UPL21-4021 Vontron RO Membrane – Ultra-Low Pressure Reverse Osmosis Element The UPL21-4021 Vontron RO Membrane is a high-performance reverse osmosis membrane designed for ultra-low pressure operation. This membrane is ideal for applications requiring efficient desalination of surface water, underground water, tap water, and municipal water sources with a salt concentration lower than 2000 ppm. Key Features Ultra-Low Operating Pressure: Operates at approximately two-thirds the pressure of regular low-pressure composite membranes, reducing energy consumption and operational costs. High Salt Rejection: Achieves a stable salt rejection rate of up to 99%, ensuring high-quality purified water. Large Active Membrane Area: With an active membrane area of 36 ft² (3.3 m²), it provides a high permeate flow rate. Durable Construction: Built with high-quality materials to withstand the demands of continuous operation in various water treatment applications. Technical Specifications Model: UPL21-4021 Active Membrane Area: 36 ft² (3.3 m²) Permeate Flow: 950 GPD (3.6 m³/day) Stable Salt Rejection: 99% Minimum Salt Rejection: 98.5% Test Conditions: 150 psi (1.03 MPa), 1500 mg/L NaCl, 25°C (77°F), pH 7.5, 8% recovery rate Applications The UPL21-4021 membrane is suitable for various applications, including: Pure Water Production: Ideal for producing high-purity water for industrial processes. Boiler Water Replenishment: Provides high-quality water for boiler systems, reducing scaling and maintenance. Food and Beverage Processing: Ensures the production of clean water for food and beverage manufacturing. Pharmaceutical Production: Meets the stringent water quality requirements for pharmaceutical manufacturing processes. Installation and Maintenance Tips Pre-Treatment: Ensure proper pre-treatment of feedwater to protect the membrane from fouling and scaling.
