The Vertical Pressure Leaf Filter, Description Vertical Pressure Leaf Filters are quite similar to the Horizontal Plate Filters except for the orientation of the filter elements which are vertical rather than horizontal They are applied for the polishing slurries with very low solids content of 1-5% or for cake filtration with a ,Pressure Filter, The backwashing of such filters is very similar to that of an open rapid gravity filter A bellmouth and pipe can be used for the removal of dirty washwater in a vertical filter; for most horizontal filters a single vertical plate located near to one of the dished ends facilitates washwater removal, but for the larger filters, a central washout channel formed by two vertical plates is necessaryCHAPTER 4 DRAINAGE DESIGN, EXAMPLE: If a road culvert is to last 25 years with a 40% chance of failure during the design life, it should be designed for a 49-year peak flow event (ie, 49-year recurrence interval) When streamflow records are not available, peak discharge can be estimated by the "rational" method or formula and is recommended for use on channels draining less than 80 hectares (200 acres):Vertical Pressure Filters, Vertical pressure filters provide granular media treatment in an enclosed pressure vessel Multiple vessels can be used to allow operating flexibility and backwashing from in-service cells Under 1 MGD (4 MLD), they are more economical than horizontal pressure filters Vertical pressure filters are typically applied in small to medium sized plantsMultigrade Filter (MGF), A latest concept in the water treatment technology, a Multi Grade Filter consists of vertical or horizontal pressure sand filters that contain multiple layers of coarse and fine sand (pebbles and gravels) in a fixed proportion It is a kind of a deep filter bed with adequate pore dimensions for retaining both large and small suspended solids ,.
