01 Key Advantages
In a conventional clarifier, a suspended particle must fall the full 2–4 metres of water depth before it's captured. A Juntai tube settler collapses that settling path to the width of a single channel - just 25–80 mm, a 50–160× reduction in settling distance. The engineering breakthrough is holding stable laminar flow (Reynolds number < 500) inside every 60° inclined channel: settled solids slide down the walls by gravity into the sludge hopper while clarified water continues upward - no turbulence, no re-entrainment, no mechanical scrapers. At 60°, each metre of module height projects roughly 0.87 m² of effective settling area, so total effective surface multiplies 6–10× the tank footprint.

15–30 min
HRT from Hours to Minutes
Laminar flow through 60° inclined channels delivers 15–30 min HRT vs 2–4 hr for conventional basins. The 25–80 mm settling path replaces the full 2–4 m water column.
|
85%
Smaller Footprint
Projected settling area multiplied 6–10× by inclined channels. A 1,000 m³/d plant fits in ~8 m² vs ~50 m² for an open basin - same throughput, less than a fifth the space.

2–5 days
Retrofit Without Civil Works
Modular tongue-and-groove panels drop into existing clarifiers. Install in 2–5 days, commission within 72 hours. Zero concrete, zero downtime for adjacent treatment units.
|
30–50%
Less Coagulant
Efficient solids contact in the laminar regime reduces chemical demand vs turbulent open basins. Verified across 500+ installations worldwide - recurring opex savings, not just capex.

04 Tube Settler Diameter Selection Guide
Four channel diameters engineered for specific influent characteristics. The decision rule: higher TSS or fouling risk → larger diameter to prevent clogging; lower TSS → smaller diameter to maximise surface area.

05 Applications
|
Drinking Water Treatment Plants
φ25 mm PP food-grade modules reduce turbidity to <2 NTU ahead of filtration and maintain performance during seasonal high-turbidity events. Compatible with NSF/ANSI 61 requirements.
Primary & Secondary Clarifiers
φ35–50 mm PVC for municipal STPs handling 500–50,000 m³/d. Reduces downstream BOD load on biological stages; retrofit into existing basins for 2–3× capacity gain.
Mining, Chemical, Food & Beverage
φ50–80 mm heavy-duty PVC handles acidic/alkaline effluent, variable TSS loads and shock hydraulic events. Chemical-resistant formulation for aggressive process water.
Retrofit Capacity Expansion
Install modules into current basins - double throughput without a single new concrete pour. 2–5 day installation, zero downtime for adjacent treatment units.
