UP-FLOTM FILTER OPERATION AND MAINTENANCE MANUAL Maintenance OVERVIEVV The Up-Flol.\\ Filter protects the environment by removing a wide range of pollutants from stornwvater runoff. Periodic removal of these captured pollutants is essential to the proper functioning of the Up_FloT.\l Filter. The Up-Flo!.\\ Filter design allows for easy and safe inspection, monitoring and clean-out procedures. The Up-Flol;" Filter has a wide central clearance for easy and comfortable access to the Up- Flo!.\\ 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-Flor.\) chamber. In the case of inspection and floatables removal, a vactor truck is not required. However, a vactor truck is required if the maintenance event is to include sediment removal from the sump of the Up-Flol~' vessel. AnnuJI maintenance includes Media Pack replacement in addition to sediment and f10atables removal. In most instances, entry into the Up-FIJ'~' vessel is required 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 recoll1mended once per }fear. During the first year of operation, the unit should be inspected every six months to determine the rate of sediment and floatables 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-Judge' can be used to determine the level of solids in the sediment storage facility. This information can be recorded in maintenance Jogs to establish a routine mJintenance schedule. Pollutant storage volume vvill be dependent on the sump depth of the Up-FloT.\, Filter. A typical 4-ft round manhole Up-Flo"\\ Filter has 0.6 ycJl of sediment storage. Routine and Annual maintenance procedures for a typical 4-ft diameter manhole Up-Flo!.\1 Filter take less than 30 minutes and removes about 360 gallons of vvater in the process. Spent Media Bags weigh about 40 Ibs. Spent MediJ P;)cks should be disposed of at your locallandfj[l.

Maintenance crews should be familiar \-\lith the Up-FloT.\l Filter and its components prior to inspection. SCHEDULING .
