💧 Hydranautics ESPA4-LD-4040 Reverse Osmosis Membrane
Product Description
The Hydranautics ESPA4-LD-4040 is a professional-grade 4-inch by 40-inch Reverse Osmosis (RO) element from the acclaimed Energy-Saving Polyamide (ESPA) series. Manufactured by Hydranautics (a Nitto Group Company), this low-energy membrane is specifically designed for brackish water and industrial applications where achieving high salt rejection at ultra-low operating pressures is crucial.
The ESPA4-LD is a standard choice for two-pass RO systems or applications that demand exceptional water quality, as it boasts a high nominal salt rejection of (minimum ). It delivers a permeate flow of while operating at a mere test pressure, leading to significant savings on energy costs.
Featuring Low Differential (LD) Technology and a 34 mil feed spacer, the element actively minimizes colloidal fouling. This patented design ensures consistently low feed pressures, extends the time between required chemical cleanings, and ultimately increases the longevity and reliability of the membrane.
