Hydranautics ESPA2 MAX Low Energy RO Membrane

 

The Hydranautics ESPA2 MAX is a high-productivity Low Energy Brackish Water RO Element engineered to deliver maximum water output while minimizing energy consumption. As part of the "ESPA" (Energy Saving Polyamide) series, this membrane is designed for applications demanding high-energy efficiency without compromising on salt rejection. By utilizing an expanded 440 ft² active surface area, the "MAX" configuration achieves a remarkable flow rate of 12,000 GPD, allowing system designers to reduce the total number of pressure vessels needed and significantly lower capital expenses (CAPEX) and floor space requirements.

This 8-inch commercial membrane operates at an optimal test pressure of 150 PSI, making it an excellent choice for treating well water, surface water, and wastewater. It utilizes advanced composite polyamide chemistry to maintain an impressive stabilized salt rejection of 99.6%. Ideal for large-scale municipal wastewater reclamation, bottling operations, and light industrial applications, the ESPA2 MAX provides a perfect balance of high permeate quality, exceptional flow capacity, and reduced operating costs.
