UP-FLOTM FILTER OPERATION AND MA1NTENANCE MANUAL [\~aintenance OVERViEVV 111c Up-Flo"\! Filter protects the environment by removing a \.vide range of pollutants from storm water runoff. Periodic removal of these capt'urcd pollutants is essential to the proper functioning of the Up-Flor.\! Filter. The Up-Flo'''\ Filter design allows for easy and sare inspection, monitoring and clean-out procedures. The Up-Flo,.\1 Filter has a wide central clciJrance for casy and comfortable acccss to the Up- Flo 1.\1 Filter components (see Figure 21. Maintenance events can be categorized as Routine or Annual. Routine maintenance can include inspection, f10atables removal and/or sediment removal. Routine maintenance events do not require entry into the Up-Flol.\) chamber. In the case of inspection and floatables removal, a vactor truck is not required. However, a V<:1ctor truck is required if the maintenance event is to include sediment removal from the sump of the Up-Flo"\\ vessel. Annual maintenance includes Media Pack rcpl<:1cemcnt in addition to sediment and f10atables removal. In most instances, entry into the Up-Flo 1.\\ vessel is requ ired for Media Pack replacement. 111ere is the need to follow OSHA Confined Space Entry procedures when performing annual maintenance. DETERMINiNG YOUR MAINTENANCE SCHEDULE The frequency of maintenance procedures can be determined in the field after installation. Hydro International, however, recommends that routine maintenance be completed at least every six months during the first year of operation. Typically, annual maintenance is recommended once per year. During the first year of operation, the unit should be inspected every six months to determine the rate of sediment and floalables accumulation. To prevent from blocking the entryway to the filter media, the sediment must be removed before it completely fills the slimp. A simple probe, such as the Sludge-Judgei' can be used to determine the level of solids in the sediment storage faCility. This information can be recorded in maintenance logs to esrablish a routine maintenance schedule. Pollutant storage volume vvill be dependent on the sump depth of the Up-FloT.\, Filter. A typical 4-tt round manhole Up-FiaT." Filter has 0.6 yeP of sediment storage. Routine and Annual maintenance procedures for <:1 typical 4-ft diameter manhole Up-Flo!.\\ Filter take less than 30 minutes and removes about 360 gallons of W<:1tcr in the process. Spent Media Bags weigh about 40 Ibs. Spent Medi<l Packs should be disposed of at your local landfill. / / I Figure 2: The wide clearance jJl lhe up-noTM ntler ROUTiNE MAINTENANCE PROCEDURE INSPECTION Inspection is <l simple process that does not involve entry into the Up-Fln!.\\ chamber. Maintenance crews should be familiar with the Up-FloT.\\ Filter and its components prior to inspection.
