OSMO Membrane Systems GmbH
About
OSMO Membrane Systems GmbH, founded in 1980 and part of the GAW Gruppe, is a specialized manufacturer of industrial membrane filtration and separation systems based in Germany. The company delivers the full spectrum of membrane technologies—microfiltration, ultrafiltration, nanofiltration, reverse osmosis, ion exchange, membrane degassing, and dialysis—serving six industry sectors: pulp and paper, chemicals and polymers, power and water, surface and coating, metals and recycling, and biotech, cosmetics, and sugar. OSMO's structured approach moves from in-house laboratory membrane screening through industrial piloting with the MemCell mobile pilot unit to full-scale plant delivery and ongoing optimization. Their engineering team develops custom separation solutions for complex industrial streams, with particular depth in pulp and paper black liquor concentration and fractionation, chemical product recovery from wastewater, and metals resource recovery from process solutions. The GAW Group affiliation provides access to complementary process engineering capabilities for integrated plant projects. OSMO maintains its own laboratory for process development and membrane selection, enabling the company to identify optimal membrane types and operating conditions before clients commit to full-scale investment.
Key Products
Membrane filtration systems using 0.1-10 micron pore sizes to separate suspended solids, bacteria, and large colloids from process liquids and wastewater.
Membrane systems with 0.01-0.1 micron pore sizes that remove proteins, colloids, and high-molecular-weight organics for product recovery and water recycling.
Pressure-driven membrane processes that selectively remove divalent ions, organics, and color compounds while allowing monovalent ions to pass, used for softening and partial desalination.
High-pressure membrane desalination systems that remove virtually all dissolved salts and organics, producing high-purity permeate for water reuse or process applications.
Ion exchange resin-based systems for selective removal of dissolved ions from process water and wastewater, enabling demineralization and selective ion recovery.
Membrane contactor systems that remove dissolved gases such as CO2 and O2 from water without chemical addition, protecting downstream processes.
Diffusion-based membrane separation systems that selectively remove low-molecular-weight solutes from process streams.
Mobile pilot-scale membrane testing unit for on-site process validation and optimization before full-scale plant investment.
Laboratory testing services to identify optimal membrane types and process conditions for specific separation challenges.
Ongoing technical support, performance monitoring, and system optimization services for installed membrane plants.
