Abstract
Dust filter equipment includes a fibrous mat filter (37) having a low fibre density and a low loft so that when water is fed onto the filter it saturates the filter throughout its thickness and flows freely down the filter to form an effectively continuous body of water having a thickness virtually equal to the thickness of the mat filter.
