About Persalt

Persalt supplies durable and high-quality reverse osmosis & ultrafiltration membranes; and ion-exchange resins designed for water and process applications.

Engineers with more than four decades of experience in liquid separations technologies founded Persalt in 2018.

We offer high-performance and low fouling RO & NF spiral wound membranes with smooth surface features and uniform particle size (IX) ion-exchange resins with high capacities for a diversity of separation processes. Persalt supplies high flux capillary ultrafiltration modules with a direct retrofit product line to provide customers who use UF products made by other manufacturers. We also offer our UF modules with TIPS fibers and no liquid backwash.

Through the WeROcycle ™ concept, we are the unique membrane supplier to manage its membranes disposal through element recycling.

Persalt follows the extended producer responsibility practices essential for protecting our environment, reducing plastic waste disposal in landfills.

Traditional suppliers have complex administrative, manufacturing, commercial, and operational structures carrying tremendous overhead costs to their products.

On the other hand, Persalt has an appropriate company structure and deep technology knowledge. We use outsourcing production, high-quality materials, and the most rigorous RO membranes and IX resins specifications and manufacturing standards.

For this reason, we provide the best cost-benefit products in the marketplace with the same warranties & performance of the traditional suppliers.

We have the flexibility of customizing RO/NF/UF membranes and IX resins to meet your specific process requirements.

Persalt also offers technical and sales support with a timely response to customer requests worldwide.
