The LRULP series Ultra-Low Pressure Reverse Osmosis membrane elements represent the advanced level of high-efficiency, energy-saving desalination technology. This series is specifically designed to achieve high water production and high salt rejection at significantly reduced operating pressures, potentially helping systems lower energy consumption by 20-40%. With their excellent separation performance, wide applicability, and superior fouling resistance, the LRULP series is an ideal core component for projects involving high-quality pure water production, brackish water desalination, and wastewater reuse, providing customers with an economical and sustainable desalination solution.
Revolutionary Energy-Saving Performance: As an Ultra-Low Pressure (ULP) series, its innovative membrane elements achieve rated water production at much lower feed pressures compared to standard RO membranes, significantly reducing system operating energy and pumping costs.
Excellent and Stable Rejection Performance: Provides stable salt rejection as high as 99.0%-99.6%, effectively removing dissolved salts, ions, organic matter, bacteria, and viruses from water. Product water quality meets the most stringent application standards.
High Flux and High Water Production: Optimized membrane area and flow channel design ensure high water flux even at low pressures. Single-element water production covers a wide range (2,000 to 12,650 GPD), offering flexible selection.
Excellent Chemical Stability and Fouling Resistance: The membrane material features a good pH tolerance range, allowing effective chemical cleaning to restore performance and extend service life.
The LRULP series Ultra-Low Pressure Reverse Osmosis membrane elements are key to achieving high-purity water and wastewater minimization, widely used in:
Ultrapure Water (UPW) for Electronics and Power Industry: Serves as the core desalination unit, providing megohm-level high-purity water for semiconductor chip manufacturing, LCD panel production, and high-pressure boilers.
Food, Beverage, and Pharmaceutical Water: Produces sterile, ion-interference-free process water or ingredient water, ensuring product quality and safety.
Municipal and Community Drinking Water Purification: Efficiently removes salts, heavy metals, and harmful substances from brackish or contaminated sources, producing safe, compliant drinking water.
Seawater and Brackish Water Desalination: Converts seawater or high-salinity brackish water into quality freshwater with low energy consumption, suitable for islands, coastal areas, and inland water-scarce regions.
Industrial Wastewater Zero Liquid Discharge (ZLD) and Reuse: Performs advanced desalination and concentration on industrial wastewater. The product water can be reused in production processes, reducing freshwater intake and wastewater discharge.
Choosing the LRULP series means choosing an efficient, reliable, and low-operational-cost desalination solution. We can provide professional selection support and system design services based on your source water quality and product water requirements.
