Features and Advantages
1. High Efficiency with Low Energy Consumption
LEFILTER’s RO systems operate at 15–20% lower pressure than conventional setups, reducing energy costs without compromising flux rates. Advanced polyamide thin-film composite (TFC) membranes ensure superior contaminant rejection while maintaining high throughput.
2. Modular and Scalable Design
Systems are pre-engineered for easy integration into existing infrastructure. Scalable configurations allow capacity expansion by adding membrane modules, making them ideal for growing operations.
3. Durability and Chemical Resistance
Reinforced Components: Stainless steel or UPVC piping resists corrosion and abrasion.
Anti-Scaling Technology: Integrated dosing systems inject scale inhibitors to prolong membrane life.
Wide pH Tolerance: Compatible with aggressive cleaning agents (e.g., citric acid, sodium hydroxide).
4. Sustainability
High Recovery Rates: Minimize wastewater discharge, aligning with environmental regulations.
NSF/ANSI 61 Certified: Safe for potable water applications.
Product Structure
LEFILTER’s RO systems feature a multi-stage architecture for optimal performance:
Pre-Treatment Unit:
Raw Water Tank: Stores untreated water (user-provided).
Multimedia Filter: Removes suspended solids via graded quartz sand layers.
Activated Carbon Filter: Adsorbs chlorine, organics, and odors.
Antiscalant Dosing System: Prevents membrane fouling.
Security Filter: 5–40 μm polypropylene cartridges protect downstream components.
High-Pressure Pump: Stainless steel centrifugal pump delivers feedwater to RO membranes.
RO Membrane Array:
Pressure Vessels: Stainless steel or fiberglass housings.
Spiral-Wound Membranes: TFC polyamide membranes for selective separation.
Post-Treatment:
UV Sterilizer/Deionizer: Optional polishing for ultra-pure water.
Pure Water Tank: Stores treated water (user-provided).
Working Principle
The RO process leverages semi-permeable membranes and high pressure to purify water:
Pre-Treatment: Feedwater passes through multimedia and carbon filters to remove particulates, chlorine, and organics.
Pressurization: A high-pressure pump drives water into RO membranes at 15–40 bar.
Separation:
Permeate: Pure water molecules pass through membrane pores.
Concentrate: Contaminants are flushed away as brine.
Post-Treatment: Permeate is optionally sterilized or deionized before storage.
Model Range
LEFILTER offers 14 standardized models (LFRO-0.5 to LFRO-50) with flow rates from 0.5 to 50 m³/hr, catering to small facilities to large industrial plants. Custom configurations are available for specialized needs.
Applications in Coal Mining Water Treatment
Coal mining operations generate wastewater laden with heavy metals, suspended solids, and sulfates. LEFILTER’s RO systems address these challenges:
Heavy Metal Removal: Eliminates lead, arsenic, and mercury to meet discharge standards.
Sulfate Reduction: Treats acid mine drainage (AMD) for safe reuse or discharge.
Closed-Loop Systems: Recovers up to 80% of process water, reducing freshwater intake.
Case Study:
A coal mine in Shanxi, China, integrated LFRO-10 systems to treat 10 m³/hr of acidic wastewater. Results included:
90% reduction in sulfate concentrations.
60% lower sludge disposal costs due to reduced chemical usage.
Applications in Other Industries
1. Power Generation
Boiler Feedwater: Removes silica and hardness ions to prevent turbine scaling.
Flue Gas Desulfurization (FGD): Purifies limestone slurry water for efficient scrubbing.
2. Food & Beverage
