Pervaporation membrane for solvent dehydration
Efficiently separate and dehydrate solvents at molecular levels, ensuring purity in every phase of production for high-stakes applications.

Dehydrates and Purifies Solvents Efficiently
The Pervaporation Membrane System from BORSIG Membrane Technology excels in solvent dehydration, offering a sophisticated solution for the pharmaceutical, fine chemical, and biofuel industries. This system employs a high-water affinity membrane that effectively adsorbs and separates water from organic solvents without relying on vapor/liquid equilibrium, making it ideal for exacting dehydration tasks.
Suitable for both continuous and batch processing, the system efficiently handles a variety of applications, such as ethanol and isopropanol dehydration, supporting the recovery of high-purity Active Pharmaceutical Ingredients (APIs) and bioethanol. This membrane system integrates seamlessly with existing production lines, reducing energy consumption compared to traditional distillation methods by eliminating the need for entrainer chemicals or pressure swing operations.
Designed to fit within your existing infrastructure, it features compact modular units making installation possible within existing production buildings, thus minimizing spatial requirements. Constructed from durable, corrosion-resistant materials, it provides lasting service, while its compliance with industry standards ensures a smooth operation within your regulated environments. Additionally, BORSIG offers comprehensive engineering support, allowing for customization to meet your specific process demands, bolstered by reliable service and maintenance options.
