Hydrotech Drumfilters type HDF

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

► The liquid is filtered through the periphery of the slowly rotating drum. Assisted by the filter panels special cell structure, the particles are carefully separated from the liquid. Separated solids are rinsed off the filter cloth into the solids collection trough and discharged.

► Careful handling of the solids to prevent fragmentation is in many applications essential to achieve high filtration efficiency. Hydrotech's unique design of the filter panels makes this possible.

Hydrotech's unique filter panels greatly simplify both the replacement and change out of the filter opening size.

The drum is constructed in sections, each with up to 6 filter panels depending on diameter. The filter areas from 0,35 m2 for the HDF501 to 22,5 m2 for the HDF2010 cover a range from 2 to < 1000 l/s (< 3600 m3/h). In total there are 23 different drum filter sizes.

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