Wide spectrum, many applications

ProMinent is an expert in membrane filtration and supplies a wide range of high-quality system technology. Combined with the extensive ProMinent® product range, made-to-measure solutions can be developed. ProMinent membrane technology covers ultrafiltration, nanofiltration and reverse osmosis, including pre- and post-treatment precisely matched to the membrane system.

A convincing physical process

Membrane filtration is a physical process to separate substances with the help of membranes. There are four types of process, depending on the size of the particles / molecules to be removed: microfiltration, ultrafiltration, nanofiltration and reverse osmosis.

Let’s get started

Out of all the available methods, ProMinent specialises in systems for ultrafiltration, nanofiltration and reverse osmosis. ProMinent experts will put together the optimum system for you. Combined with the ProMinent product range, you can source complete water treatment solutions from one supplier.

Nanofiltration is an alternative to reverse osmosis. It is based on the same principle as reverse osmosis but the separating limit is somewhat lower, which reduces costs.

Reverse Osmosis Systems

A system that can remove over 99 % of all salts from an aqueous solution has the right to be called high-performance. And that’s exactly what ProMinent reverse osmosis systems do.


Dulcoclean® UF systems get things in order, removing turbidity, particles and microbiological impurities.
