Lamella Plates: Lamella clarifiers consist of a series of inclined plates (lamella plates) arranged at an angle within a rectangular tank. These plates create a large surface area for sedimentation while maintaining a compact footprint.

Inlet and Outlet Systems: The system includes an influent inlet for dirty water and an outlet for clarified water. A sludge collection area is typically located at the bottom of the tank.

Lamella clarifiers use a combination of inclined plate technology and chemical treatment to efficiently remove suspended solids from water. The process enhances sedimentation, allowing for high-performance treatment in a compact footprint.

Here is a design showing the inside view of the lamella plates

Step-by-Step Process

1. Influent & Chemical Dosing
Raw water containing suspended solids enters the clarifier. Coagulants are added to neutralise the charge of fine particles, allowing them to bind together. Flocculants are then introduced to form larger, heavier flocs that settle more easily.

2. Upward Flow Through Lamella Plates
The treated water flows upward through a series of inclined lamella plates. These plates significantly increase the effective settling area while maintaining a compact design. As water rises, gravity causes the heavier flocs to settle onto the plate surfaces.

3. Accelerated Sedimentation
The inclined angle of the plates encourages solids to slide downward, enabling faster and more efficient sedimentation compared to traditional settling tanks.

4. Sludge Collection
Settled solids accumulate as a layer of sludge on the plates and slide down into the sludge hopper at the base of the unit, where they can be removed.

5. Clarified Water Discharge
Clarified water exits from the top of the system, with significantly reduced turbidity and suspended solids, making it suitable for discharge or further treatment.

Space Saving Design:
Lamella clarifiers require less space compared to traditional sedimentation tanks, making them ideal for facilities with limited space.
When combined with chemical treatment, the settling area required is further reduced, meaning your site can handle larger water treatment demands without requiring additional space.

Maximized Sediment Removal:
By combining lamella clarifiers with coagulants and flocculants, we achieve superior sediment removal rates. The coagulants neutralize fine particles, while flocculants help those particles cluster into larger, faster-settling flocs. This accelerates the sedimentation process, providing clearer water with fewer suspended solids.

Increased Performance and Efficiency:
The inclined plates increase the effective settling area, allowing for quicker and more efficient removal of suspended solids.
Using coagulants and flocculants leads to better water clarity and reduced turbidity. This ensures that treated water meets stringent environmental regulations for discharge, helping you avoid fines and ensuring your project stays compliant with local, state, and federal standards.

High Flow Rates:
They can handle high flow rates while maintaining effective sedimentation, leading to better overall efficiency in water treatment processes.

Flexibility:
Lamella clarifiers can be used in various applications, including municipal wastewater treatment, industrial water treatment, and stormwater management.
