Crossflow Filtration of Process
Fluids and Effluents
Pall Membralox ceramic membranes are asymmetric multi-channel membranes composed of a porous alumina support and a filtering layer (alumina, zirconia, titania).
High compactness of the multichannel membrane combined with high permeability allows the treatement of large volumes with high throughput.
The Membralox GP ceramic membranes range with longitudinal permeability gradient, ensure an homogeneous and calibrated flux along the flow channel, thus optimum utilization of membrane surface within a stable microfiltration regime.
Features
- High flux
- Wide chemical and pH (0-14) compatibility
- Excellent thermal stability
- Long term and reliable performance
- Sanitizable and sterilizable
- Ability to withstand high frequency backpulsing cycles
- 100% bubble point integrity tested during manufacturing
- Suited for high fouling fluids, viscous products, high concentration factors, fine filtration, diafiltration, automatic and easy cleaning in place (CIP)
- Meets the requirements for food usage1
Pall Membralox Membranes Quality
- Unique ceramic support of the 12 μm pore size allows the highest flux.
- Alumina end-sealing provides superior resistance to corrosion and cleaning cycles.
- High homogeneity and quality of the filtration layers for optimum filtration performances and selectivity.
- Exceptional mechanical resistance for long service life
Widest Separation Range
The exceptional structure of Membralox filtering elements has enabled the development of the widest range of micro and ultrafiltration ceramic membranes. A complete range of modules helps for scale-up from laboratory separations to full size industrial needs.Cost Effective Separations
The superior characteristics of Pall Membralox ceramic membranes provide economical solutions for high added value macro-molecule concentration, effluent recycling or reduction and difficult fluid clarification. Membralox filtration modules are the key element in process reliability.1The membranes based on high purity alumia are certified for use in contact with food fluids by Commission Directive 2005/31/EC. All membrane components are made from materials that our suppliers state meet the requirements for food contact use: Alumina and titania are GRAS. Zirconia layers on alumina support are listed in 21 CFR Sect.177.2910.
