Introduction
The Reverse Osmosis Membrane Model BW30 – 365 is a high – performance water treatment component. It utilizes advanced reverse osmosis technology to actively separate dissolved salts, heavy metals, bacteria, viruses, and other minute contaminants from water. This membrane is engineered to meet the demanding water purification requirements across multiple industries and applications, delivering high – quality filtered water with remarkable efficiency.
Features
- High Salt Rejection Rate: Effectively rejects a high percentage of salts, ensuring the production of low – salinity water.
- Large Filtration Area: The 365 square feet of filtration area enables high – volume water treatment, making it suitable for both small – scale and large – scale operations.
- Durable Construction: Built with robust materials, it can withstand harsh operating conditions, providing long – term reliability.
- Energy – Efficient Design: Optimized to consume less energy while maintaining excellent water treatment performance, helping to reduce operational costs.
Technical Data
- Membrane Area: 365 square feet (34 square meters)
- Nominal Salt Rejection Rate: 99.5%
- Maximum Operating Pressure: 600 psi (41 bar)
- Permeate Flow Rate: 8500 – 10500 gallons per day (32 – 40 cubic meters per day)
- Membrane Type: Thin – Film Composite (TFC)
Suggested Operating Conditions
- Temperature: 5 – 45 °C
- pH Range: 2 – 11
- Feed Water Turbidity: ≤ 1 NTU
- Feed Water SDI (Silt Density Index): ≤ 5
- Backwash Pressure: 0.2 – 0.3 MPa
- Backwash Time: 45 – 75 seconds

Application
- Brackish Water Desalination: Actively treats brackish water sources, removing salts and impurities to produce potable water for domestic use and water suitable for industrial processes in areas where brackish water is abundant.
- Industrial Water Treatment: Used in industries such as power generation, electronics, and chemical manufacturing. In power generation, it purifies water for boiler feed, preventing scale formation and ensuring efficient operation. In electronics, it provides ultra – pure water for semiconductor manufacturing.
- Municipal Water Treatment: Incorporate into municipal water treatment plants to enhance the quality of source water, whether it’s surface water or well water. It helps meet the strict standards for public water supply, improving the overall drinking water quality for the community.
- Water Reuse and Recycling: Treats secondary or tertiary treated wastewater, removing remaining dissolved solids, organic matter, and salts. The treated water can be reused for non – potable applications like irrigation, industrial cooling tower makeup water, and toilet flushing, conserving freshwater resources.
