Application Areas
How ceramic membrane filtration works in the chemical industry
Physical principle of filtration
Filtration in the chemical industry is based on a purely physical separation principle. Under moderate pressure, the process medium flows tangentially along the membrane surface, known as crossflow filtration. This flow configuration continuously removes solids such as catalyst residues, pigments or colloids from the membrane surface. As a result, permeate flux remains stable, fouling is significantly reduced, and filtration performance stays consistent and efficient over long operating periods.
Structure of ceramic membranes
The ceramic membranes used are manufactured from materials such as aluminium oxide, zirconium oxide or silicon carbide. Their multilayer structure combines high mechanical strength with a fine-pored separation layer, enabling precise separation of particles and molecules. Depending on the membrane type, separation performance ranges from microfiltration to ultrafiltration and nanofiltration. This allows even fine organic intermediates or acids to be selectively separated.
Resistance to aggressive media
Exceptional resistance to aggressive process media is a key requirement in the chemical industry. Whether exposed to strong acids, concentrated alkalis or organic solvents, ceramic membranes maintain their performance even under permanently extreme operating conditions.
Cleaning and long service life
Our membrane modules are fully CIP-capable and can be cleaned chemically or thermally, including with highly aggressive cleaning agents. This ensures consistently high separation performance over many years. Combined with their robust design, this results in an exceptionally long service life—even in continuous, high-load industrial operation.

FAQ - Frequently Asked Questions on Filtration in the Chemical Industry
Our ceramic membranes offer long-term resistance to concentrated acids, strong alkalis and organic solvents. This makes them ideally suited for processes operating under extreme chemical conditions.
Yes. Thanks to their modular design, the systems can be easily integrated into existing reactors, filtration stages or process loops.
The membrane modules are fully CIP-capable and can be cleaned using aggressive media such as caustic soda, acids or hot water. This ensures stable flux rates even when abrasive particles or organic residues are present.
Yes. Ceramic membranes enable the recovery of catalysts, intermediate products or organic acids directly from the process stream. This reduces product losses and improves overall cost efficiency.
Tangential flow actively removes deposits from the membrane surface. This is particularly important when processing pigments, colloids or highly viscous media, as it reduces fouling and ensures stable, continuous production.
Yes. The membrane systems are designed in accordance with applicable standards and regulations, such as the Pressure Equipment Directive (PED) 2014/68/EU, ASME or AD 2000.
Fouling refers to the accumulation of particles, oils, colloids or other substances on the membrane surface. These deposits clog the membrane pores, reduce permeate flux and increase energy consumption. In severe cases, fouling can lead to frequent cleaning cycles or even system failure.
