AD-90

Summary

Product identification

The AD Series consists of high rejection seawater reverse osmosis (RO) elements. These proprietary thin film reverse osmosis (TFM) elements are characterized by excellent sodium chloride (NaCl) rejection. They are selected when high quality permeate is demanded from seawater that is relatively high in Total Dissolved Solids (TDS). AD Series membrane chemistry provides excellent rejection characteristics when operated at seawater operating conditions (pressures exceeding 800 psi (5,516 kPa) and elevated temperatures).
