GENERAL DESCRIPTION
The PEP SMF-FG Series Industrial Water Filters are permanent media type units specifically
designed to clean industrial and process water. The PEP SMF-FG filters are designed for
side-stream or in-line applications on non-pressurized systems. The SMF-FG filter vessel is
constructed of fiberglass reinforced thermoplastic and has a pressure rating of 50 psig (350
kPa).
FILTER OPERATION
Water from the system is pumped through the over-drain assembly at the top of the filter
tank and distributed evenly over the media. Suspended particles are trapped in the filter
media. The filtered water then passes from the vessel through the under-drain assembly
at the bottom of the filter and returns to the system.
When the trapped particles cause the pressure differential across the media bed to reach a
pre-determined pressure of approximately 10 PSIG (69 kPa) over starting gauge pressure,
the valves are automatically or manually repositioned and the media is backwashed. The
media is backwashed with a rigorous scouring action and the trapped particles are
released. The dirty water passes from the filter tank through the over-drain assembly at
the top of the vessel and is flushed to the drain. When the media is cleaned after a preset
time (2 minutes standard), the valves are again repositioned and the filtration cycle is
continued.
INSTALLATION
UNPACKING
When the PEP Industrial Water Filter is delivered to the jobsite, it should be checked
thoroughly to ensure that all required items have been received and the filter equipment is
free of any shipping damage prior to signing the bill of lading.
The model number of the filter will appear on a nameplate located on the unit and should
be checked against the invoice/packing list. Table 1 shows the parts that should be
inspected when the unit is unpacked.
RIGGING
1. PEP SMF-FG units should be lifted with a forklift or overhead crane. If these units are
lifted with an overhead crane, lifting straps must be located below the filter skid and
should not come in contact with the filter components.
