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.
