works, as well as the pulp and paper, chemical process, food processing, surface treatment, power, mining & minerals, iron and steel industries. Applications include the purification of raw water, primary and secondary effluents, re-use of process and backwash water.

Benefits of the Lamella Clarifier / Settler

  • Significantly reduced footprint: The Lamella System’s design reduces its footprint by up to 90% compared to conventional clarifiers, making it an ideal choice for space-constrained areas.
  • Operational Economy: Known for its low maintenance requirements, the Lamella Clarifier / Settler also eliminates the need for replacement parts, ensuring cost-effective operation over time.
  • Modular Design: The modular nature of the system facilitates easy expansion, allowing for scalability and adaptability to changing processing requirements.
  • Cost Efficiency: On a total installed basis, the Lamella Clarifier / Settler proves to be more cost-effective than traditional options, providing economic benefits from installation to operation.

Simplicity and Flexibility:

  • Pre-assembled factory design: The system is pre-assembled at the factory, resulting in shorter delivery times and minimal field assembly.
  • Indoor or Covered Installation: It can be installed indoors or under a cover at a significantly lower cost.
  • Easy relocation: Designed for easy movement and repositioning.
  • Minimal moving parts: The system has far fewer moving parts, reducing the likelihood of mechanical failure.
  • Ease of operation: Starting and stopping the system is simple and hassle-free.
  • Lightweight: The Lamella System is lighter in weight, making it easier to install and more mobile.

Versatile installation options:

  • Expandability: Its modular form supports easy expansion to meet growing needs.
  • Flexible Tank Integration: It can be installed as a freestanding unit or integrated into a concrete tank.
  • Environmental Resistance: Lamella’s performance is not affected by wind or thermal currents, ensuring consistent operation in a variety of environmental conditions.

Lamella Packs for Concrete Tanks: Enhancing Capacity Efficiently

Concrete tanks are ideal for high-capacity installations. At SIEBTECHNIK TEMA, we recognize the importance of maximizing the effectiveness of these facilities. Installing Lamella plate packs in existing settling tanks is a simple and efficient solution to boost plant capacity.

Our plate pack assemblies are designed for hassle-free integration. They are delivered as complete, ready-to-install units, significantly reducing both the installation time and overall project cost. Once installed, these settlers function just as effectively as freestanding units. The process is simple yet effective: solids settle on the inclined plates and slide into the collection area below, all driven by gravity.
