Cartridge Filter• Cartridge filters can be individual units placed in avault, or a single unit placed in a storm drain inlet.• For proprietary systems like cartridge filters, referto the manufacturer’s instructions for designguidance.Sand Filter• A surface sand filter uses an exposed media bed.Relative to underground sand filters, surface sandfilters can typically treat larger drainage areas andare the easier to maintain.• An underground sand filter is installed belowgrade in a vault. This type of design is preferredwhere space limitations or topography(inadequate hydraulic head) preclude the use of asurface sand filter.• For maintenance of surface sand filters, includeaccess ramps at the inlet and the outlet of thesystem.• Design flow spreaders to minimize turbulence andCartridge based filter installed at a commercial site.spread runoff uniformly across the media bed.Design stone riprap, geotextile fabric, or other energy-dissipation devicesto prevent gouging of the media.• Types of underdrain systems include: a central collector pipe with lateralfeeder pipes; a geotextile drain strip in a drain rock bed; or a collectorpipe in a drain rock bed.• The internal diameter of underdrain pipes should be a minimum of 6inches, with two rows of 0.5 inch diameter holes spaced a maximum of6 inches apart longitudinally. Space rows 120 degrees apart with theholes laid downward. The maximum distance between two lateralfeeder pipes should be 15 feet. All piping should be Schedule 40 PVC,or pipe with greater wall thickness.• Slope the central collector pipe a minimum of 0.5 percent. If the pipewill be subject to freezing, slope the collector pipe a minimum of 1percent.• If drain rock is used, place a geotextile fabric between the sand layerand the drain rock. Drain rock shall be clean, thoroughly washed and¾ to 1 ½ inches in size.• Provide maintenance access to the underdrain piping.• Compose the filter bed of at least 18 inches of clean washed sand (or othermedia selected for use) and placed level. Avoid over compaction to ensureTRPA <strong>BMP</strong> HandbookChapter 4: <strong>BMP</strong> Toolkit2012 4.4.2.5-Media FilterPage 3
adequate filtration capacity. After the sand layer is placed, water settling isrecommended. Flood the sand with 10-15 gallons of water per cubic footof sand.• The table below provides a suggested sand gradation.U.S. Sieve NumberPercent Passing4 95-1008 70-10016 40-9030 25-7550 2-25100
