Membranes

Reverse osmosis (RO) technology traces its origins to the early 20th century, based on the principle of osmosis, where water moves through a semi-permeable membrane from areas of lower solute concentration to higher concentration. In the RO process, pressure is applied to reverse this natural flow, enabling water to pass through the membrane while leaving behind dissolved salts and impurities.

Significant advancements in membrane development occurred in the 1950s, leading to commercial applications in the 1970s, particularly in seawater desalination. Over time, RO technology has diversified into various sectors, including food production and pharmaceuticals. It plays a crucial role in tackling global water scarcity and ensuring access to safe drinking water, supported by ongoing improvements in efficiency.

Our membrane product line features high-performance, low-fouling reverse osmosis (RO) and nanofiltration (NF) spiral-wound membranes designed with smooth surfaces for low-pressure drop and reduced energy consumption. Our ultrafiltration (UF) modules, constructed using TIPS fibers, eliminate the need for liquid backwashing.

With expertise from our skilled polymer chemists, our advanced membrane technologies minimize cleaning frequency and enhance durability, thereby reducing operational costs.

Persalt offers standard product warranties, and our ROMA™ (Reverse Osmosis Membrane Analysis) software provides accurate system projections.

Additionally, we developed CIPROS7™, a patented software program for reverse osmosis clean-in-place calculations and procedures, ensuring efficient and economical chemical cleaning for composite polyamide membranes.

All Persalt membranes are available in standard configurations and can easily replace any membrane brand in existing and new systems.
