➡️ Benefits
• Up to 98% salt rejection for high-quality permeate water
• Extra-low pressure operation reduces energy consumption
• Compatible with all standard 4" RO housings
• Long service life and stable output in brackish water systems
• Reliable operation under variable feedwater conditions

ℹ️ Additional information
• Membrane ships dry; keep wet after first use
• Use preservation solutions during extended shutdowns to prevent biofouling
• Drain permeate produced during the first hour of initial operation
• Increase inlet pressure gradually (30–60 seconds) and ramp up flow (15–20 seconds) during startup to prevent hydraulic shock
• Flow rate may vary by ±20% from the nominal value
