AE-90

Summary

Product identification

The AE Series consists of high rejection, low energy seawater reverse osmosis (RO) elements. These proprietary thin-film elements are characterized by excellent sodium chloride (NaCl) rejection and are selected for applications requiring high quality permeate from seawater with relatively high Total Dissolved Solids (TDS). The AE series membrane chemistry provides excellent rejection characteristics when operated at seawater conditions (pressures exceeding 800 psi (5,516 kPa)).
