# Lamella Clarifiers

High-rate settling in a fraction of a conventional clarifier's footprint.

A lamella clarifier is a settling tank fitted with inclined plates or tubes that greatly increase the effective settling area within a small footprint. It is used in industrial wastewater treatment, drinking water treatment, mining and metal finishing wherever suspended solids must be separated by gravity in limited space.

## How it works

Wastewater, often pre-treated with coagulant and flocculant, enters the clarifier and flows upward between closely spaced plates or tubes set at a steep angle, typically around 55 to 60 degrees. Particles only need to settle a short distance before reaching a plate surface. The settled solids then slide down the inclined surfaces into a sludge hopper at the base, from where they are removed for thickening or dewatering. Clarified water rises above the plate pack and leaves through overflow weirs or launders. Because the projected settling area of all plates adds together, the clarifier achieves high capacity in a compact tank.

## Models

- [Lamella Plate Clarifier](https://www.waste-water-equipment-factory.com/products/lamella-clarifiers/lamella-plate-clarifier/): This industrial lamellar clarifier separates suspended solids from wastewater using stacked inclined plates that provide a large settling area in a compact tank. It is supplied with field installation, commissioning and training. It suits factories and treatment plants that need higher clarification capacity without the footprint of a conventional sedimentation basin.
- [Inclined-Tube Settler, 1–300 m³/h](https://www.waste-water-equipment-factory.com/products/lamella-clarifiers/inclined-tube-settler/): This inclined tube sedimentation tank is a lamellar clarifier for sewage and wastewater treatment. Inclined tubes create a large settling area, allowing solids to settle in a compact tank across a capacity range of 1–300 m³/hour. It is available in carbon steel or stainless steel for municipal and industrial plants that need efficient clarification with limited space.

## How to choose

- **Flow rate and surface loading:** Size the unit on design flow and the projected plate area needed for the settling velocity of the particles. Settling tests on the actual wastewater give the most reliable basis.
- **Solids characteristics:** Floc size, density and concentration affect plate spacing and hopper design. Sticky or fibrous solids may need wider spacing to avoid blockage.
- **Chemical pretreatment:** Many applications need coagulation and flocculation ahead of the clarifier. An integrated flash mix and flocculation tank simplifies installation.
- **Plates or tubes:** Inclined plates are robust and easy to clean, while tube settlers are lightweight and often used to upgrade existing tanks.
- **Sludge handling:** Consider hopper volume, sludge withdrawal method and whether a thickener or dewatering machine will follow.

## Applications

- Industrial wastewater clarification
- Drinking and process water treatment
- Metal finishing and electroplating effluent
- Mining and quarry wash water
- Stone cutting and ceramic wastewater
- Upgrading existing sedimentation tanks
- Filter backwash water recovery

## FAQ

### Why is a lamella clarifier smaller than a conventional clarifier?

The inclined plates stack many settling surfaces in one tank, so the effective settling area is much larger than the tank's floor area. This allows the same separation in a smaller footprint.

### What angle are lamella plates set at?

Plates or tubes are typically inclined at around 55 to 60 degrees. This angle is steep enough for settled solids to slide down by gravity into the hopper.

### Do lamella clarifiers need chemicals?

Many applications use coagulant and flocculant to form larger, faster-settling flocs. Wastewater with heavy, granular solids may settle without chemicals.

### How are lamella plates cleaned?

Plates are usually cleaned periodically with a water spray or by draining the tank. Proper chemical dosing and regular sludge withdrawal help reduce buildup.
