SepPure’s cutting-edge nanofiltration membranes revolutionize industrial chemical separation processes across many sectors, including chemical, pharmaceutical, petrochemical, semiconductor, performance materials, and food & beverage, amongst many others. Designed for high selectivity and efficiency, these chemical-resistant membranes enable diverse applications including solvent recovery, solute removal, product upgrading, solvent exchange, monomer removal, and many more, while significantly reducing energy consumption and operational costs. From solvent extraction in vegetable oil production to active pharmaceutical ingredient (API) purification, our membranes offer a reliable, cost-effective solution for industrial processes.
How Our OSN Technology Works:
Organic Solvent Nanofiltration (OSN) membranes represent a cutting-edge filtration technology, operating at a molecular level to precisely separate molecules based on their size and charge. These highly advanced membranes effectively retain particles and molecules above a specific size threshold while allowing smaller molecules to pass through, thereby facilitating precise molecular separation. At SepPure, we specialize in delivering advanced nanofiltration membranes tailored to diverse filtration requirements across industries, ensuring efficient separation and purification processes.
In contrast to conventional methods such as distillation, which heavily rely on burning fossil fuels to generate energy for separation, our nanofiltration approach entirely circumvents this reliance. By eliminating the necessity for heat, we have pioneered a significantly cleaner and more sustainable process. At SepPure Technologies, we are redefining the chemical separation landscape, enabling a more sustainable and energy-efficient future.
SepPure Technologies’ OSN membranes use 580x less energy than conventional chemical separation methods.

Applications of Nanofiltration Membranes
Bridging the gap between ultrafiltration (UF) and reverse osmosis (RO), nanofiltration (NF) membranes are applicable to a wide range of industrial applications. They offer a more cost-effective and environmentally friendly alternative to conventional separation processes where high energy use and solvent demand are concerns. The pore size of nanofiltration membranes can range between 0.5 - 2.0 nanometers, allowing for efficient and precise separation of chemicals at the molecular level. These attributes make OSN membranes applicable across a wide range of industries where solvent-based separations are common, including:
Edible Oil: Improve the processes of solvent extraction, deacidification, solvent fractionation, and more, substantially lowering the industry’s environmental impact while making operations more efficient.
Pharmaceutical: Enable solvent exchange, catalyst recovery, and purification of active pharmaceutical ingredients (APIs), reducing both solvent waste and energy use.
Semiconductor: Enable energy-efficient recovery of over 90% of spent solvents, allowing them to be cascaded into other processes and industries.
Specialty Chemicals: Enable non-thermal recovery of active catalysts, gentle concentration of fine chemicals, and improve crystallization processes.
And many more.
Their unique properties including pore size, selective permeability, and chemical resistance make OSN membranes a cost-effective, energy-efficient, and sustainable solution.
SepPure’s Solutions Powered by GreenMem® OSN Membrane
Powered by its cutting-edge technology of GreenMem® organic solvent nanofiltration (OSN) membrane, SepPure Technologies has designed and developed various solutions, including RE(SOLV)® and DE(SOLV)® to address the growing need for sustainable chemical separation processes across industries.
RE(SOLV)® Solution
Our heatless solvent recovery system, RE(SOLV)®, revolutionizes industrial solvent recycling. This advanced system filters solvents using a pressure-driven, heat-free method, allowing spent solvents to be recovered and either reused in the same industrial applications or resold as high-quality technical-grade solvents for other processes. Unlike traditional methods that dispose of spent solvents through incineration, our approach prioritizes recovery and reuse, enabling efficient filtration and delivering high-quality, reusable solvents.
DE(SOLV)® Solution
DE(SOLV)® is a revolutionary, energy-efficient desolvation process specifically designed for the oil industry. This pressure-driven technology removes up to 90% of solvents from oils without the need for heat, drastically reducing energy consumption and making the process safer, especially when dealing with flammable solvents.
Our solution offers a transformative approach for large-scale solvent plants, including vegetable oil refineries, waste oil processors, and solvent processors, enhancing sustainability and operational efficiency.
