Tube Settler
Media

Hexagonal honeycomb and lamella inclined-tube media for sedimentation and desanding — Φ25/35/50/60/80/90mm in PP, FRP and stainless steel. Its large wetted perimeter and small hydraulic radius keep flow laminar, so particles settle undisturbed and handling capacity rises to several times that of a flat basin.

Why this media

Handles more, settles faster

The inclined-tube geometry creates laminar flow with a large wetted perimeter, so solids drop out undisturbed at a far higher hydraulic load.

Laminar, undisturbed settling

Large wetted perimeter and small hydraulic radius keep flow laminar, so particles settle without turbulence interference.

Up to 5x the handling capacity

At V₀ 2.5–3.0 mm/s and a load of 3–5 t/m²·h, handling is roughly 3–5× a flat settler and 2–3× a shallow tank.

Multiple materials, long life

Available in PP, FRP and stainless steel; co-polymer based media can extend service to 8–10 years in water.

Structure & characteristics

Built for efficient, stable settling

Hexagonal honeycomb and lamella inclined-tube media assembled from straight hexagonal tubes, available with inclined or straight passages in PP, PVC, co-polymer or FRP.

Honeycomb cells

Straight hexagonal tubes form the honeycomb body — PP, PVC, co-polymer or FRP, in inclined or straight-tube form.

High surface, smooth walls

Surface area 133–360 m²/m³, porosity 97–98%, smooth tube walls and stack height 4–5 m.

Lamella (inclined) type

Co-polymer plastic lamella boards — Φ35/50/80mm, high toughness and assembly strength, long aging life.

COD removal 85–90%Organic load 2000–5000 g/m³·dSand load 50–100 kg/m²BOD ~128 g per tonne·day
