Conductivity Meter: Monitors product water quality in real-time.
Concentrate Valve: Adjusts concentrate flow to optimize recovery.
Self-Cleaning: Automatic flush function prevents membrane fouling.
Low Energy Consumption: Optimized pump design reduces energy costs.
Longevity: Membrane lifespan of 2–3 years with proper maintenance.
High Flow Capacity:
Handles up to 30 m³/h, suitable for large-scale industrial operations.
Reduces water waste with adjustable recovery rates (50–75%).
Cost Efficiency:
Direct replacement for existing systems, minimizing downtime and retrofit costs.
Low maintenance requirements (e.g., cartridge replacement every 7–15 days).
Robust Construction:
Corrosion-resistant materials (304 stainless steel, UPVC) ensure durability in harsh environments.
Modular design allows easy expansion or customization.
Compliance:
Meets FDA, NSF, and EU standards for food, pharmaceutical, and semiconductor applications.
Backed by ISO certifications for quality and environmental safety.
The Reverse Osmosis Equipment Model LFRO-30 is ideally suited for steel mill water treatment, addressing critical challenges:
Circulating Water Filtration:
Removes iron, scale, and particulates from cooling water systems, preventing equipment corrosion and scaling.
Ensures consistent water quality for blast furnaces, rolling mills, and other critical processes.
Wastewater Recirculation:
Polishes wastewater for reuse in non-contact cooling, reducing freshwater consumption.
Removes oils, greases, and suspended solids to meet discharge standards.
Boiler Feed Water:
Key Benefits for Steel Mills:
Sustainability: Reduces water intake and wastewater discharge.
Cost Savings: Lower freshwater and chemical treatment costs.
Process Reliability: Consistent water quality ensures stable production.
The LFRO-30 excels in diverse industries:
Food & Beverage: Purifies water for bottling, brewing, and cleaning.
Power Generation: Treats boiler feedwater and cooling water in thermal and nuclear plants.
Chemical Processing: Provides ultra-pure water for pharmaceutical and petrochemical applications.
Municipal Water Treatment: Produces potable water from brackish or contaminated sources.
The LFRO-30 operates on the principle of reverse osmosis, where feedwater is forced through a semipermeable membrane under pressure:
Pre-Treatment:
Multi-media and activated carbon filters remove particulates, organics, and chlorine.
Anti-scale dosing prevents mineral precipitation.
Reverse Osmosis:
High-pressure pump drives feedwater through RO membranes, separating contaminants from purified water .
Membranes reject dissolved solids, colloids, and microorganisms, producing water with <10 ppm TDS.
Post-Treatment:
LEFILTER’s Reverse Osmosis Equipment Model LFRO-30 combines cutting-edge technology, durability, and cost efficiency to deliver superior water purification for industrial applications. Whether used in steel mills, power plants, or food processing facilities, this system ensures reliable, high-quality water while reducing environmental impact and operational costs.
