The AD Series, family of proprietary thin film reverse osmosis membrane elements, is characterized by an excellent sodium chloride rejection. AD series is selected when high quality permeate is demanded from seawater that is relatively high in TDS.  AD series new membrane chemistry provides excellent rejection characteristics when operated at seawater operating conditions (pressures exceeding 800 psi
(5,516 kPa) and elevated temperatures). AD series is certified to NSF/ANSI 61.
