Fully Automatic Reverse Osmosis Equipment with Water tank for Reducing Salinity and Softening Water Quality

Product description

Key Components and Functions

1. Pre-Filtration System
   • Sediment Filter: Removes large particles (e.g., sand, rust, silt) to protect downstream components.
   • Activated Carbon Filter: Reduces organic compounds, chlorine, odors, and 色度 (color) to improve water taste and protect the RO membrane.
   • Softening Unit (Optional): Uses ion exchange resin to remove calcium and magnesium ions, reducing water hardness and preventing membrane scaling.
2. Reverse Osmosis Membrane Module
   • RO Membrane: A semipermeable membrane with pore sizes as small as 0.0001 microns, effectively removing dissolved salts (e.g., NaCl), heavy metals (e.g., lead, arsenic), bacteria, viruses, and other contaminants.
   • High-Pressure Pump: Generates the pressure required to force water through the RO membrane against the osmotic pressure.
3. Automatic Control System
   • PLC/Touchscreen Controller: Manages the entire process, including startup/shutdown, flushing cycles, and fault detection.
   • Sensors: Monitor parameters like inlet/outlet pressure, flow rate, conductivity, and pH to ensure optimal performance.
   • Automatic Flushing: Periodically flushes the RO membrane to prevent pollutant accumulation and extend membrane life.
4. Storage Water Tank
   • Food-Grade Polyethylene Tank: Stores treated water for continuous use, with a capacity ranging from 100 liters to several cubic meters (customizable based on demand).
   • Level Sensors: Automatically control water inflow/outflow to maintain tank levels and prevent overflow or dry running.
5. Post-Treatment (Optional)
   • UV Sterilizer: Eliminates residual bacteria or viruses in the treated water.
   • Mineral Addition Unit: Adds beneficial minerals (e.g., calcium, magnesium) if desired for drinking water applications.

Working Principle

1. Pre-Treatment: Water passes through sediment and carbon filters to remove physical and organic contaminants. If included, the softening unit reduces hardness by exchanging calcium/magnesium ions with sodium ions.
2. Reverse Osmosis: Pressurized water flows through the RO membrane, where dissolved salts and impurities are retained as concentrate (brine), while purified water (permeate) is collected.
3. Concentrate Disposal: The reject water (concentrate) is discharged or recycled (e.g., for non-potable uses), with a recovery rate typically between 70–90% (depending on water source and system design).
4. Storage and Distribution: Treated water is stored in the tank and supplied on demand, with the automatic system ensuring a steady flow and pressure.

Technical Specifications (Typical)

Applications

• Residential/Commercial: Producing drinking water, reducing scaling in plumbing systems, and improving appliance lifespan (e.g., water heaters, boilers).
• Industrial: Water for manufacturing processes (e.g., pharmaceuticals, electronics, cosmetics), cooling towers, and boiler feedwater.
• Marine/RV: Seawater desalination for ships, yachts, or recreational vehicles.
• Agriculture: Irrigation water for crops sensitive to high salinity or hardness.

Advantages

1. Fully Automatic Operation: Reduces manual labor and human error, with real-time monitoring and self-adjustment.
2. High Efficiency: Low energy consumption (especially with energy recovery devices for seawater systems) and high water recovery rates.
3. Durability: Corrosion-resistant materials and long-lasting RO membranes (replaceable every 3–5 years with proper maintenance).
4. Flexibility: Customizable for different water sources (brackish water, well water, seawater) and output requirements.
5. Cost-Effective: Lower long-term costs compared to bottled water or chemical softening methods.

Maintenance and Care

• Regular Filter Replacements: Sediment and carbon filters should be replaced every 3–6 months (depending on water quality).
• Membrane Cleaning: Chemical cleaning as needed to remove organic/inorganic fouling (e.g., every 6–12 months).
• System Checks: Periodic inspection of pumps, valves, and sensors to ensure leak-free operation and optimal performance.

Compliance and Standards

• Meets international standards for drinking water (e.g., WHO, NSF/ANSI 58 for RO systems).
• CE certification available for European markets; other regional certifications (e.g., UL, CSA) can be obtained upon request.
