SUEZ AG4040TM ; 4"x40" 2300 GPD Replacement Reverse Osmosis Membrane - Tap/Brackish Water (Veolia)

Veolia A-Series – AG4040TM High Rejection Brackish Water RO Membrane

The A-Series is a family of proprietary thin-film reverse osmosis (RO) membrane elements, known for:

• High water flux

• Excellent sodium chloride (NaCl) rejection

• Low operating pressure requirements (as low as 200 psig / 1,379 kPa)

• Energy-efficient performance – moderate energy savings

• Industry-standard reliability for brackish water applications

The AG4040TM model is specifically engineered for high rejection performance and includes:

• Tape outer wrap for durability

• 28 mil feed spacer for improved flow dynamics

• Male end connections for easy integration
