Core points
- Sintered PE/PP cartridges are binder-free: powder is sintered without chemical adhesives, so nothing migrates into the filtrate - the basis of their GMP/FDA food-contact compliance [Lysinterfilters PE cartridge datasheet].
- Certifications cited across the industry include FDA 21 CFR 177.1520, EU 10/2011, RoHS and REACH [Gezifiltech PE cartridge specifications].
- Cleanability is the economic argument: 0.5 MPa gas-liquid backwash or acid/alkali immersion recovers above 90% permeability, with more than 50 reuse cycles reported [NESIA sintered plastic filter data].
- Steam sterilisation is tolerated short-term (to about 130 °C); continuous duty stays at or below 80 °C [Lysinterfilters PE cartridge datasheet].
- Application matrix: pharmaceutical decolourisation and RO pretreatment, beverage clarification, electroplating metal-ion removal, solvent recovery [Lysinterfilters PE cartridge datasheet].
The compliance package, item by item
A regulated buyer needs four documents, and should ask for them before the purchase order: the material declaration (which polymer grade, which additive package), the food-contact certificate (FDA 21 CFR 177.1520 or EU 10/2011), the quality-system certificate (ISO 9001 for the producing plant) and the cleaning/reuse validation note - what the media is certified to survive. Sintered PE/PP is a strong position on all four because the media is a single polymer with no binder to leach [Gezifiltech PE cartridge specifications].
Application matrix
| Pharmaceutical | Decolourisation, RO pretreatment, oral liquid filtration, fermentation broth |
|---|---|
| Food & beverage | Mineral water, beer and liquor terminal filtration, juice clarification, edible oil polishing |
| Water treatment | Heavy-metal removal, desalination pretreatment, electroplating wastewater |
| Chemical | Precision filtration of alum sulphate, hydrogen peroxide, methanol; solvent recovery |
| Regeneration | 0.6 MPa compressed-air backwash or acid/alkali immersion; 50+ cycles reported |
FAQ
What compliance documents come with the cartridge?
FDA food-contact declarations, GMP material compliance, RoHS/REACH and material certifications depending on grade - request them with the quotation.
How many cleaning cycles?
Industry data reports 50+ backwash cycles with above 90% permeability recovery.
Steam sterilisation?
Short exposure to about 130 °C is tolerated; keep continuous duty at or below 80 °C.
Conclusion
For regulated plants, sintered PE/PP cartridges answer the compliance question and the running-cost question at once: certified materials, no binders, and a media you wash instead of throw away. BROLERN supplies the full documentation package with every batch.
FAQ
What compliance documents come with a sintered plastic cartridge?
FDA food-contact material declarations (e.g. FDA 21 CFR 177.1520), GMP material compliance, RoHS/REACH and material certifications, depending on the grade.
How many cleaning cycles does the media survive?
Industry data reports 50+ gas-liquid backwash cycles with permeability recovery above 90% for sintered PE/PP media.
Can the cartridge be steam sterilised?
Short-term exposure is tolerated (up to about 130 C); long-term continuous duty should stay at or below 80 C to avoid deformation.
