The A-Series family of proprietary thin-film reverse osmosis membrane are characterized by high flux and high sodium chloride rejection. AG HR LF Brackish Water Elements are selected for the treatment of impaired water when high rejection is desired. The AG HR LF membrane features a more neutral charge and therefore reduces interactions with potential foulants present in surface water or tertiary effluent.
