ESPA2-LD Hydranautics Nitto 10,000 GPD at 150 PSI 8 x 40 inch 99.6% Rejection Membranes

Hydranautics ESPA2-LD Low Energy RO Membrane

The Hydranautics ESPA2-LD is a high-productivity, energy-saving polyamide reverse osmosis membrane designed for demanding brackish water applications. Featuring Hydranautics' proprietary Low Differential (LD) Technology, this 8-inch commercial membrane is engineered with enhanced chemistry to provide exceptional chemical resistance and a 34-mil feed spacer that minimizes trapping of small colloidal particles. The specialized biostatic properties significantly retard bacterial growth, extending the interval between cleanings and ensuring consistent, high-quality permeate flow in industrial and municipal wastewater reclamation systems.

Operating at a low test pressure of 150 PSI, the ESPA2-LD produces a reliable 10,000 Gallons Per Day (GPD) while maintaining an impressive stabilized salt rejection of 99.6%. By combining low-pressure operation with high fouling resistance, this membrane reduces overall power consumption and limits the carbon footprint of the system. Furthermore, it incorporates a patented vented seal carrier that eliminates pressure-shock damage during system start-up, ensuring long-lasting durability in challenging feedwater environments.
