4000 LPH Reverse Osmosis System – Industrial Water Purification The 4000 LPH reverse osmosis system is an industrial water purification solution designed to remove dissolved salts, minerals, and impurities from feed water using membrane separation technology. This system focuses only on the reverse osmosis process and does not include pretreatment equipment. Therefore, it works best where pretreatment is already installed or supplied separately. Because of its high output and stable operation, this reverse osmosis system suits demanding commercial and industrial applications that require consistent water quality. How the 4000 LPH Reverse Osmmosis System Works First, feed water enters the reverse osmosis system under controlled pressure. Then, a high-pressure pump forces the water through semi-permeable RO membranes. As a result, dissolved salts, contaminants, and unwanted particles remain on the reject side, while clean water passes through as product water. Meanwhile, built-in monitoring instruments allow operators to track pressure and flow. Therefore, the system maintains stable performance and protects the membranes during operation. Key Features of the Reverse Osmosis System The 4000 LPH reverse osmosis system combines performance and durability. In addition, it uses industrial-grade components to ensure long service life. Key features include: High water output of 4000 litres per hour Strong salt and TDS removal Stable operating pressure for membrane protection Industrial-grade electrical and control components Simple operation and easy maintenance System Configuration and Components This reverse osmosis system includes carefully selected components that work together for reliable purification. As a result, the system delivers consistent water quality under continuous operation. Core Components High-pressure pump for membrane operation Reverse osmosis membranes for salt removal Pressure gauges and switches for monitoring Flow meters for product and wastewater Electrical control panel for system operation Because the system does not include pretreatment, proper upstream filtration is required to protect the membranes. Technical Specifications – 4000 LPH Reverse Osmosis System Electrical and Power Power Supply: 8 kW Voltage: 380 V Frequency: 50 Hz Phase: 3 Phase Water Quality Requirements To ensure reliable performance, the following feed water limits apply: Feed Water TDS: < 3000 ppm Product Water TDS: < 50 ppm (first-stage RO) Chlorine Concentration: < 0.1 ppm Silt Density Index (SDI): < 5 Turbidity: < 1 NTU Acceptable pH Range: 3 – 10 These limits help protect the membranes and improve system lifespan. Operating Conditions Operating Pressure: < 13 bar (first-stage) Feed Pressure: 2 – 3 bar Minimum Feed Flow: ≥ 7 TPH Recovery Rate: 60% Therefore, the system balances water output and efficiency during operation. Temperature Limits Operating Temperature Range: 10 – 45 °C However, operating outside this range may reduce performance or membrane life. Performance Reference Conditions All performance values are based on: Feed Water Temperature: 25 °C Feed Water TDS: 3000 mg/L As a result, actual performance may vary depending on site conditions. Applications of the 4000 LPH Reverse Osmosis System This reverse osmosis system is suitable for: Industrial water purification Food and beverage processing Bottled water production (with pretreatment) Manufacturing facilities Commercial water treatment systems Because of its capacity and reliability, it performs well in continuous-use environments. Installation Notes This product is a reverse osmosis system only. Therefore, pretreatment such as multimedia filtration, carbon filtration, or antiscalant dosing must be supplied separately based on feed water analysis. A full water analysis is recommended before installation to ensure correct system sizing and long membrane life. Why Choose This Reverse Osmosis System The 4000 LPH reverse osmosis system delivers dependable water purification while maintaining simple design and industrial durability. In addition, it integrates easily with existing pretreatment setups. As a result, it offers a flexible and efficient solution for large-scale water purification needs.
