Welcome: Yiwu Weihao Machinery Equipment Company
As a leading manufacturer of water treatment equipment, Yiwu Weihao Machinery Equipment Company specializes in designing and manufacturing **RO Membrane Systems for Water Purification**—high-efficiency, integrated reverse osmosis membrane solutions tailored for various water purification scenarios (drinking water, commercial, industrial pure water). Centered on high-performance RO membrane technology, this system efficiently removes impurities, salt ions, bacteria, viruses, organic pollutants, and heavy metals from raw water (tap water, groundwater, surface water), producing high-purity water that meets drinking, commercial, and industrial standards. It features stable performance, easy operation, and energy-saving advantages, making it the core equipment for residential, commercial, and industrial water purification projects.
Compared with traditional water purification methods (filtration, distillation), our RO membrane system for water purification has higher purification precision, better water quality stability, and lower energy consumption. It can adapt to different raw water quality, solving the problems of impure water quality, harmful substances exceeding standards, and unstable water supply for households, enterprises, and institutions.
The RO Membrane System for Water Purification achieves high-efficiency water purification through a scientific, multi-stage workflow, with high-performance RO membrane as the core, adapting to different raw water purification needs:
Raw Water Intake & Pretreatment: Raw water (tap water, groundwater, surface water) is collected and filtered through sediment filter, activated carbon filter, and precision filter to remove suspended solids, sediment, residual chlorine, organic matter, and large-particle impurities. This step protects the RO membrane from fouling, scaling, and damage, ensuring the membrane’s long-term stable operation.
Water Softening (Optional): For high-hardness raw water, a softening device is added to remove calcium, magnesium ions, reducing scaling substances and avoiding membrane blockage, extending the membrane’s service life.
High-Pressure Pumping: The pretreated raw water is pressurized by a high-pressure pump to reach the operating pressure required for RO membrane purification (15–40 bar), ensuring efficient separation of water molecules and impurities.
RO Membrane Purification (Core Process): Pressurized raw water flows through high-performance RO membranes (hollow fiber or spiral wound), which allow water molecules to pass through while blocking salt ions, bacteria, viruses, heavy metals (lead, arsenic, mercury), and organic pollutants, realizing deep purification of water.
Post-Treatment: The purified high-purity water is treated by activated carbon filtration, UV disinfection, or mineralization (for drinking water) to improve water taste and ensure water quality safety, meeting relevant standards.
Concentrate Discharge: The concentrated water (after RO membrane treatment) is discharged or recycled (for flushing, irrigation), realizing rational use of water resources and avoiding waste.
Integrated Control: The entire system is controlled by a PLC touch screen (for commercial/industrial models) or intelligent controller (for residential models), realizing automatic operation, real-time monitoring of water quality, flow, and membrane performance, with automatic flushing and fault alarm functions.
High Purification Precision: Adopts high-performance RO membranes (rejection rate up to 99.8%+), effectively removing salt ions, bacteria, viruses, heavy metals, and organic pollutants; purified water TDS ≤ 50 ppm, meeting WHO drinking water standards and industrial pure water requirements.
Strong Adaptability: Suitable for various raw water types (tap water, groundwater, surface water), adaptable to different water quality (TDS 100–5,000 ppm), with stable purification effect in different regions and scenarios.
High-Quality RO Membrane: Uses imported or high-grade domestic RO membranes, with good anti-fouling, anti-scaling performance, and long service life (2–5 years), reducing replacement costs.
Energy-Saving & Efficient: Optimized high-pressure pump and energy recovery device (for large-scale systems), reducing energy consumption by 20–30% compared with traditional RO systems; continuous water production, high water yield (60–80%).
Easy Operation & Maintenance: Fully automatic operation, no manual intervention; modular design, easy to disassemble and maintain; automatic flushing system regularly cleans the RO membrane, reducing maintenance workload.
Customizable Design: Modular design, customizable capacity (0.25 m³/h to 100 m³/h) according to user needs; tailored for residential, commercial (hotels, schools, hospitals), and industrial (electronic, pharmaceutical, food) scenarios.
Safe & Hygienic: All wetted parts are made of food-grade 304/316L stainless steel and food-grade plastic, complying with FDA, GMP standards; no secondary pollution, ensuring water quality safety.
