We have recently delivered and completed the installation of Tube Modules for a Lamella Clarifier originally built in 1991. The clarifier handles wastewater produced by a Combined Heat & Power plant. We delivered the Tube Modules on the agreed date and installed them a day early, therefore allowing the clarifier to be finally put back into service a little earlier than anticipated.

Advantages of Tube Modules

You really can improve the efficiency of solids settlement in a Lamella Clarifier by using our Tube modules. They:

  • Ensure laminar flow across the whole surface area of the tank, therefore avoiding local areas of high upward velocity which would prevent efficient settlement.
  • Increase the effective area for solids settlement, typically by 8:1
  • Allow small solids that do not settle easily to flocculate with each other, after which they then settle.
  • Minimise the floor area that you need to allocate for settlement

Over 40 years of use has proven the efficiency of H+E’s Tube Modules. Many hundreds of plants across Europe use them.

Strong and Long-lasting

Each tube within the modular pack is inclined at 60°. Each row or tube is inclined in the opposite direction to its neighbour rows. Consequently, flow distribution across the tank is good and also makes the Tube Modules strong.

They are fabricated in ABS. This ensures they are light, hence easily lifted by two people, and have a long service life.

The tubes themselves have a square cross-section. Solids do not easily get trapped within the tubes because there are no “tight” angles. Consequently their operating efficiency is maintained for the long-term.

Tube modules are often retro-fitted into existing clarifiers, therefore increasing their operational efficiency.

Applications

In more or less every application where high efficiency settlement of solids is required, tube modules are an appropriate solution.
