Description
Cylindrical Membralox®
Ceramic Membranes
Type EC0760 and EC1935
Cylindrical Membralox ceramic elements feature the same exceptional performance, mechanical and chemical resistance and service life as the well-recognized Membralox product range.
These membrane geometries are intended to be compatible with a wide range of filter suppliers housing designs.
Membralox membranes are the key components of crossflow systems used in numerous food and beverage applications, such as clarification / concentration / purification of fermentation broths,dextrose syrups, fruits juices, dairy products, etc.
Description
These Membralox ceramic elements are asymmetric multi-channel membranes composed of a porous alumina support supporting filtering layers casted on the inner surface of the lumens.
Pall Membralox membranes are made from high purity ceramic oxides in multiple geometries.
All along the manufacturing, a stringent quality control process verifies consistency of membrane characteristics versus precise acceptation criteria to deliver reproducible membrane performances, batch after batch, years after years.
Prior to release, Membralox membranes are 100% bubble point tested to confirm filtration layer and end sealing integrity.
| Features | Benefits |
