Hydranautics ESPA3 Low Energy RO Membrane

ESPA® (Energy Saving Polyamide) elements achieve high flux/lower pressure without compromising standards for high rejection. Since its introduction in the late 1990s, the ESPA® membrane has gained wide acceptance in the water treatment industry due to the significant operational cost savings associated with their use.

Advantages
  • Lower pressure for lower CAPEX/OPEX

Applications
  • Municipal potable and wastewater plants
  • Bottling operations
  • Light industrial

Performance
  • Permeate Flow: 14,000 gpd (53.0 m3/d)
  • Salt Rejection (nominal): 98.5 %

Application Data

Maximum Applied Pressure600 psig (4.14 MPa)
Maximum Chlorine Concentration< 0.1 PPM
Maximum Operating Temperature113 °F (45 °C)
pH Range, Continuous (Cleaning)3.0 - 10.0
Maximum Feedwater Turbidity1.0 NTU
Maximum Feedwater SDI (15 mins)5.0
Maximum Feed Flow75 GPM (17.0 m3 /h)
Minimum Ratio of Concentrate to Permeate Flow for any Element5:1
Maximum Pressure Drop for Each Element10 PSI

* The limitations shown here are for general use. For specific projects, operating at more conservative values may ensure the best performance and longest life of the membrane. See Hydranautics Technical Bulletins for more detail on operation limits, cleaning pH, and cleaning temperatures
