Pall's Membralox ceramic membrane elements are ideal for applications that involve extreme processes, such as high solids bulk processes, the use of high temperatures or pressures, or aggressive solvents, and where significant long-term durability is required.
Available ratings start at very low molecular weight ultrafiltration used for duties such as unwanted protein removal from antibiotic solutions, through to open (up to 5 µm) microfiltration membranes that can be used to process difficult materials such as microspheres, or clarify solvent-based plant extracts in transgenic processes.
Membralox membrane elements are available in 3 different channel diameters to allow optimization for solids loading. Some configurations are available with unique longitudinal permeability gradients, that facilitates the control of permeate rate along the length of the module.
Membrane elements are available in sizes ranging from small laboratory devices through individual modules of over 20 square meters surface area, ensuring the ability to evaluate and scale up processes to any size.
Membralox ceramic membranes comprise a highly controlled surface membrane layer that is formed on the inner (feed-side) surface of a more open support layer. Three different types of materials are available, ultrapure, µalumina, zirconia and titania. All of these materials are FDA-listed for suitability in pharmaceutical processes. Ceramic membranes exhibit near zero non-specific adsorption of biological materials.
Membralox ceramic elements featuring an asymmetric membrane structure combine a unique design and manufacturing process resulting in a product ideally suited for applications involving chemicals, including solvents, extremes of pH, high temperatures and pressure processing of and fermentation broths.
The compact multi-channel geometry and high permeability are optimized for bulk processing applications. Multiple modules each comprising a number of membrane elements can be easily assembled on manifolds to handle any scale of operation.

Membralox membrane elements are assembled in housings containing modules with up to 60 elements per module. This versatility simplifies system designs, allowing optimal sizing of membrane area for each application.
he Membralox GP range of ceramic membrane elements have a calibrated longitudinal permeability gradient, that maintains a constant and uniform flux along all parts of the element. This optimizes the microfiltration of complex, transmission sensitive feed streams.
The Membralox SD module features a fully sanitary design for stringent pharmaceutical processes. All wetted components are swept by cleaning solutions ensuring compliance with requirements of cleaning validation.
Module hardware and gaskets are available in materials that meet the demands of all cleaning regimes.
The Membralox HCB module range takes advantage of the unique hexagonal shape of the Membralox ceramic membrane elements to obtain a high membrane packing density up to 240 m2/m3 (2583 ft2/ft3), thus significantly reducing filtration system costs.
Features of the HCB module – increased surface area, reduced permeate hold-up volume, PTFE gaskets for a wider chemical compatibility – provide economical solutions in bulk fermentation broth clarification and pharmaceutical effluent treatment.
Potential applications can be conveniently evaluated using this laboratory scale module with integrated ceramic membrane element. Feasibility testing allows the appropriate membrane pore size to be selected for pilot scale studies. The module has a low permeate hold–up volume of 7 mL.
Pilot-scale evaluation of Membralox technology with full scale modules can be performed on pilot plant systems. Several options are available on request.
