TUBEdek^®

TUBEdek tube settlers are individual V-shaped plastic profiles built into channels. This design optimizes lamella flow to offer a significant increase in solids settling, reducing both footprint and costs for drinking water and wastewater applications.

TUBEdek is unique in its versatility and can be used in any configuration. It can be adapted to different situations by variation of inclination, length of tubes, and module sizes.

These individual designs support a better process and allow plants to reap cost savings. Due to its high process efficiency and ability to meet tight discharge consents, it is particularly suited for higher effluent flows and loads.

Benefits

Enhanced separation process improves solids discharge

Mechanical strength simplifies installation and maintenance

Reduced tank footprint minimizes space and cost

High quality standards and materials enables long and reliable service life

Navigate Within Tube Settlers & Lamella

Module Features

Tongue and Groove Connections

Unique interlocking profile with tongue and groove connections promotes laminar flow.

Hydraulic Parameters

Advantageous hydraulic parameters achieve process efficiency (Reynolds number).

V-Shaped Settling Planes

Multiple equidistant settling planes in a V-shape improve the discharge of solids (Hazen approach).

Complementary Components

Support System

SKR Sedimentation Tank

AccuGrid^® Surface Grating

Support System

GRP TUBEdek supports are specially-adapted to TUBEdek modules. These support systems minimize turbulence and sludge buildup. GRP beams are positioned under the side walls of settling troughs. Two beams are usually sufficient for a module width up to 1.4m.

SKR Sedimentation Tank

SKR sedimentation tanks offer ready-to-connect units for the sedimentation of solids by the outstanding sedimentation properties of TUBEdek lamella clarifiers.

AccuGrid^® Surface Grating

Installed on top of tube settler modules, AccuGrid interlocking panels provide a protective layer from foot traffic, hydraulic impact, and UV degradation.

Featured Installations

Atotonilco, Hidalgo, Mexico

Application

Mexico’s largest wastewater treatment plant sought to reduce incoming TSS concentrations during primary treatment. TUBEdek’s highly-efficient sedimentation rate minimized the risk of plugging from heavy inflow loads and successfully balanced a monumental effective projected sedimentation area within a small footprint.

Bray, Berkshire, England

Application

South East Water’s Keleher Water Treatment Works was experiencing restricted output with their existing horizontal lamella clarification system. TUBEdek was ultimately selected as the best solution to remove this bottleneck. In addition to successfully improving production capacity, the plant benefits from simple cleaning and maintenance, thanks to TUBEdek’s tongue and groove design.
