DuPont™ FILMTEC™ BW30-4040 RO Membrane Upgrade your reverse osmosis system with the DuPont™ FILMTEC™ BW30-4040 (often referred to as “BW 8040-400”), a high-performance spiral-wound RO element designed for medium to large commercial and industrial applications. Engineered for exceptional salt rejection, durability, and consistent throughput, this membrane delivers reliable water quality even under challenging conditions. Technical Specifications Model: BW30-4040 (BW 8040-400) Membrane Type: Thin-film polyamide spiral-wound Rated Flow: 4,000 GPD (15,140 L/day) @ 225 psi, 77 °F, 1,000 ppm feed Minimum Salt Rejection: 99.5% @ 225 psi, 77 °F, 1,000 ppm feed Operating Temperature Range: 35 – 113 °F (2 – 45 °C) Maximum Operating Pressure: 600 psi (4.1 MPa) pH Range, Continuous Operation: 2 – 11 pH Range, Cleaning: 1 – 13 TDS Tolerance: Up to 5,000 ppm (higher TDS may require elevated feed pressure) Maximum Feed Flow: 15 gpm (56.8 L/min) Maximum Feed SDI: ≤ 5 (pre-filtered) Installation & Maintenance Tips Pre-Filtration: Use a 5 µm sediment filter upstream to protect against particulate fouling. Chlorine Removal: Install a carbon block filter ahead of the membrane to eliminate free chlorine and protect the polyamide layer. Optimal Feed Pressure ⚙️: Maintain feed pressure between 200–250 psi for best performance. Avoid pressure spikes. Regular Cleaning Cycle 🧹: Conduct a light cleaning (pH < 11) every 3–6 months, depending on feedwater quality. Employ appropriate low-fouling cleaning solutions. Performance Monitoring 📊: Track permeate flow and conductivity regularly. Replace the membrane if flow drops by 15% or rejection falls below 98%. Key Features High Salt Rejection 🚰 Removes up to 99.5% of dissolved solids (TDS), including heavy metals, lead, and nitrates—ensuring ultra-pure product water. Robust Flow Capacity 💧 Rated at approximately 4,000 gallons per day (GPD) under standard test conditions (77 °F, 225 psi, 1,000 ppm feed water), making it ideal for light-industrial, large office, or small plant installations. Heavy-Duty Construction 🛡 Polyamide thin-film composite design resists fouling and chlorine exposure (with proper upstream carbon pre-treatment), extending operational life. Wide pH Tolerance 🌡 Operates effectively across a pH range of 2–11 (continuous) and 1–13 during chemical cleaning, permitting flexible use in varying feedwater chemistries. Standard 8″ × 40″ Element Size 📏 Fits most industrial RO housings. Its large active area and spiral-wound configuration ensure efficient rejection and high flux.
