Introduction
The Reverse Osmosis Membrane Model BW30-365 is a cutting-edge solution designed to meet the rigorous demands of industrial water treatment, particularly in applications requiring high-purity water. Manufactured by leading companies like DuPont/Dow Filmtec and compatible with global brands such as Hydranautics, Toray, and GE, the BW30-365 is a premium reverse osmosis (RO) membrane renowned for its high efficiency, durability, and versatility. Engineered for both brackish water and seawater desalination, this membrane combines advanced materials and innovative design to deliver superior performance in removing dissolved salts, organic contaminants, and microorganisms. As industries increasingly prioritize water sustainability and compliance with strict quality standards, the BW30-365 stands out as a reliable choice for applications ranging from food and beverage production to power generation and wastewater reclamation. Its ability to operate under low pressure while maintaining high rejection rates makes it a cost-effective solution for optimizing water treatment processes. Product Parameters The BW30-365 is precision-engineered to meet the highest industry standards. Key parameters include: Parameter Specification Model BW30-365 Membrane Type Polyamide Composite (TFM) Effective Area 365 ft² (33.9 m²) Average Flow Rate 9,600 gallons/day (36.3 m³/day) NaCl Rejection 99.5% (at 2,000 ppm NaCl, 225 psi, 25°C, 15% recovery) Maximum Operating Pressure 600 psig (4,137 kPa) Maximum Temperature 122°F (50°C) pH Range 4.0–11.0 (continuous operation) Dimensions 8-inch diameter × 40-inch length (203 mm × 1,016 mm) Seal Material EPDM or Buna-N Recommended Changeout Pressure 2.5 bar (36 psid) at 20°C Product Specifications The BW30-365 is available in configurations optimized for diverse industrial needs: Membrane Material: Polyamide Composite: Offers superior chemical resistance and long-term stability. FDA-Compliant: Suitable for food, pharmaceutical, and beverage applications. Filtration Rating: Absolute 99.5% NaCl Rejection: Ensures ultra-pure water even in high-salinity environments. Design Features: Spiral-Wound Construction: Maximizes surface area while minimizing footprint. Coreless Design: Reduces pressure drop and enhances dirt-holding capacity. Fiberglass Reinforced Polypropylene (FRP) Shell: Provides structural integrity and corrosion resistance. Compatibility: Brackish Water: Ideal for TDS ≤ 10,000 ppm. Seawater: Requires pretreatment for TDS ≥ 35,000 ppm. Key Advantages High Efficiency & Low Energy Consumption: Operates at 225 psi (1,550 kPa), significantly reducing energy costs compared to traditional systems. Achieves 99.5% salt rejection with minimal water loss. Extended Service Life: Advanced polyamide composite material resists fouling and chemical degradation. Low-pressure operation minimizes mechanical stress on the membrane. Anti-fouling: Optimized surface chemistry reduces colloidal and organic fouling, extending cleaning intervals. Versatility: Suitable for a wide range of applications, including desalination, wastewater reuse, and ultra-pure water production. Easy Maintenance: Modular design allows quick replacement and compatibility with standard RO systems. Working Principle The BW30-365 operates on the principle of reverse osmosis, where water is forced through a semipermeable membrane under pressure, separating contaminants from pure water: Cross-Flow Filtration: Water flows tangentially across the membrane surface, minimizing fouling and maximizing efficiency. Selective Permeation: The polyamide membrane rejects dissolved salts, organic matter, and microorganisms while allowing water molecules to pass through. Concentration Polarization Control: Proprietary spacer design ensures uniform flow distribution, reducing salt buildup on the membrane surface. Energy Recovery: Optional energy recovery devices further enhance efficiency in high-pressure applications. Application in the Food Industry The BW30-365 plays a critical role in ensuring safe and high-quality food production: Beverage Production: Desalination and Softening: Removes excess minerals from water used in brewing, soft drinks, and bottled water. Microbial Control: Eliminates bacteria, viruses, and endotoxins to meet FDA and HACCP standards. Dairy Processing: Whey Concentration: Converts whey into valuable byproducts like lactose and protein isolates. Cleaning Water: Provides ultra-pure water for equipment sanitization. Brewing: Water Quality Adjustment: Removes sulfates and nitrates to prevent off-flavors in wine and spirits. Fruit and Vegetable Processing: Water Saving and Recycling: Treats wastewater for reuse in washing and blanching processes. Case Study: A major beverage manufacturer reduced water usage by 40% and membrane replacement costs by 30% using BW30-365 in their RO system.
