Wastewater treatment is a critical process for protecting water resources and maintaining public health. As industries and populations grow, the demand for efficient and compact treatment systems has increased. One of the most effective technologies in primary treatment today is lamella water treatment, also known as lamella clarifier systems. These units use inclined plate settlers to enhance the sedimentation process, significantly improving space efficiency and particle separation.
Our company specializes in manufacturing lamella clarifiers tailored for various wastewater treatment applications. These units provide reliable performance, minimal footprint, and consistent results in removing suspended solids and preparing water for downstream biological or chemical treatment.
Lamella water treatment is a type of physical separation process used in wastewater treatment plants. It uses a series of inclined plates, arranged at a specific angle (usually around 55°), to increase the settling surface area within a compact tank. This design allows suspended particles to settle more efficiently as they slide down the plates into the sludge zone, while clarified water rises between the plates and exits from the top.
Compared to conventional sedimentation tanks, lamella clarifiers provide several times more effective settling area within the same footprint. This makes them ideal for plants with limited space or requiring high-throughput treatment capacity.
A standard lamella clarifier includes the following components:
Inlet feed chamber: Evenly distributes the flow across all lamella plates.
Inclined plate pack: The heart of the system, where solids settle and slide down.
Sludge hopper: Collects settled particles for removal.
Effluent collection trough: Gathers clarified water exiting from the top of the lamella plate section.
Support frame and tank body: Usually made of stainless steel or coated carbon steel for durability and corrosion resistance.
These components work together to provide high sedimentation efficiency in a small and modular unit.
In the wastewater treatment process, lamella systems are typically used during the primary clarification or physical pretreatment stage. Here's how the system operates:
Raw wastewater enters the feed chamber, where flow is evenly distributed.
As water flows upward through the plate pack, suspended solids settle onto the plates.
These particles slide downward due to gravity and collect in the sludge hopper.
Clarified water flows upward between the plates and exits through the collection troughs.
This process significantly reduces the load on secondary treatment systems such as activated sludge or MBBR systems. It also allows chemical flocculation to work more efficiently when added upstream.
Lamella systems offer many advantages compared to traditional sedimentation tanks:
Compact design: Requires 50–80% less footprint than conventional tanks.
High efficiency: Effective in removing particles ≥ 50 microns.
Easy integration: Can be added to existing wastewater treatment plants with minimal modifications.
Modular construction: Scalable for different flow capacities.
Low maintenance: Few moving parts and easy access to components.
Stainless steel options: Resistant to corrosion, ideal for industrial wastewater environments.
These features make lamella systems ideal for industrial, municipal, and commercial wastewater applications where space, performance, and cost-efficiency are critical.
Our lamella clarifier systems are used in many different wastewater treatment scenarios, including:
Municipal treatment plants: As a primary clarifier to reduce TSS and improve downstream biological treatment efficiency.
Petrochemical facilities: For removing solids and chemical precipitates formed during pH adjustment or coagulation.
Food and beverage industry: To reduce organic and suspended solids before dissolved air flotation (DAF) or biological treatment.
Metal finishing and electroplating: Removes heavy metal hydroxide sludges after neutralization.
Paper and pulp mills: Efficiently handles fibrous solids and reduces load on secondary clarifiers.
In each case, lamella clarification improves system throughput and protects sensitive downstream treatment units.
The performance of a lamella water treatment system also depends on the materials used for construction. Our systems are available in:
304/316 stainless steel: Provides excellent corrosion resistance and long service life.
Carbon steel with epoxy coating: Cost-effective option for municipal plants with low chemical exposure.
Polypropylene or PVC plate packs**: Lightweight and chemical-resistant options for non-aggressive applications.
These materials are selected based on your specific influent composition, temperature, and chemical dosing plans. Our team provides full customization based on your plant design.
Lamella clarifiers work well as a pretreatment stage for:
Dissolved air flotation (DAF) systems
Moving bed biofilm reactors (MBBR)
Sludge dewatering equipment
Tertiary filtration or UV disinfection
By removing a large portion of suspended solids early, lamella units reduce chemical demand, energy consumption, and sludge production downstream.
