| McTIGHE PETRO PAK DESCRIPTION
SHEET |
| |
| To stay a step ahead of Environmental
Protection Agency wastewater discharge requirements, McTighe engineers
lead the way with not only utilizing a high performance, low maintenance
corrugated plate arrangement, but also including a secondary oleophilic
(oil attracting) and hydrophobic (water repelling) coalescer. The
McTighe Petro Pak* is an enhanced coalescer specifically designed
to intercept oil droplets down to 20 microns in size. The McTighe
Petro Pak* is not a filter and does not need to be frequently disposed
and replaced. |
| |
| The Petro Pak* is made up of multiple
layers of coalescing media arranged from course to fine. The media
consists of a matrix of interlaced monofilament strands. The multi-monofilament
design is such that each monofilament is perpendicular to the fluid
flow and also perpendicular to each monofilament. The media is enclosed
in a 304 stainless steel frame. All the Paks in the McTighe separator
are provided with lifting hooks and are housed in steel channels
for easy removal and reinstallation. |
| |
| The standard material of construction
of our Petro Pak* coalescing media is polypropylene. With routine
maintenance, the Petro Pak* has an estimated life of 10-15 years
and can operate at influent temperatures of 40o to 160o F and over
a pH range of 2 to 12. Petro Pak* media constructed of Kynar* and
Teflon* are available for extremely corrosive and/or high temperature
requirements. |
| |
| The Pak is designed to be self-unloading
to minimize maintenance requirements. Once attached to the polypropylene
strands, oil globules agglomerate and either wick-up or, if sufficiently
large, break away and rise to the surface. After reaching the surface,
the separated oil will spread out and form a layer allowing unrestricted
flow conditions. |

|
Maintenance:
|
| |
| Before removal of the Petro Pak*,
it is a good practice to remove accumulated oil from the separation
chamber. Typically, the Pak is maintained during routine separator
maintenance and the oil removal is a part of that requirement. The
Petro Pak* can be easily removed and reinstalled by removing the
access cover and pulling the Pak out by the use of its lifting arm.
Wash down the coalescing media with water pressure (about 35 psi).
Be careful not to use steam cleaning unless the Petro Pak* media
is rated for the steam temperature. The media can be removed from
the stainless steel framework to aid in cleaning operations. Suspended
solids and debris constitute the main contaminants that need to
be cleaned from the Pak. |
| |
|
After cleaning, reinsert the Pak
into the channels with the fine mesh side of the Petro Pak* facing
the discharge (effluent) end of the separator. Fill separator
with water to maximum capacity. Separator is again ready for operation.
