5. Application Procedures

Combined with years of practical industrial application experience, the application procedures of BW30FR-4040 are standardized and operable, ensuring safe and efficient operation. Pre-installation preparation: Check the integrity of the membrane element, confirm that the surface, sealing ring and end plate are not damaged; check the quality inspection report to ensure that the parameters meet the requirements; clean the system pipeline and membrane housing, remove impurities such as rust and sediment, and prepare installation tools (wrench, screwdriver) and professional water quality monitoring instruments. Membrane element installation: Install it into the industrial-grade pressure vessel according to the correct direction (water inlet and outlet cannot be reversed), ensure that the connection is tight, and install the sealing ring and connecting adapter correctly to prevent water leakage; the membrane element is suitable for series connection of three or more in each pressure vessel, which can withstand higher operating pressure drop. System commissioning: Turn on the power and water source, adjust the pressure to the recommended value (0.8-1.8MPa), adjust the flow rate and recovery rate, run the system for 30-60 minutes, and check whether the desalination rate, flux and other parameters meet the requirements. Normal operation: Regularly monitor the operating parameters (pressure, flux, desalination rate, SDI), and keep detailed records; if the pressure increases by 0.10MPa or the flux decreases by 15%, clean it in time. Membrane cleaning: Use professional acidic or alkaline cleaning solution according to the pollution type, circulate and clean at 25-35℃ for 30-60 minutes, rinse with clean water until neutral, then restart. Daily maintenance: After the system is shut down, rinse the membrane element for 5-10 minutes; regularly check the sealing ring and end plate, avoid long-term contact with strong oxidants (inlet water residual chlorine ≤0.1mg/L), and properly store it in 1.0% sodium bisulfite protective solution when not in use for a long time.

7. Working Principle

BW30FR-4040 realizes high-precision water purification and anti-pollution performance based on the reverse osmosis principle, combined with advanced membrane material modification technology and optimized spiral wound structure. The spiral wound structure is composed of multiple leaf membrane bags, each of which is composed of two membrane sheets with opposite front sides, a product water flow channel between the two membrane sheets, and a turbulent grid-shaped inlet water flow channel placed on the membrane surface; the three sides of the membrane bag are sealed with adhesive, and the fourth side is open on the perforated product water collection pipe, which has the advantages of uniform water flow distribution and strong anti-pollution ability. Osmosis is a natural phenomenon in which water molecules spontaneously flow from a low concentration solution to a high concentration solution. Reverse osmosis applies a pressure greater than the osmotic pressure (0.8-1.8MPa) on the high concentration side (raw water side), forcing water molecules to pass through the semi-permeable membrane (pore size only 0.1 nanometers) to the low concentration side (produced water side), while retaining salts, heavy metals, colloids and other harmful substances. The modified aromatic polyamide composite membrane of BW30FR-4040 has a dense and uniform surface structure, which ensures high desalination rate and purification efficiency; the special anti-fouling coating reduces the adsorption of pollutants, and the 34mil wide inlet water mesh reduces flow resistance and concentration polarization, slows down membrane fouling, ensuring stable operation of the membrane element in high-pollution water quality environments.
