Reverse osmosis equipment with high-pressure membrane separation technology to achieve efficient purification, modular design, efficient application in many fields, with strong purification, energy saving and other advantages.
Reverse Osmosis System Water Treatment Plant
I. Technical Principle: Pressure-driven Membrane Separation Revolution
Reverse osmosis (RO) equipment makes water molecules penetrate semi-permeable membranes with a pore size of <1 nm by means of high pressure (10-15 kilograms), intercepting dissolved salts (desalination rate of 98%-99.7%), heavy metals, bacteria (>99.99%) and viruses. For example, desalination can reduce salinity from 35,000 ppm to <500 ppm, and conductivity of produced water <10 μS/cm.
Ⅱ. the system composition: modular design to ensure efficient operation
1. Pre-treatment system
● Quartz sand filter: remove suspended solids, turbidity <5 NTU.
● Activated carbon filter: adsorption of residual chlorine, organic matter, anti-membrane oxidation.
● Precision filter (5μm): retain small particles, protect RO membrane.
● Softening device (optional): reduce hardness, prevent membrane scaling.
2.Reverse osmosis host system
● High-pressure pump: provide 10-15kg pressure.
● RO membrane module: polyamide composite membrane, life 1-3 years (standardized operation up to 3-5 years).
3. Post-treatment system (optional)
● EDI: Enhance water quality to resistivity ≥18 MΩ-cm (ultra-pure water).
● UV sterilizer: kill residual microorganisms.
III. Core Advantages: High Efficiency, Energy Saving & Wide Applicability
1. Deep Purification Capability
● Removes more than 99% of dissolved salts, heavy metals and microorganisms, and complies with WHO drinking water standards (TDS<500 ppm).
● Retain organic matter with molecular weight >100 Da and avoid chemical by-products.
2. Operational economics
● Energy consumption optimization: new membranes reduce desalination energy consumption to 2.5-4 kWh/m³.
● Recovery rate improvement: 80-90% recovery rate in industrial systems.
● Long-life components: RO membrane life of 3-5 years, pre-treatment cartridge replacement in 3-6 months.
3. System Flexibility
● Modular design: water production can be expanded up to 50 m³/h.
● Combined process compatibility: coupled with ultrafiltration and ion exchange to meet the needs of the electronics (resistivity ≥ 18 MΩ-cm) or pharmaceutical industries (bacterial endotoxin < 0.25 EU/mL).
4. Intelligent management
● Automatic flushing: Flush the membrane surface during shutdown to retard fouling.
● Failure warning: monitor the trans-membrane pressure difference, push the cartridge replacement reminder.
Ⅳ. Typical application scenarios
1. Industrial boiler make-up water: multi-media filtration + softening + secondary RO + EDI, water production ≥ 10 m³/h, conductivity ≤ 0.1 μS/cm.
2. Seawater desalination: pretreatment + high-pressure RO membranes + energy recovery, recovery rate of 40%-50% (such as the Saudi project 600,000 tons per day).
3. Electronic ultrapure water: RO + EDI + UV sterilization, resistivity ≥ 18.2 MΩ-cm, TDS < 5 ppm.
4. Food industry water: quartz sand + activated carbon + RO, to remove odors and microorganisms.
V. Selection and operation and maintenance
1. Selection principles: according to the water quality, use of the pre-treatment process and membrane element brands.
2. Operation and maintenance management: regular chemical cleaning (trans-membrane differential pressure rises 15%), pre-treatment cartridge replacement on schedule, monitoring membrane performance and timely replacement of aging components.
