After decades of development, China’s RO plant manufacturing industry has established a complete industrial chain system. Many companies have enhanced product competitiveness by combining imported advanced technologies with independent innovation. These enterprises integrate R&D, production, sales, engineering installation, and after-sales service, with products widely applied in desalinizaci\u00f3n de agua de mar<\/strong><\/a><\/span>, drinking water purification<\/strong><\/a>, industrial water treatment<\/strong><\/a><\/span>, and wastewater reuse.<\/p>\n

China’s RO plant manufacturers have evolved from an initial phase of imitation and learning to one where they can independently develop innovative technologies. Many companies have become primary agents or distributors for internationally renowned brands (e.g., Toray Membrane, Hydranautics, Dow, SK, Huitong Yuanquan) while actively developing their own brands. The industry as a whole exhibits a development trend combining internationalization with localization to meet diverse market demands.<\/p>\n

RO Plant Fundamentals: Reverse Osmosis Technology<\/strong><\/span><\/h2>\n

Reverse Osmosis (RO) is a water treatment technology that utilizes semi-permeable membrane technology to separate impurities from water by applying pressure. The core component of RO equipment is the RO membrane, featuring a pore size of approximately\u00a00.0001 microns<\/strong>\u2014equivalent to one-millionth the diameter of a human hair\u2014effectively removing dissolved salts, colloids, microorganisms, and organic matter from water.<\/p>\n

The technological evolution of RO membranes<\/strong>\u00a0has progressed through multiple stages: from the 1959 development of the first synthetic RO membrane with an asymmetric structure (L-S membrane) by Sorilla and Rob, to the 1979 patent application by Cardot for the interfacial polymerization method to produce RO membranes, which established the standard manufacturing process for modern commercial spiral-wound RO membranes. RO membranes produced via interfacial polymerization comprise three layers: a base layer (nonwoven fabric) + a support layer (polysulfone) + a separation\/desalination layer (polyamide).<\/p>\n

Based on application scenarios, RO plant falls into three major categories: Residential<\/strong>\u00a0(50-400 gallons\/day),\u00a0Commercial<\/strong>, and\u00a0Industrial<\/strong>. Industrial RO system<\/a>s<\/strong> <\/span>handle large water volumes with stringent quality requirements, widely used in electronics, pharmaceuticals, and chemical industries.<\/p>\n

Components and Functions of RO plant<\/strong><\/span><\/h2>\n

A complete RO system comprises multiple precision components, each serving a specific purpose:<\/p>\n

    \n
  • Sistema de pretratamiento<\/strong>: Includes PP cotton filters and activated carbon filters. PP cotton with pore sizes of 5 microns or 1 micron performs initial filtration, removing particulates like sand, rust, and silt from the source water. Activated carbon filters further adsorb residual contaminants, pesticides, fertilizers, organic compounds like trichloromethane, and other substances missed by the previous stage.<\/li>\n
  • High-Pressure Pump<\/strong>: Supplies the pressure required for the RO membrane to function properly, typically operating between 70-100 PSI (0.5-0.7 MPa). The high-pressure pump is the heart of the RO system, providing the driving force for the reverse osmosis process.<\/li>\n
  • RO Membrane Assembly<\/strong>: The core component of the system, categorized by capacity as 50G, 75G, 100G, 200G, 300G, etc. (G denotes gallons per day). RO membranes effectively remove minute impurities, salts, organic compounds, undesirable minerals, heavy metals, viruses, bacteria, and other harmful substances from water.<\/li>\n
  • Pressure Tank<\/strong>: Stores purified water. Empty tanks maintain 6-8 PSI pressure. Available in 1.5G, 2G, 3.2G, 4G, 11G, 20G capacities. Standard residential units (50G, 75G, 125G, 300G, 400G) typically use 3.2G tanks; larger tanks are reserved for commercial systems.<\/li>\n
  • Sistema de control<\/strong>: Includes high\/low-pressure switches and solenoid valves. The high-pressure switch prevents the pump from running at full speed, while the low-pressure switch prevents the pump from running dry.<\/li>\n<\/ul>\n

    How does RO plant Work?<\/strong><\/span><\/h2>\n

    The operating principle of RO equipment is based on the\u00a0physical processes of osmosis and reverse osmosis<\/strong>.<\/p>\n

    In natural osmosis, water molecules migrate through a semipermeable membrane from the side with lower solute concentration to the side with higher solute concentration until equilibrium is reached. Reverse osmosis, however, applies pressure (0.5 to 15 MPa, varying based on water quality requirements) to the high-solute-concentration side. This forces water molecules to flow in the opposite direction through the semipermeable membrane\u2014from the high-concentration side to the low-concentration side\u2014effectively filtering out dissolved solids and impurities.<\/p>\n

    The specific workflow can be divided into four stages:<\/p>\n

      \n
    1. Feed Water Treatment<\/strong>: Raw water passes through a pretreatment system to remove suspended solids, large particulate impurities, residual chlorine, etc.<\/li>\n
    2. Pressurization Process<\/strong>: A high-pressure pump pressurizes the water to a pressure exceeding osmotic pressure.<\/li>\n
    3. Filtration Separation<\/strong>: Water molecules pass through the RO membrane, while impurities are retained and discharged with the concentrate.<\/li>\n
    4. Product Water Collection<\/strong>: Purified water is collected, while concentrate is discharged through the drainage system.<\/li>\n<\/ol>\n

      RO systems exhibit exceptionally high\u00a0removal efficiency<\/strong>: Total Dissolved Solids (TDS) removal rates reach 95%-99%, bacterial and viral removal exceeds 99%, and heavy metal removal exceeds 95%. In contrast, traditional filtration systems achieve only approximately 40%-60% TDS removal.<\/p>\n

            Frequently Asked Questions (FAQ)<\/strong><\/span><\/h2>\n

            1. What is the lifespan of RO plant?<\/strong>\u00a0RO membranes typically last 2-3 years. Pre-filters (PP cotton and activated carbon cartridges) should be replaced every 3-6 months, depending on local water quality.<\/p>\n

            2. Why does RO plant produce wastewater?<\/strong>\u00a0The reverse osmosis process requires expelling concentrated impurities to ensure stable system operation. The wastewater ratio depends on the source water quality and RO membrane performance, typically ranging from 1:1 to 1:3 for purified water to wastewater.<\/p>\n

            3. How can I tell when the RO membrane needs replacement?<\/strong>\u00a0When the TDS value of purified water significantly increases or the RO membrane’s removal efficiency decreases, it may be time for replacement. A normal RO membrane should achieve a salt rejection rate between 95% and 99%.<\/p>\n

            4. Is water treated by RO plant suitable for direct consumption?<\/strong>\u00a0Yes. RO systems effectively remove harmful substances like bacteria, viruses, and heavy metals, making the filtered water safe for drinking.<\/p>\n

            5. How to resolve insufficient pure water flow in RO plant?<\/strong>\u00a0Possible causes include clogged pre-filters or RO membrane, high-pressure pump failure, or insufficient pressure tank pressure. Regular replacement of pre-treatment filters and system pressure checks are key to maintaining flow rates.<\/p>\n
