Ceramic Membranes with Longitudinal Gradient Permeability
Pall Corporation is a global leader in filtration technologies with over 60 years of ceramic expertise and specialists in crossflow filtration systems.
Membralox GP-IC ceramic membranes are asymmetric multi-channel membranes composed of a porous alumina support and a filtering layer (alumina or zirconia). In conventional ceramic process conditions, the natural pressure drop during extended runs creates a non-uniform transmembrane pressure (TMP) from the inlet to the outlet of the flow channel. To correct this TMP decrease, Membralox GP-IC membranes have a longitudinal Gradient Permeability (GP) built into the support structure without modification of the filtration layer. Gradient Permeability is designed for optimum transfer of macromolecules across the ceramic membrane. Hence this design ensures a stable microfiltration regime all along the membrane while providing a cost-effective separation due to its unique design.
The revolutionary design of Intermingled Channels (IC) provides a higher surface area per membrane than an equivalent membrane with round channels and is offered as a complete systems package. In addition, the increased capacity of the IC-design filtration modules, up to 45% more than standard module configurations, enables a higher surface area with optimized system loop design. This results in more compact systems with a smaller footprint and reduced hardware costs.
The smaller hold-up volume of the system loops also results in a significant reduction of the related water and chemical cleaning costs. These membranes are hydrodynamically optimized for unidirectional flow and are especially used in applications with fluids that are difficult to handle as well as premium ingredients with stringent quality and microbial testing requirements*. The exceptional structure of Membralox filtering membranes has enabled the development of the widest range of micro and ultrafiltration applications.
*Microbial removal criteria and testing must be validated by the customer.

Membralox HCB Highly Compact Modules
A reliable design for high value and complex industrial food applications
Membralox membranes are loaded into Stainless Steel housings (SS 316L) and sealed with gaskets to create High Capacity with Flange (HCB) or High Capacity Sanitary (HCS) modules. The module range takes advantage of the unique hexagonal shape of the membranes to obtain a high membrane packing density up to 285 m2/m3, thus significantly reducing filtration system CAPEX. These modules provide economical solutions in fluid clarification, effluent reduction, and other stream purification applications especially in fluids that are difficult to handle.
HCS modules: hexagonal ceramic membranes are sealed to housing with global Polytetrafluoroethylene (PTFE) gaskets; other housing seals are made of polymer.
HCB modules: hexagonal ceramic membranes are sealed into housing with global PTFE gaskets; other housing seals are made of PTFE.
Sanitary Design (SD) housing can be certified 3-A depending on the customer’s needs. Multiple modules can be easily assembled on manifolds to create filtration loops of required membrane area. Multiple membrane loops can be connected in serial or in parallel to handle any scale of operation.
