Filter Media
Flo Trend® Systems
provides a wide variety of filter media for use in various
dewatering container filters. Filter media is available in
stainless steel, nylon, polyester, polypropylene and various
other materials. Standard mesh sizes (or equivalent mesh sizes)
range from 4 mesh (4750 micron) to 325 mesh (44 micron). Types
of weaves vary from the simple monofilament type square weave
(common to stainless steel wire mesh) to the more intricate
multifilament weaves.
The primary intent for
any filter media is to assist in holding back solids during
the dewatering process, not allowing any solids to pass through.
Selecting the proper mesh size or opening in the filter media
is determined by performing tests on sludge samples.
Types of Filter Media:
- Poly-2000
- Poly-2004
- Poly-2007
- Polypro-40
- 304 Stainless Steel Mesh (316 optional)
- Various Plastic Meshes
- Non-Woven Disposable

Stainless Steel
304 stainless steel (316 stainless steel optional) - bonded wire mesh filter media. Most common mesh count used is either 30 over 12 mesh or 50 over 12 mesh. The 12 mesh backing material gives the filter panel strength and resistance to stretching. Polypropylene bonded edges and support strips add strength to the filter panel. |
|
Applications:
- Can be used in all dewatering applications
Patterns
- Offered in square mesh ratings from 4 to 325 mesh with various backup mesh
|
 |
|
| Non-Woven Disposable Media
Non-Woven Disposable Media - used primary as a disposable filter in applications where filter cake is sticky and permanent screens cannot be washed down after each application. The disposable liner is placed into the Container Filter and secured in place using hangers or hooks. Once the dewatering process is complete, the dewatered waste and filter are disposed of and a new filter is installed. |
|
Applications:
- Projects in which it is not practical to leave any residual waste in the container when dumping the load, i.e. specifically uses in which the dewatering container may be taken in and out of different plants/applications on a regular basis and container must be totally cleaned up each time.
- Uses in which the cake sticks to the reusable filters, i.e., oily, greasy, waxy sludge
- Projects in which the filter media could become contaminated by the sludge being processed
Patterns:
- 70 and 100-mesh equivalent
- Various thicknesses of material are available
-
Disposable
-
Medium drainage rate
