ESPA B MAX

ESPA B MAX

Product catalog summary
Product Overview: The ESPAB MAX is a spiral wound membrane element designed by Hydranautics for water treatment applications. It features a composite polyamide membrane with an active area of 440 ft2 (40.8 m2).
Performance Specifications: The membrane offers a permeate flow of 9,000 gallons per day (34.1 m3/d) and a salt rejection rate of 99.3% (minimum 99.0%). Typical boron rejection at pH 10 is 96.0%.
Application Data: The maximum applied pressure is 600 psig (4.16 MPa), with a chlorine concentration limit of less than 0.1 PPM. The membrane operates effectively at temperatures up to 113°F (45°C) and within a pH range of 2-11 for continuous use, extending to 1-12.5 for cleaning. Feedwater turbidity should not exceed 1.0 NTU, and the maximum feed flow is 75 GPM (17.0 m3/h). The concentrate to permeate flow ratio must be at least 5:1, and the maximum pressure drop per element is 10 psi.
Test Conditions: Performance data is based on initial testing after 30 minutes of operation using a 1500 PPM NaCl solution at 150 psi (1.05 MPa) and 77°F (25°C), with a permeate recovery of 15% and a pH range of 6.5-7.0. Boron testing involves a 10 mg/L boron solution adjusted to pH 10.
Physical Dimensions: The element measures 40.0 inches (1016 mm) in length, 7.89 inches (200 mm) in diameter, and 1.125 inches (28.6 mm) in core diameter, weighing 36 lbs (16.4 kg).
Packaging and Variability: Each membrane element is supplied with a brine seal, interconnector, and o-rings, packaged in a sealed polyethylene bag with less than 1.0% sodium meta-bisulfite solution, and enclosed in a cardboard box. Variability in permeate flow, membrane active area, and element weight is noted.

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. Test Conditions The stated performance is initial (data taken after 30 minutes of operation), based on the following conditions: 1500 PPM NaCl solution 150 psi (1.05 MPa) Applied Pressure 77 F (25 C) Operating Temperature 15% Permeate Recovery 6.5 - 7.0 pH Range (For boron testing, 10 mg/L boron is added and pH adjusted to 10 with NaOH) PERMEATE CONCENTRATE A, inches (mm) 40.0 (1016) Notice: Permeate flow for individual elements may vary + or - 15 percent. Membrane active area may vary +/-4%. Element weight may vary. All membrane elements are supplied with a brine seal, interconnector, and o-rings. Elements are enclosed in a sealed polyethylene bag containing less than 1.0% sodium meta-bisulfite solution, and then packaged in a cardboard box. † When tested at standard test conditions with 5.0ppm Boron in feed solution.
