of particulate matter in the gravel bed, the gravel is continuously
cleaned in a pneumatic system developed specifically for the EFB system.
At the same time the cleaned gravel is transported to the top of the
system to be used again in the filter.
Collected dust is conveyed in dry, low pressure, low temperature air to a silo or bunker equipped with a small dust collector. This can be located practically anywhere in the plant, usually where other waste materials are deposited. No other conveying systems are needed.
