Summary
Product identification
The TRISEP® ACM2 series consists of high rejection brackish water reverse osmosis (RO) elements. The ACM2 membrane is described as MICRODYN-NADIR’s highest volume membrane, offering very high solute rejection and serving as a direct replacement for competitive RO products. These membranes are available in numerous strong and durable spiral-wound element designs.

ᶜ Shipping weight is dependent on packaging material and quantity shipped. ᵈ Diameters for Dimension “C” are as follows. For Female elements, “C” is the Inner Diameter. For Male elements, “C” is the Outer Diameter. ᵉ Male elements have a protruding permeate tube, indicated as “D” in the diagram. Dimension “D” is 25.4 mm (1.0 in).
Important Operating Information
- Start-up: MANN+HUMMEL Water & Fluid Solutions recommends flushing elements for 30 minutes at low pressure and discarding permeate during the flush prior to operation.
- Cleaning: TRISEP® membrane elements must be cleaned periodically to ensure proper operation and to prevent membrane damage.
- Storage: TRISEP membrane elements must be stored appropriately to ensure proper operation and to prevent membrane damage.
