Types of Lanhai Sedimentation Tanks
Sedimentation tanks are classified by water flow direction into horizontal flow, vertical flow, radial flow, and inclined plate sedimentation tanks.
By application and process, they are categorized as primary sedimentation tanks, secondary sedimentation tanks, and sludge thickening tanks.
The above figure shows the Lanhai bridge sludge thickener. Its underwater components are made of stainless steel, while the above-water parts are constructed from carbon steel. The upper section includes scum scraping plates, working bridge, and drive unit, with sludge scraping plates installed at the bottom. This thickener operates stably, ensuring thorough sludge discharge without dead zones, uniform water distribution, and excellent sedimentation performance.
The vertical flow sedimentation tank depicted above is Lanhai Environmental Technology Co., Ltd. installation at a paper mill. With dimensions of Φ9m × 15m and stainless steel structure, it achieves a suspended solids (SS) removal rate of 90% and COD removal rate of up to 50%.
Features:
No power equipment such as mechanical sludge scrapers or sludge pumps required, resulting in zero energy consumption;
Automatic sludge discharge for simplified operation and easy management;
Space-saving design with a small footprint.

Key Features:
Optimized drive unit for higher efficiency and sleek appearance. Configurable with imported reducers or shaft-mounted reducers as per customer requirements, ensuring enhanced durability and aesthetics;
Large treatment capacity and excellent sludge collection efficiency;
Compact structure, small footprint, and convenient operation and maintenance;
Stable operation with simultaneous sludge and scum scraping, and low energy consumption.
Features of Lanhai Inclined Tube Sedimentation Equipment:
(1) High efficiency: When influent turbidity exceeds 30 NTU, effluent turbidity is reduced to less than 3 NTU;
(2) Suspended solids removal rate reaches over 90%, with exceptional performance for particles larger than 0.05mm;
(3) Enables unattended, automatic operation;
(4) Saves over 40% in footprint and operating costs compared to traditional sedimentation methods.
