DBF filtration operates by collecting impurities on the surface of the filter cloth through which the contaminated liquid flows. The filter cloth is unwound from a supply reel and deposited on a driving mesh belt. The filter cloth is pressed against the belt by a pair of squeeze rollers, which at the same time prevent leakage of liquid outside the filter. Liquid impurities settle on the filter cloth and form a sludge layer called filter cake (FC).<a href=\"https:\/\/www.astos.cz\/wp-content\/uploads\/2019\/09\/Bubnova-filtrace-1-e1572438364214.jpg\" rel=\"lightbox[4778]\"><img class=\"aligncenter size-full wp-image-8643\" src=\"https:\/\/www.astos.cz\/wp-content\/uploads\/2019\/09\/Bubnova-filtrace-1-e1572438364214.jpg\" alt=\"Bubnova-filtrace\" width=\"472\" height=\"265\" \/><\/a><strong>Advantages of DBF:<\/strong><\/p>\n<ul>\n<li>Gradual saturation of the pores of the filter cloth and thickening of the impurities also trap particles of a smaller size than the pores of the filter cloth.<\/li>\n<li>When the FC is so saturated that liquid is no longer able to flow through, the level in the vessel increases. This increases the hydrostatic pressure and causes additional liquid to pass through the filter cloth. As soon as FC becomes completely impermeable, the liquid level increases to the extent that it switches the level switch, which triggers the movement of the mesh belt and this automatically feeds the required amount of clean filter cloth. This restores the flow of liquid and creates a new FC. The contaminated cloth with FC is ejected from the DBF and falls into the waste container.<\/li>\n<li>The cloth supply reel is scanned by the reel sensor.<\/li>\n<li>The device can be equipped with a wiper blade to clean the filter cloth of coarse dirt.<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div><div id=\"pg-4778-1\"  class=\"panel-grid panel-no-style\" ><div id=\"pgc-4778-1-0\"
