Imagine a metropolis with a population of millions, requiring the daily treatment of millions of tons of domestic wastewater. Using traditional rectangular sedimentation tanks would demand an area equivalent to several football fields. Has land availability become the greatest bottleneck for modern wastewater treatment plants? What if you could meet discharge standards within a significantly smaller footprint?

Urban Expansion vs. Environmental Land Constraints

While traditional wastewater treatment processes are trapped in a vicious cycle of "efficiency vs. footprint," the Lamella Clarifier (Inclined Plate Settler) rewrites the physics of sedimentation. It achieves separation efficiency ten times greater than conventional methods, all within just one-third of the space. Water flows efficiently between the plates, undergoing "accelerated settling → laminar separation → reverse discharge."

Application in Municipal Wastewater Treatment Process

Primary Sedimentation: Lamella-equipped primary settlers remove suspended solids more efficiently than traditional tanks, reducing land use by at least 60% while maximizing treatment capacity within a compact area.

Traditional Primary Tank: 90-minute retention, removes ~50% of suspended solids.

Lamella Primary Tank: 25-minute retention, removes over 65% of suspended solids.

Secondary Sedimentation (Crucial Application): Between the lamella plates, the Reynolds number (Re) is controlled to be < 500, maintaining ideal laminar flow and preventing short-circuiting. The sludge glide angle—achieved through a fixed plate inclination and smooth surface design—enables effective self-cleaning.

Tertiary Treatment: In chemical phosphorus removal mode, the combination of coagulants and the Lamella Clarifier can achieve a phosphorus removal rate exceeding 90%.

Ingenious Integrated Design

YIMEI combines core biological wastewater treatment technology with the Lamella Clarifier into an integrated modular system. This design first achieves core organic matter degradation, followed by precise separation, resulting in optimal operational performance.
