AK2540TM

Summary

Product identification

The AK Series comprises Low Energy Brackish Water RO Elements, featuring A-series, thin-film membrane (TFM) technology designed for high flux and high sodium chloride rejection at low operating pressures. These elements allow for significant energy savings by achieving good rejection at operating pressures as low as 100 psi (689 kPa).

The specific model covered here is the AK2540TM.

• Membrane: A-series, thin-film membrane (TFM)
• Part Number: 1206802

Product water

Testing conditions for the following parameters: 500 ppm NaCl solution at 115 psi (793 kPa) operating pressure, 77°F (25°C), pH 7.5, and 15% recovery. Average salt rejection is measured after 24 hours of operation. Individual flow rate may vary ±20%.
