High-Rejection Standard (High Purity)
-
The “7” series stands for: Standard Brackish Water High-Purity.
-
Primary Difference: This is a “tighter” membrane. It requires much higher pressure (usually 225 PSI) to operate, but it produces much cleaner water with a higher salt rejection rate.
-
Best For: Systems where water quality (Low TDS) is more important than electricity savings.
-
Risk of Switching: If you replace this with a “G” series (Low Pressure), the water will move too fast, and your salt rejection will drop, resulting in lower-quality water.
-
legacy Toray membranes are kept in stock specifically for older industrial systems that require exact matching of original flow specifications. While modern “D-Series” membranes are more efficient, these “Obsolete” models are often necessary for systems with fixed-speed pumps or specific pressure-drop requirements that cannot easily be re-calibrated.
Uses & Applications:
-
Legacy System Repairs: Direct replacement for systems built between 2010–2020.
-
Specific Pump Matching: For systems where modern high-flux membranes might cause pump cavitation.
Benefits:
-
Proven Compatibility: Eliminates the need for system re-engineering.
-
28-mil Feed Spacer: Features the original wider feed spacer for better handling of high-turbidity water.
