Lamella clarifier description

The DAGYEE Lamella Clarifier is designed to provide low cost, efficient solids removal from a wide range of waste and process liquids. The inclined plate design allows the total gravity settling area to be as much as ten times more than the actual floor space occupied by the clarifier. Integral chemical mixing and flocculation tanks are available, as well as options for enhanced sludge thickening.

Lamella clarifier also called inclined plate sediment tank. It is good at high efficient combined type settling tank; set many dense inclined tube packing in sediment area, to make the suspended impurity in water sediment, water rise flow along inclined tube, the separated sludge down to the tank bottom along the inclined tube by gravity, then discharge it in concentration. Such tank can improve sediment efficiency 60~70%, it can improve treatment capacity 3~5 times in the same area.

The implementation of lamella clarifiers in wastewater treatment is widely recognized due to their numerous advantages, such as their ability to handle high flow rates and their versatility across various industries. They are an essential element in the treatment process, appearing in sectors like municipal sewage treatment, industrial effluent processing, and water recycling. Proper installation and maintenance of lamella clarifiers are crucial for their optimal performance and compliance with environmental regulations. Recent technological advancements have further improved the efficacy of these systems, making them more sustainable and cost-effective solutions for wastewater management.

Lamella clarifier structure and working principle

1. Lamella clarifier structure

A Lamella Clarifier is composed of several key components, each crucial to the efficient separation of solids from liquids in wastewater treatment. The design facilitates a smaller footprint and effective processing in each of the distinct zones.

Inlet Zone

The Inlet Zone is where the wastewater initially enters the clarifier. This area is designed to distribute the flow evenly across the width of the unit, which is essential for the efficient operation of the clarification area. Energy dissipation devices within this zone help in reducing the velocity of the incoming water, minimizing turbulence as it moves to the clarification area.

Clarification Area

In the Clarification Area, sets of inclined plates or lamellae are installed. These plates increase the effective settling area of the unit. As water flows upward between the plates, solids settle onto the plates and slide down due to gravity into the sludge collection zone. The spacing and inclination of the plates are designed to optimize the removal of solids and the flow dynamics.

Sludge Collection Zone

The Sludge Collection Zone is situated beneath the lamellae, where settled solids collect and concentrate. This zone typically includes mechanisms, such as a sludge hopper or conveyors, to periodically remove the accumulated sludge for further treatment or disposal. Efficient sludge removal is critical for maintaining the capacity and effectiveness of the clarifier.

Outlet Zone

Finally, the Outlet Zone is where the clarified water exits the system. This portion typically features launders or weirs that allow the clean water to flow out without disturbing the sedimentation process. The clarified water is often subject to additional treatment processes before being discharged or reused.

2. Lamella clarifier working priciple

The DAGYEE Vertical Clarifier is designed to remove solids from wastewater and other process liquids. The Flash Mix and Flocculation Tanks (optional) allow for the addition of chemicals and polymers that will aid the settling process — adjusting pH to precipitate dissolved solids and/or enhancing the agglomeration of suspended particles into heavier, more settle-able floc. The liquid is fed from these tanks into the clarifier through the inlet chamber, which directs flow into the separation section.

The liquid then enters the lower area of the laminar plates through side slots which distribute it across the entire width of the plates. Particulate settles onto the face of the plates and slides down to the clarifier bottom. The clarified liquid exits the plate sections through weirs at the top of the unit which are designed to develop and control adequate pressure drop, maintaining laminar flow through the plates. The clarified liquid then flows into the effluent chamber and out of the clarifier.

Settled solids collect at the bottom of the pyramid sludge hopper and are removed from the clarifier. A Sludge Thickener (optional) with rake mechanism may be utilized in place of the pyramid hopper when applicable.
The unique, modular design of the DAGYEE Parallel Plate Vertical Clarifier allows for easy removal of individual laminar plate modules from the clarifier for inspection.

Lamella clarifier advantage

Lamella clarifiers present several benefits in wastewater treatment processes.

They are designed to maximize settling efficiency while minimizing the footprint required.

Compact Design: Lamella clarifiers utilize inclined plates, which provide a large effective settling area within a compact unit. This design vastly increases the surface area for sedimentation compared to conventional clarifiers.

High Efficiency: Due to the increased surface area from the inclined plate design, settling is more efficient. Suspended particles are effectively removed, making it suitable even for high-flow applications.

Cost-effectiveness: The efficiency of lamella clarifiers can lead to reduced operational costs. They offer better process performance in a smaller space, leading to potential savings in construction and land costs.

Flexibility: These clarifiers can be used in various settings, including both traditional and parallel treatment trains, in new or existing wastewater facilities.

Reduced Sludge Volume: An efficient solid-liquid separation results in less sludge volume, which subsequently reduces the cost associated with sludge handling and disposal.

Low Maintenance: The simplicity of the lamella design often results in lower maintenance needs. Fewer moving parts equate to less wear and tear, as well as lower operational complexity.

By providing advantages such as a compact footprint, efficient processing, and low maintenance, lamella clarifiers have become a favorable option for many wastewater treatment facilities aiming to improve their solid-liquid separation stages.

Environmental benefits: The efficient separation of solids from liquid in a Lamella Clarifier results in a cleaner effluent, which can reduce the environmental impact of wastewater discharge.

Modular Design: The modular nature of the system facilitates easy expansion, allowing for scalability and adaptability to changing processing requirements.
