Filament fibres can be back-washed fully automatically
Removes the smallest particles for safe pre-filtration
A new class in size and filtration performance

An Innovation in Filtration
WATER PURIFICATION SYSTEM is a patented filter equipped with a special synthetic fibre. It is the first selfcleaning, back-washable fine filter for all filtration challenges up to a size of approx. 1 μm.
The FilaTwist is ideal as a pre-filter for all membrane filtration processes. Due to its fully automatic control system, it functions without operating personnel.

The FilaTwist is light and compact and thus very mobile and quickly ready for operation.
Its light-weight construction, its capability of 24 hour continuous operation and its high filtration capacity make the FilaTwist superior to conventional filters. The FilaTwist can be back-washed during operation and thereby sets a new standard in comparison with bag
or micro filtration systems.

Filament fibres are twisted against each other forming a filter through which dirty water is cleaned. For back-washing, the filter fibres
are loosened and rinsed.
A new filter is created by the fibres.
The recurring self-cleaning process guarantees a long operating time of the filter element.
