Hydrotech Drumfilter

The Hydrotech Drumfilter from Veolia Water Technologies is a mechanical and self-cleaning filter that has been specially designed for high performance in systems where it is essential to prevent particles from fragmentation.

This drumfilter technology facilitates the careful handling of solids that prevents fragmentations and therefore achieving high filtration efficiency. The filter works without any pressure and features robust design with few moving parts to ensure longer operating life and lowered maintenance costs.

Features and benefits of our Hydrotech Drumfilters:

  • Self-cleaning filter
  • High filtration efficiency
  • Patented, proven construction
  • Modular, easy-to-maintain designs

Modular construction for simplified maintenance:

Hydrotech's unique filter panels simplify the replacement and change-out of the filter opening size. The specially designed drum is constructed in sections, each with up to 6 filter panels depending on diameter.

  • The filter area ranges from 0.35 m2 (for the HDF501) to 22.5 m2
  • The HDF2010 covers a 2 to < 1 000 l/s (< 3600 m3/h).
  • In total there are 23 different drum filter sizes.

This Modular design facilitates simplified maintenance and makes it easy to adapt the filter to actual need of flow capacity and performance.

How it works:

  1. Water is filtered through the periphery of the drum
  2. Assisted by the filter panels' special cell structure, the particles are carefully separated from the water during backwash
  3. Separated solids are rinsed off the filter cloth into the solids collection trough and discharged
    (Backwash of the filter is only required according the loading of particles)
