Engineers with extensive experience in liquid separations technologies gained since the 1980s came together to establish Persalt. They embraced the challenge of providing the industry with high-quality products that deliver low operational costs and are more affordable than those offered by traditional leading suppliers.

At Persalt, we specialize in advanced industrial and municipal water treatment solutions, prioritizing sustainability, and innovation.

We provide cutting-edge reverse osmosis membranes and ion exchange resins for effective water treatment, reuse, and processing. Our state-of-the-art products maximize performance in desalination and demineralization systems.

We take pride in our expanding presence in South America, where we have rapidly increased our market share and effectively displaced competitors' products among key users of membranes and ion exchange resins.

This success is due to two key factors: our optimized operational structure, which enables us to offer outstanding products at competitive prices, and our specialized engineers' dedication to developing innovative solutions for complex water treatment challenges.

All our products are NSF-certified and made from the highest quality materials.

We provide membranes for low fouling (LF) and low-pressure drop (LPD) characteristics, ensuring reduced operational costs and longer lifespans. Our ultrafiltration membranes are crafted from robust fibers, making them ideal for water treatment and reuse applications.

Furthermore, our uniform particle-size resin line features high-capacity ion exchange and high-surface-area adsorption resins, minimizing operational costs.

We manufacture our products in facilities across Europe, the USA, and Asia, adhering to stringent specifications while strategically maintaining stock in South America for quick and efficient customer service.

In 2025, Persalt acquired LAXWATER, the largest distributor of water treatment products in Brazil. This acquisition is part of Persalt’s strategy to expand its presence in the South American continent, strengthening its footprint through the opening of a new branch in Brazil.

Our commitment to customer satisfaction is paramount.

We provide superior technical support to all users of our products.

Our unique WeROcycle™ concept exemplifies our dedication to sustainability.

As the only membrane supplier actively managing membrane disposal through effective element recycling, we emphasize our commitment to environmental responsibility.
