Kerasep™ - Membrane Filtration
Membrane filtration is a purification process used to separate particles from soluble compounds in a liquid flow, based on their physical size, which is very often closely correlated to their molecular weight . With cross flow filtration (CFF), also called tangential flow filtration (TFF), the fluid flows tangentially to the filtration membrane and only a portion will flow across thanks to the pressure applied, instead of having all the flow frontally passing through, while particle would accumulate at the surface of the media.
It is therefore a pressure-driving purification technology, where the thinner the membrane porosity is, the more resistance you have to the permeation flow and more pressure (or power) you need to apply. The membrane filtration can be used for clarification (suspended particles or turbidity removal), concentration of one group of molecules (versus smaller ones) or soluble removal (thanks to diafiltration). At industrial scale, it can be designed in systems running in batch fed-batch or continuous mode.
Cross-flow filtration is widely used in various industries and with various types of membranes, including sugar, sweeteners, dairy, biomass fractionation and fermentation.
For more than 4 decades, we have been designing, building and commissioning optimized industrial solutions for microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO).
We offer a full range of state-of-the-art technologies for Cross Flow Filtration, also sometimes called Tangential Flow Filtration (TFF):
- Ceramic membranes, modules and units for MF and UF.
- Organic membranes, modules and units for UF, NF and RO.
- Full set of ancillary pieces of equipment, among them Cleaning in Place units, which guarantee steady and long lasting membranes performances.
Our processes development services can then design virtually any kind of challenging process, especially yours.
Membranes
Our Kerasep™ ceramic membranes offer many advantages for industrial processes:
- Superior performance in a more compact design (ratio of surface versus volume has been maximized).
- Ultra-resistant to high temperatures and extreme pH for extra long durability.
- Kerasep™ membranes are also highly resistant to back-pulse cycles.
Modules
Improve the benefits of your membranes with Applexion’s Kerasep™ modules:

Kerasep™ modules have been recognized by the industry for their quality and robustness for decades. Their optimized design ensures high cleanability and excellent performance in operations.
Thanks to our smart single-piece gasket technology, Kerasep™ modules are easy to inspect and maintain.
Systems
With a strong and recognized experience in membrane design, CFF process development, and industrial plant engineering, construction and commissioning, Applexion teams are able to provide you with complete and optimized CFF units.
Thanks to process modelling, data computerization and engineering expertise, we design CFF units combining high-performance, efficient process integration and balanced CAPEX/OPEX. With our pilot units, and by performing in-depth feasibility studies focused on your objectives, we are able to deliver industrial solutions with guaranteed process performance.
Applexion’s Jumbo Skid is an innovative unit composed of 2 times more modules for the same footprint on the ground. This outstanding design brings interesting benefits for your process line:
- Largest filtration working area.
- Optimized layout for a reduced footprint and CAPEX.
- Lower power consumption rate per filtration surface.
Jumbo Skid exits in two sizes:
- 16 modules for an 8-module footprint.
- 20 modules for a 10-module footprint.
