Lamella Clarifier

A Lamella Clarifier, also known as an incline plate settler or tube settler, is a water treatment device use for the separation of solids from water through the process of sedimentation. It is design to maximize the surface area available for settling while minimizing the footprint of the clarifier.

Process Description

When water enters the Lamella Clarifier, it flows through the incline plates. The flow is usually distribute evenly across the plates to ensure uniform settling. As the water flows over the plates, suspend solids in the water begin to settle due to gravity. The incline plates provide a larger effective settling area, allowing for improv particle settling efficiency.

As the solids settle, they slide down the incline plates and collect at the bottom of the clarifier as a sludge layer. The settle solids are periodically remove from the bottom of the tank as sludge. The clarifie water collects at the top of the plates and is collect for further treatment or discharge.

System Components

The Lamella Clarifier consists of a series of incline plates or tubes arrange at an angle inside a tank or vessel. The plates are usually made of plastic or metal and are space a short distance apart.The inclined angle of the plates is typically between 45 to 60 degrees.

Significance & Advantages

Increased Settling Surface Area: The incline plates provide a significantly larger settling surface area compar to conventional clarifiers. This allows for a more effective separation of solids from water within a smaller footprint.
Enhanced Particle Settling: The Lamella Clarifier promotes the formation of laminar flow conditions, which minimize turbulence and enhance the settling of suspend particles. The incline plates also prevent the re-entrainment of settle particles into the clarifie water.
Space Efficiency: The compact design of the Lamella Clarifier allows for space savings compare to conventional clarifiers, making it suitable for installations with limit space availability.
Easy Maintenance: The incline plates are typically design for easy cleaning and maintenance. They can be removed or accesse individually, allowing for simple inspection and sludge removal.
