The endless belt filter
is suitable to handle high dirt loads. A big advantage is that the contamination
is separated in a dry form, with a very low flushing water consumption.
WORKING PRINCIPLE
The liquid flows into
the filter over a dispenser.
The filter belt is guided over th bottom of the filter. The liquid flows through
the filtercloth by gravity, leaving the contamination on it. After some time
the belt will get clogged and the liquid level raises.
Now the belt is transported over a small distance, while a knife scrapes the
filtercake from the belt. A part of the belt is above the liquid level, so the
cake dewaters.
After the scraper spraying clean the filter belt additionally; the flushing water goes back into the filter.
The capacity depends on the kind of dirt, the quantity, filtration rate and dimensions of the belt.
