Activated Carbon Filter: Adsorbs organic compounds, chlorine, and odors.
Anti-Scale Dosing System: Prevents membrane scaling with precise chemical injection.
Security Filter: 5-micron polypropylene cartridges protect downstream components.
Core Components:
High-Pressure Pump (CDM85-60): Delivers 45KW power to drive water through RO membranes.
RO Membrane Array: 50×8040 spiral-wound polyamide membranes for high-efficiency separation.
Stainless Steel/UPVC Piping: Corrosion-resistant and durable fluid pathways.
Post-Treatment & Control:
Pure Water Tank: Stores treated water (user-provided).
Control Panel: Monitors pressure, flow rates, and water quality (TDS, conductivity).
Automated Valves & Sensors: Ensure safe operation with real-time adjustments.
Application in Sewage Treatment Plants
The LFRO-50 is pivotal for municipal and industrial sewage treatment, addressing critical challenges:
Wastewater Reclamation: Removes heavy metals, pathogens, and dissolved organics from industrial effluents.
Zero Liquid Discharge (ZLD): Concentrates contaminants into a minimal waste stream for eco-friendly disposal.
Case Study: A sewage plant in Henan Province achieved 95% water recovery using LFRO-50, reducing operational costs by 30% through reduced sludge disposal.

Other Industry Applications
Desalination: Converts seawater into potable water for coastal communities.
Chemical Manufacturing: Purifies process water for high-purity chemical synthesis.
Power Generation: Treats boiler feed water to prevent scaling in turbines.
Food & Beverage: Ensures compliance with hygiene standards for production water.
Pharmaceuticals: Provides USP-grade water for drug formulation.
Key Advantages
High Efficiency:
≥99% rejection rate for dissolved solids, bacteria, and viruses.
50 m³/hr output with optimized energy consumption (45KW pump).
Durability:
Stainless steel/UPVC construction resists corrosion and extends lifespan.
Automated backwash prolongs pre-filter media life.
Cost Savings:
Modular design reduces installation and maintenance costs.
Low chemical consumption due to anti-scale dosing precision.
Compliance: Meets ISO, CE, and FDA standards for global deployment.
Working Principle
Pre-Treatment:
Raw water passes through sand and carbon filters to remove particulates and organics.
Anti-scale chemicals are injected to inhibit membrane fouling.
Reverse Osmosis:
High-pressure pumps force water through semi-permeable RO membranes.
Contaminants (ions, microbes) are rejected and flushed as concentrate.
Purified water (permeate) is collected for use.
Post-Treatment:
Treated water is stored in tanks, with quality monitored via conductivity sensors.
