NALA Membranes

951 Aviation Parkway, Suite 900
27560 Morrisville, NC USA

Business Description: NALA Membranes has developed chlorine stable reverse osmosis and nanofiltration membranes from patented polymers. Commercial membrane products are being manufactured and sold for installations in industrial wastewater applications. Additional commercial application in sulfate removal for offshore oil drilling is being pursued. Multiple chlorine stable membrane products spanning a range of flux and rejection are available in sheet and spiral wound element formats standard to the industry. Sales are currently both domestic and international.

Offer: Unique sulfonated polysulfone reverse osmosis and nanofiltration membranes. Treating high strength wastewaters requires the ability to clean membranes rapidly without damage and NALA's membranes can be cleaned aggressively with high concentrations of chlorine bleach to remove organic foulants and biofouling without damaging the membranes. Smooth membrane surfaces minimize fouling and scaling and the materials can be operated in a much wider range than standard polyamide membranes. Reducing operating costs, by reducing cleaning frequency and duration and membrane replacement. Potentially reducing capital costs through reduced pretreatment, CIP equipment, and redundancy.

Looking For: High demand is driving the need for increased production capacity. Manufacturing at scale will drive down production costs to at or below standard polyamide membranes while increasing value for the customer even with premium priced membranes. Looking for water, cleantech, or industrial focused investors to support our growth and transition to profitability.
