SB50 CA

Summary

Product identification

The TRISEP® SB50 series are Reverse Osmosis (RO) elements featuring a Cellulose Acetate (CA) / triacetate blend membrane. These membranes offer an excellent combination of solute rejection, fouling resistance, and chlorine tolerance. The SB50 is a higher flowing CA RO membrane suitable for water purification where chlorine is used to control biological organisms, making it ideal for applications facing biofouling issues due to its high chlorine tolerance and smooth surface morphology.

Membrane Characteristics

• Membrane Type: Cellulose Acetate
• Stabilized Salt Rejection: 96.0%
• Minimum Salt Rejection: 92.5%

Design Information

Elements have fiberglass outer wrap and diamond-shaped feed spacers. All models include anti-telescoping devices (ATDs) attached to the ends of the element, one brine seal, and one interconnector.

Important 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. For a more detailed start-up procedure, consult Element Start-Up Guide – System Start-Up (TSG-O-005).
• Cleaning: TRISEP® membrane elements must be cleaned periodically to ensure proper operation and to prevent membrane damage. Refer to Membrane Cleaning Guide – Cellulose Acetate Elements (TSG-C-005).
• Storage: TRISEP membrane elements must be stored appropriately to ensure proper operation and to prevent membrane damage. Refer to Element Storage Guides (TSG-O-009 & TSG-O-010).
