China Reverse Osmosis System for Drinking Water - Top Suppliers & Factory Direct Purification Solutions

Reverse osmosis (RO) is an advanced water purification technology utilized by top China suppliers and factories to effectively eliminate impurities such as dissolved salts, organic materials, and bacteria from water sources. This innovative system operates on the principle of applying pressure to enable water molecules to pass through a semi-permeable reverse osmosis membrane (RO membrane) with a pore size of 1/10,000 μm. As a result, harmful pollutants are retained, ensuring that the water meets stringent physical and chemical standards suitable for drinking. The water produced through reverse osmosis technology boasts the highest purity levels available, achieving a remarkable cleanliness level of almost 100%. Choose our China suppliers for reliable and efficient RO water purification solutions.

    Products Description

    RO equipment is currently one of the most advanced systems for producing pure water in global water treatment technology. It features low operating costs, economic efficiency, ease of operation, and reliable performance, making it the preferred choice for businesses requiring pure water production. The production capacity of RO equipment is based on raw water at 25°C, which represents the standard production condition. Variations in water temperature and production conditions may influence the equipment's output capacity.

    Industrial reverse osmosis equipment must be configured with different processes according to specific water quality requirements. Water standards vary across industries, such as resistivity levels ranging from 18 MΩ·cm to 0.5 MΩ·cm and conductivity ranging from 20 μS/cm to 0.1 μS/cm. Therefore, it is essential to configure appropriate pretreatment systems, single-stage or double-stage reverse osmosis processes, and post-treatment systems (e.g., EDI electric demineralization systems, polishing mixed bed systems, ultraviolet sterilization, ozone generators, chlorine dioxide systems, etc.) to meet these diverse standards.

    Major Components

    1. Pretreatment System
    • Multi-media Filter: Removes suspended solids, sediments, and other large particulate impurities.
    • Activated Carbon Filter: Adsorbs organic compounds, residual chlorine, odors, and other contaminants.
    • Softener: Eliminates calcium and magnesium ions from water to prevent scale formation.
    2. Reverse Osmosis Membrane
    Core component, typically constructed of polyamide or cellulose acetate materials, with an extremely small pore size (approximately 0.0001 microns). It effectively intercepts dissolved salts, bacteria, viruses, and other microorganisms.
    3. High-Pressure Pump
    Supplies sufficient pressure (generally ranging from 100 to 1000 psi) to enable water molecules to permeate through the reverse osmosis membrane.
    4. Post-treatment System
    • UV Sterilizer: Provides additional sterilization by eliminating bacteria and viruses.
    • Ozone Generator: Utilized for disinfection and odor removal processes.
    5. Control System
    • PLC Controller: Automates equipment operation and monitors parameters such as pressure, flow rate, and water quality.
    • Instruments: Devices such as pressure gauges, flow meters, and conductivity meters are employed for real-time monitoring and data collection.

    Frequently Asked Questions

    What is the optimal water temperature for reverse osmosis equipment?
    The optimal design water temperature for the reverse osmosis unit is between 20°C and 25°C. Variations in water temperature and production conditions may influence the equipment's overall output capacity.
    What impurities can the RO membrane filter out?
    The RO membrane has an extremely small pore size of approximately 0.0001 microns, allowing it to effectively intercept dissolved salts, organic impurities, bacteria, viruses, and other microorganisms to produce highly pure water.
    Why is a pretreatment system necessary for RO equipment?
    The pretreatment system (including multi-media filters, activated carbon filters, and softeners) removes suspended solids, organic compounds, residual chlorine, and calcium/magnesium ions. This prevents scaling and fouling on the reverse osmosis membrane, extending its lifespan.
    What are the feed water requirements for the RO system?
    Key feed water requirements include: pH of 4~11 during operation, Turbidity < 1.0 NTU, Silt Density Index (SDI) < 5, Free residual chlorine < 0.1 mg/L, and water temperature between 5°C and 45°C.
    What industries utilize industrial reverse osmosis equipment?
    RO equipment is widely applied in water treatment, electronics, chemicals, pharmaceuticals, food and beverages, metallurgy, and environmental protection sectors.
