Installation Instructions |
- Secure and place
proper traffic safety barriers around site to
prevent
unauthorized traffic in work area.
- Use proper safety
equipment and procedures when removing and
replacing grates and installing and servicing
filters.
- Clear work area and
remove grate.
- Confirm measurements
of filter and catch basin.
Clean catch basin if necessary.
- Place filtration unit
in the catch basin.
- Caulk with food grade
silicone around metal frame to prevent water from
bypassing system.
- Install Media in
filter housing.
- Record data of
system/filter installation on tag
Replace grate
- On curb inlets,
install deflector devices.

| General |
| Timely
change-out of the filter media is necessary to keep the
media from becoming saturated. Upon saturation,
pollutants will freely pass through the filter system.
The following information is provided for the user to
establish an maintenance program. Depending on site
specific needs, units may require more frequent change
outs. |
| There
are two types of systems, one with sediment chambers and
one without sediment chambers. |
| A site that
does not have moving sediments, leaves or debris, or are
too small for sediment chambers are candidates for
standard flow-through units. |
| For outside
locations, sediment chambers are highly recommended. |
| Unit
maintenance consists of the following two activities: |
| |
1)
Removal of trapped solids, debris and foreign
matter is necessary
to prevent flow restrictions
and blockage.
2) Media replacement prior to saturation by
pollutants. |
|
| Flow
Restrictions & Blockage |
| Filter
flow rates are reduced when, sediments such as silt and
sand, collesct without maintenance in the treatment
chamber. Blockage may also occur when leaves and debris
enter the filter chamber. |
| Sediment
Removal |
|
Sediment chambers may be vacuumed clean with an 8"
or smaller hose. This should be performed when the
sediment levels approach the transition flow ports. |
| Debris
Removal |
| Debris
screens prevent leaves, grass clippings, etc. from
entering the filtration and sedimentation chambers.
These screens should be cleaned as required to keep an
unobstructed flow through the filtration media. |
| Media
Replacement |
| Use
one of the following methods to determine when to
replace your filter media. |
| Water
Sampling |
| Water
sampling is the most positive indicator of media
performance. Change the media when effluent contaminant
levels approach regulatory and/or predetermined
concentration discharge limits. |
| Visual
Inspection |
| As the
media becomes saturated with hydrocarbons, the Sorb-44
media changes color. The absorbent bags may be removed
and inspected for color change. |
| Calendar
Based |
| Filter
saturation is dependent on the volume of contaminants
removed. For normal road and parking lot applications,
changing media every 4 months should be satisfactory. |
| Electronic
Monitoring |
|
Certain pollutants may be monitored electronically.
Electronic monitors may be tied to alarm centers, such
as an EBW or EMCO Electronics sensor monitor. |
| When
filter discharges exceed alarm threshold settings the
media should be changed. |
