Flathead Forge Backs NALA Membranes' Chlorine-Stable RO Tech

The industrial water treatment market spans power generation, food and beverage, pharmaceuticals, and manufacturing. All rely on reverse osmosis for water reuse and discharge compliance. Reducing operating costs by simplifying biofouling control could make water reuse more economical, especially in regions with water scarcity or tightening regulations. NALA's membranes could lower the total cost of water treatment by removing the need for dechlorination equipment and chemicals, and by extending membrane life through reduced cleaning cycles.

Several companies have tried to develop chlorine-stable membranes. Most have struggled with performance trade-offs. NALA's sulfonated polysulfone material maintains salt rejection and flux rates comparable to polyamide, the company said. The membranes are currently in field trials at several industrial sites.

Flathead Forge is a venture fund focused on industrial technologies. Its investment in NALA signals confidence in the membrane's commercial potential. NALA plans to use the capital to expand pilot programs and engage with industrial customers, the company said.
