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