fILTRATION CHALLENGE
The in-place self-cleaning filter was no longer satisfactory. Indeed, the scraping system used to unclog the filter basket generated release of contaminants incompatible with the expected emulsion quality, which is part of the adjuvant manufacturing process.
The customer was seeking an ergonomic solution, easy to operate and maintain.
The specifications defined the following parameters:
- Filtration of an emulsion with a cut-off of 200 µm
- With a density from 1.02 to 1.05
- With a viscosity from 600 cP to 1800 cP
- For a service flow rate of 10 m³/h
- And a clean-in-place (CIP) flow rate, by backwashing, of 45 m³/h
pEMFLOW FILTRATION SOLUTION
The proposed solution consists of a filter housing made of 316L stainless steel, combined with a 316L stainless steel basket.
The installed filter housing features the following characteristics:
- Maximum operating pressure: 10 bar
- Maximum operating temperature: 110°C
- Inlet/Outlet: DN50 PN16
- Vent: 1/2 inch BSP F
- Upstream drain: 1/2 inch BSP F
The seal, in accordance with customer requirements, is FDA certified. The filter housing complies with the requirements of the European Pressure Equipment Directive (PED), Article 4.3 (Group 2 fluid).
Expert advice
PED (Pressure Equipment Directive)
All pressure equipment placed into service in Europe must comply with the Pressure Equipment Directive 2014/68/EU. This directive requires that all pressure equipment and assemblies above specified pressure and/or volume thresholds meet the essential safety requirements covering design, manufacturing, and testing, comply with the appropriate conformity assessment procedures, and bear the CE marking and/or other required information.
