Up-Flo

Filter Operation and Maintenance Manual

Inspection & Maintenance

Overview

The Up-Flo

Filter protects the environment by removing a wide range of pollutants from stormwater runoff. Periodic removal of these

captured pollutants is essential to the proper functioning of the Up-Flo

Filter.

Maintenance activities can be categorized as those that may be performed from outside the Up-Flo

vessel and those that are performed

inside the vessel. Maintenance performed from outside the vessel includes removal of floatables and oils that have accumulated on the

water surface and removal of sediment from the sump. Maintenance performed inside the vessel includes removal and replacement

of Media Bags, Flow Distribution Media and the Drain Down Filter. A vactor truck is required for removal of oils, water, sediment, and

to completely pump out the vessel to allow for maintenance inside. OSHA Confined Space Entry procedures must be followed when

entering the Up-Flo

vessel.

The Up-Flo

Filter design allows for easy and safe inspection, monitoring and clean-out procedures. It has a wide central opening

between the Filter Modules for easy and comfortable access to all of the components (see Fig.3). Completion of all the maintenance

activities for a typical manhole Up-Flo

Filter takes less than one hour. In the case of inspection and floatables removal, a vactor truck is

not required. Otherwise, a vactor truck is normally required for oil removal, removal of sediment from the sump, and replacement of the

Media Packs and Drain Down Filter. In most cases, entry into the Up-Flo

Filter vessel is required for replacement of the Media Packs

and Drain Down Filter, and OSHA Confined Space Entry procedures will have to be followed.

Filter is installed in a) 4-ft (1.2m) round manholes or b) in rectangular precast vaults. Both configurations have a wide central opening

in the Up-Flo

Filter.

Maintenance activities include inspection, floatables removal, oil removal, sediment removal, Media Pack replacement, and Drain Down

Filter replacement. The minimum required frequency for replacement of the Media Pack is annually, whereas the minimum required

frequency for removal of accumulated sediment from the sump is dependent on the Up-Flo

Filter configuration. Configurations with a

larger sediment storage volume per module will require less frequent removal of accumulated sediment. Regardless, whenever sediment

depth in the sump is found to be greater than 16 inches, sediment removal is required.
