Prefabricated Lamella Clarifier Tank Sedimentation Tank With Easy Installation And Low Footprint

The Prefabricated Lamella Clarifier Sedimentation Tank is a high-efficiency, compact solid-liquid separation equipment, specially designed for rapid sedimentation of suspended solids (SS) in sewage and wastewater. It adopts a prefabricated integral structure, combined with the lamella inclined plate technology, which effectively solves the problems of large footprint, complex installation, and low sedimentation efficiency of traditional sedimentation tanks. Widely used in domestic sewage, industrial wastewater (petrochemical, food, textile, mining, etc.), rural sewage treatment, and water purification projects, it is an ideal supporting equipment for small and medium-sized sewage treatment systems, especially suitable for scenarios with limited land and urgent construction needs.

• Full prefabrication: The entire tank body, lamella plates, water distribution system, sludge discharge device, and overflow structure are pre-integrated and factory-assembled, tested, and debugged. No on-site pouring or complex assembly is required.
• Rapid on-site deployment: The prefabricated tank body is made of corrosion-resistant materials (FRP, stainless steel, or carbon steel with anti-corrosion coating), which can be directly hoisted in place. It only needs simple connection of inlet and outlet pipes and power supply, and can be put into trial operation within 1-3 days, greatly shortening the construction period compared with traditional cast-in-place sedimentation tanks (which take weeks or even months).
• No professional construction team required: The installation process is simple, and ordinary construction personnel can complete the operation according to the manual, reducing construction costs and technical thresholds.

• Lamella inclined plate technology: The tank is equipped with a large number of parallel inclined lamella plates (inclination angle 60°), which divide the sedimentation space into multiple small layers, increasing the effective sedimentation area by 3-5 times compared with traditional horizontal flow sedimentation tanks.
• Compact structure: Under the same treatment capacity, the footprint of the prefabricated lamella clarifier is only 1/3-1/5 of that of traditional sedimentation tanks, which is especially suitable for urban areas, industrial parks, rural areas, and other scenarios with limited land resources.
• Vertical design optional: It can be designed as a vertical structure according to the on-site space, further saving horizontal land occupation and adapting to narrow installation environments.

• Rapid solid-liquid separation: The lamella plates shorten the sedimentation distance of suspended solids, reduce the sedimentation time (from 1-2 hours of traditional tanks to 30-60 minutes), and the SS removal rate can reach 90-98%.
• Stable performance: The uniform water distribution system ensures that the wastewater flows evenly through each lamella plate, avoiding short-circuit flow and improving the overall sedimentation effect; the sludge is concentrated at the bottom of the tank and discharged regularly through the automatic sludge discharge device, ensuring stable effluent quality.
• Strong impact resistance: It can adapt to the fluctuation of inlet water quality and water volume, and still maintain good sedimentation effect when the SS concentration of inlet water changes within a certain range.

• Corrosion-resistant materials: The tank body and lamella plates are made of FRP (fiberglass reinforced plastic), 304/316 stainless steel, or carbon steel with epoxy anti-corrosion coating, which are resistant to acid, alkali, and sewage corrosion, with a service life of 15-20 years.
• Simple maintenance: The lamella plates are detachable and easy to clean; the automatic sludge discharge device runs stably, requiring no frequent manual operation; the overall structure has no easily damaged parts, reducing maintenance costs and workload.

• Modular design: Multiple prefabricated units can be combined in parallel to meet the treatment needs of different water volumes (from 5m³/day to 500m³/day).
• Customizable parameters: The size of the tank body, the number of lamella plates, the material, and the sludge discharge method can be customized according to the actual water quality (SS content, particle size), water volume, and on-site space.
• Wide compatibility: It can be used independently as a sedimentation unit, or combined with格栅 (grille), regulating tank, biochemical treatment unit, disinfection unit, etc., to form a complete sewage treatment system.

• Domestic sewage treatment: Rural areas, residential communities, small towns, and other places without complete sewage pipe networks.
• Industrial wastewater pretreatment/advanced treatment: Petrochemical, food processing, textile printing and dyeing, mining, electroplating, and other industries, used to remove suspended solids in wastewater.
• Water purification: Surface water (river water, lake water) purification, removing sediment and suspended solids in raw water.
• Temporary scenarios: Construction sites, temporary camps, emergency disaster relief, and other temporary sewage treatment needs.
• Supporting equipment: Movable containerized sewage treatment systems, small and medium-sized sewage treatment stations, etc.

Compared with traditional sedimentation tanks, the prefabricated lamella clarifier sedimentation tank has obvious advantages: easy installation, short construction period, small footprint, high sedimentation efficiency, stable effluent, durability, and low maintenance. It effectively solves the pain points of traditional sedimentation tanks such as complex construction, long cycle, large land occupation, and high maintenance cost, and is a cost-effective, efficient, and practical solid-liquid separation equipment for modern sewage treatment projects.
