High-rate Thickener

High-rate Thickener which is manufactured by EPIC is a high-performance slurry clarification and concentration solution, exported globally with a reputation for reliability and efficiency. This thickener is designed to reduce equipment footprint while maximizing sedimentation rate and underflow concentration through chemical-assisted flocculation and deep bed compression. Its innovative design ensures smooth slurry distribution, prevents short-circuiting, and improves processing capacity compared to traditional thickeners.

Core Features & Advantages

1. Treatment Flux Excellence – Modern High-Efficiency Standard

· Units achieve exceptional processing per square meter, significantly surpassing conventional thickeners.

· Recognized as a “modern high-efficiency plant standard” for mining, metallurgy, and chemical operations.

2. Mud Bed Filtration Technology – Patented Feedwell Mixing

· Feed slurry is evenly distributed through a specially designed feedwell, preventing turbulence.

· Slurry passes through the dense mud bed, performing self-filtration and ensuring clear overflow water.

· Enhances overall underflow quality and reduces downstream water treatment costs.

3. Deep Compression Design – Higher Solids Concentration

· Deep tank and sludge bed of High-rate Thickener create static pressure that compresses sediments.

· Produces higher-density underflow, reducing load on subsequent filtration equipment.

· Improves slurry transport efficiency and reduces chemical usage per ton of solids.

4. Energy & Chemical Efficiency

· Optimized rake and flow design reduce mixing energy and flocculant consumption.

· High underflow density ensures minimal water loss and improved recycling in process circuits.

5. Wide Industrial Application

· Ideal for large-scale modern factories with strict underflow concentration requirements.

· Suitable for mining, metallurgy, chemical, building materials, and environmental sectors.

Working Principle

The High-rate Thickener operates through a combination of chemical-assisted flocculation, deep bed compression, and mechanical scrapers:

1. Slurry enters through a feed sleeve equipped with a feed tray to evenly distribute the material and prevent turbulence caused by residual feeding pressure.

2. The internal flow weir guides the slurry along the designated stroke for uniform distribution.

3. Flocculants accelerate sedimentation, forming a dense mud bed that acts as a natural filter, separating solids from liquid.

4. The rake mechanism, with its optimized curved teeth, scrapes concentrated underflow efficiently to the discharge point.

5. Gas bubbles are eliminated in the degassing tank to prevent frothing, ensuring consistent overflow water quality.

This combination allows the thickener to achieve higher underflow density and processing capacity with smaller equipment dimensions.
