Key Features and Advantages
Modular Design for Flexibility
The LFRO-4 system is built with a modular approach, allowing easy expansion or customization based on project needs. Each component (e.g., sand filters,活性炭 filters) can be independently maintained or upgraded without disrupting the entire system.Multi-Stage Filtration
- Quartz Sand Filter: Removes suspended solids, silt, and particulate matter through mechanical filtration.
- Activated Carbon Filter: Reduces organic compounds, chlorine, and odors via adsorption.
- Anti-Scale Dosing System: Prevents mineral buildup on membranes using precision chemical injection.
- Security Filter: Protects RO membranes from fine particles (1–10 μm) using polypropylene cartridges.
High-Efficiency RO Membranes
Equipped with 4040 RO membranes, the LFRO-4 achieves a water recovery rate of up to 75%, minimizing waste water while maximizing pure water output. The membranes remove up to 99% of dissolved salts, bacteria, viruses, and heavy metals.Energy Efficiency
The system integrates a 1.1 kW high-pressure pump optimized for low energy consumption, coupled with smart pressure control to reduce power usage during operation.Intelligent Control System
A user-friendly control panel monitors water quality in real time via a conductivity meter and provides insights into system performance, pressure, and flow rates. Automated features include self-cleaning, chemical dosing, and emergency shutdowns.Long-Term Cost Savings
With a focus on reducing maintenance and replacement costs, the LFRO-4 uses long-lasting components (e.g., 2-year lifespan for RO membranes under optimal conditions) and requires minimal chemical interventions due to its advanced pre-treatment stages.

Product Structure
The LFRO-4 system comprises the following core components:
- Raw Water Tank: Stores incoming water and ensures consistent supply to the system.
- Raw Water Pump: Boosts water pressure for filtration processes.
- Quartz Sand Filter: Removes large particulates and turbidity.
- Activated Carbon Filter: Eliminates organic contaminants and residual chlorine.
- Anti-Scale Dosing System: Injects inhibitors to prevent mineral scaling.
- Security Filter: Guards against fine particles entering the RO membranes.
- High-Pressure Pump: Generates the necessary pressure (up to 225 PSI) for reverse osmosis.
- RO Membrane Module: Houses the semipermeable membranes for ultra-pure water production.
- Pure Water Tank: Stores treated water for immediate use or distribution.
Working Principle
- Pre-Treatment: Raw water undergoes mechanical filtration (sand and活性炭 filters) and chemical dosing (anti-scaling agents) to remove impurities and stabilize water quality.
- High-Pressure Filtration: Pressurized water (up to 150 PSI for LFRO-4) is forced through the RO membranes, where water molecules pass through tiny pores while salts, ions, and microorganisms are rejected.
- Post-Treatment: The permeate (pure water) is collected, while the concentrate (reject stream) is recycled or discharged. The system’s flow rate and pressure are continuously monitored to optimize performance.
Applications in the Petrochemical Industry
The LFRO-4 system is widely adopted in petrochemical plants due to its ability to handle high-salinity feedwaters (e.g., produced water from oil extraction) and remove toxic contaminants (e.g., benzene, heavy metals). Key applications include:
- Boiler Feedwater Treatment: Reduces TDS and hardness to prevent scaling and corrosion.
- Wastewater Reuse: Treats oily wastewater from refining processes for recycling.
- Hydrogen Production: Ensures ultra-pure water for electrolysis systems.
Applications in Other Industries
Beyond petrochemicals, the LFRO-4 is versatile for:
- Electronics: Produces deionized water for semiconductor manufacturing.
- Pharmaceuticals: Meets GMP standards for drug production and cleaning.
- Food & Beverage: Purifies water for beverage brewing and packaging.
- Municipal Water Treatment: Enhances drinking water quality by removing pathogens and excess salts.
