The Ro Components Industrial Membrane 4" SERIES is a high-performance reverse osmosis membrane designed for industrial water purification applications. Engineered to operate under stringent conditions, this membrane delivers efficient desalination and contaminant removal from feed water with a remarkable recovery rate of 15% per single element. It is tested rigorously at 150 psi testing pressure and 25°C with a 1500 ppm NaCl solution at pH 7.5 to ensure consistent performance and durability. The membrane supports a maximum working pressure of up to 600 psi (4.14 Mpa) and can handle feed water temperatures up to 45°C, making it suitable for a variety of industrial process water and wastewater treatment scenarios. The maximum feed water volume capacity is 16 gallons per minute (gpm), with a specific capacity of 8 gpm for the 4021 model variant. Ideal for continuous operations, this membrane accommodates a pH range from 3 to 10 during operation and a wider pH range from 2 to 12 for chemical cleaning procedures, ensuring extended membrane life and performance robustness. Additionally, it requires feed water with residual chlorine concentration lower than 0.1 ppm to prevent membrane degradation. Pressure drop limits are optimized for system integration, with a maximum pressure drop of 15 psi per single membrane element and 50 psi per vessel housing up to six membranes. The Ro Components Industrial Membrane 4" SERIES represents a reliable choice for manufacturers and industrial enterprises seeking to enhance their water purification capabilities efficiently and sustainably.
