2. Working principle
The polluted water passes the filter fleece and enters into the drum. From here it flows back into the
filter sump. If the fleece is loaded with dirt, the flow through the fleece decreases and the water level
outside of the drum rises. If it reaches a certain level, a level switch starts the motor, the drum
rotates and a small part of fresh fleece is loaded on the drum. Fully automatically. It will take 4 – 6
months, depending on the waste production in the system until the complete fleece is used and has
to be replaced.
The Fleece is very fine. Even smallest
particles are removed. The dirt is filtered out
of the system, before it is metabolized
biologically. This relieves the biofilter and the
protein skimmer in seawater.
The pores of the fleece are even fine enough
to retain many protozoa, like fish parasites in
fresh and saltwater. They cannot pass the
fleece. This is unique.
