Our Lamella Sedimentation Tank, also known as inclined plate clarifier, is an advanced high-efficiency solid-liquid separation equipment optimized for modern wastewater treatment projects. Different from conventional horizontal sedimentation tanks, this lamella clarifier adopts shallow sedimentation theory and densely arranged inclined plate structures, greatly amplifying the effective settling area within limited space. It is widely used for removing suspended solids, fine particles, floc sludge, and turbidity impurities in municipal sewage and industrial wastewater. With ultra-high clarification efficiency, compact footprint and stable running performance, it effectively reduces water turbidity and SS content, lowers subsequent treatment load, and serves as an ideal upgraded sedimentation solution for space-constrained and high-efficiency water treatment projects worldwide.
Working Principle
The Lamella Sedimentation Tank operates on the shallow layer sedimentation principle and gravity separation mechanism. Wastewater flows evenly through a series of parallel inclined plates inside the tank. Fine suspended particles and sludge settle rapidly on the surface of the inclined plates due to gravity, instead of relying on long-distance settling in traditional tanks. The accumulated sludge slides down the inclined plates to the bottom sludge hopper for centralized collection and automatic discharge. After solid-liquid separation, the purified clear water rises to the upper water outlet and is discharged stably. The unique inclined plate layout shortens particle settling distance and retention time, effectively avoiding particle re-suspension and greatly improving overall sedimentation efficiency compared with conventional sedimentation equipment.
Core Features & Advantages
-
Ultra-high Sedimentation Efficiency: The inclined plate structure multiplies the effective settling area by 8–10 times, enabling fast separation of fine suspended solids that are hard to settle in traditional tanks. It delivers higher clarification accuracy and stable low-turbidity effluent.
-
Ultra-compact Footprint: It only occupies 10%–30% of the floor space of a conventional sedimentation tank with the same treatment capacity. It perfectly solves the problem of limited installation space for new plant construction and old plant capacity expansion.
-
Energy-saving & Low Operating Cost: Short water retention time and efficient hydraulic circulation reduce water delivery power consumption. The fully automatic sludge discharge system minimizes manual intervention, cutting daily operation and maintenance expenses.
-
Anti-clogging & Stable Operation: Optimized plate spacing and water flow design prevent sludge clogging and short-circuit flow. The integral structural design ensures long-term stable operation with low failure rate and strong impact load resistance.
-
Durable & Customizable Structure: Inclined plates adopt high-quality FRP or PP anti-corrosion materials, with acid and alkali resistance and long service life. Tank size, plate angle and treatment capacity can be fully customized according to actual water flow and water quality conditions.
-
Wide Application Compatibility: Adaptable to multiple water treatment scenarios, suitable for both domestic sewage and various complex industrial wastewater, with strong tolerance to fluctuating water quality and flow.
Application Scenarios
Our Lamella Sedimentation Tanks are widely adopted in high-standard water treatment and solid removal projects across industries. Typical applications include municipal sewage primary and secondary sedimentation, industrial wastewater treatment for food & beverage, textile printing, chemical, pharmaceutical, papermaking, mining and metallurgy, construction muddy water treatment, rainwater reuse, and circulating water purification. It can be used as independent clarification equipment or matched with coagulation and flocculation systems, providing efficient and stable pre-treatment support for advanced water treatment and standard discharge.
