​Introduction​

In the realm of advanced water treatment technologies, ​Reverse Osmosis (RO)​ stands out as a cornerstone for producing ultra-pure water. The ​LFRO-4 Reverse Osmosis System​ by Xinxiang Lifeierte Filter Corp. is designed to meet the rigorous demands of industries requiring high-quality water with minimal energy consumption and operational complexity. This compact, modular system combines state-of-the-art filtration, chemical dosing, and membrane technology to deliver exceptional performance, making it an ideal choice for both small-scale and large-scale applications.


​Product Specifications​

The ​LFRO-4​ system is engineered to handle a flow rate of ​0.5 m³/hr​ (132 gallons per day), making it suitable for projects requiring moderate to high water purity. Below are the key technical specifications:

​Component​​Specification​
​Raw Water Pump​BW2-4 (0.55 kW)
​Quartz Sand Filter​Size: 250×1400 mm
​Activated Carbon Filter​Size: 250×1400 mm
​Anti-Scale Dosing System​Capacity: 40L
​Security Filter​5×20″ Cartridge Type
​High Pressure Pump​BL2-11 (1.1 kW)
​Reverse Osmosis Membrane​2×RO Membrane 4040
​Pipe Material​UPVC (Stainless Steel optional)

​Key Features and Advantages​

  1. ​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.

  2. ​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.
  3. ​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.

  4. ​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.

  5. ​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.

  6. ​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:

  1. ​Raw Water Tank: Stores incoming water and ensures consistent supply to the system.
  2. ​Raw Water Pump: Boosts water pressure for filtration processes.
  3. ​Quartz Sand Filter: Removes large particulates and turbidity.
  4. ​Activated Carbon Filter: Eliminates organic contaminants and residual chlorine.
  5. ​Anti-Scale Dosing System: Injects inhibitors to prevent mineral scaling.
  6. ​Security Filter: Guards against fine particles entering the RO membranes.
  7. ​High-Pressure Pump: Generates the necessary pressure (up to 225 PSI) for reverse osmosis.
  8. ​RO Membrane Module: Houses the semipermeable membranes for ultra-pure water production.
  9. ​Pure Water Tank: Stores treated water for immediate use or distribution.

​Working Principle​

  1. ​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.
  2. ​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.
  3. ​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.
