The LRFR series Fouling Resistant Reverse Osmosis membrane elements are specifically designed to handle source water with high fouling potential. Utilizing special membrane surface modification and flow channel design, they significantly reduce the rate of adsorption and deposition of pollutants such as organic matter, colloids, and microorganisms on the membrane surface. While maintaining high salt rejection (99.5%-99.8%), this series notably extends chemical cleaning intervals, reducing maintenance frequency and cost. It is a reliable choice for treating municipal wastewater, industrial effluent, surface water, and other challenging water qualities.
Excellent Fouling Resistance: Optimized surface properties and structure effectively resist organic, biological, and colloidal fouling, maintaining stable membrane flux over the long term.
Stable High Rejection Performance: Even when facing complex feed water, it maintains excellent salt rejection as high as 99.8%, producing consistently compliant, high-quality pure water.
Reduced Operational and Maintenance Costs: Longer cleaning cycles reduce chemical usage, downtime, and labor maintenance costs, improving overall system availability and economy.
Suitable for Challenging Water Sources: The preferred membrane element for wastewater reuse, surface water treatment, and desalination projects with high fouling potential feed water.
The LRFR series is designed for high-fouling-risk water sources. Its core applications include:
Municipal and Industrial Wastewater Advanced Treatment and Reuse (Reclaimed Water): Serves as the core desalination unit following MBR or UF, treating secondary effluent, resisting organic and microbial fouling to produce high-quality reuse water.
Surface Water (River, Lake Water) Purification: Directly treats surface water containing significant colloids, organic matter, and microorganisms to produce industrial or potable water, with more stable system operation.
Landfill Leachate Treatment Systems: Used for volume reduction treatment of leachate membrane concentrate. Its strong fouling resistance can handle extremely high COD and scaling ion loads.
Food, Paper, Textile, and Other Industry Process Water Recovery: Treats complex, high-organic-load process wastewater to recover water resources and reduce discharge.
