Dyeing Factory RO Water Treatment System

I. Dyeing Factory RO Water Treatment Equipment Overview

1. Definition:

 • Reverse osmosis (RO) system that treats and produces 10 tons of pure water per hour, applicable to medium and large-scale water use scenarios.

2. Working Principle:

 • High-pressure osmosis: water is pressed through a high-pressure pump (usually 4-8MPa) into a semi-permeable membrane (pore size 0.0001μm), which intercepts bacteria, viruses, heavy metals, organic matter and other impurities.

 • Separation efficiency: pure water permeability ≥95%, adjustable wastewater ratio (1:1-1:3, depending on water quality).

Ⅱ. Dyeing Factory RO Water Treatment System Composition and Function

1. pretreatment system

 • raw water pump: to provide stable inlet pressure.

 • Multi-media filter: remove suspended solids and sediment (precision 50-100μm).

 • Activated carbon filter: adsorb residual chlorine, organic matter (CTO cartridge life of about 6-12 months).

 • Softening filter: reduce hardness through ion exchange (prevent RO membrane scaling).

2. Reverse osmosis system

 • Core components: rolled RO membrane (such as Dow, Hydronic brand, life expectancy of 2-3 years).

 • Auxiliary components:

    • High-pressure pump (frequency conversion control, energy saving 10%-15%).

    • Online monitoring instrument (conductivity, pressure, flow rate real-time display).

    • Automatic flushing module (reduce membrane pollution).

3. Post-treatment system

 • pH adjustment: add lye to neutralize acidic water (for industrial ultrapure water needs).

 • Ultraviolet sterilization: further inactivate microorganisms (optional).

Ⅲ. Dyeing Factory RO Water Treatment System Core Advantages

1. Purification effect Removal rate ≥99.99% (bacteria, viruses, heavy metals)

2. Stability Fully automatic control, fault self-diagnosis and alarm

3. Maintenance Costs Filter cartridge annual replacement cost of about 5,000-10,000 yuan (depending on the quality of the water)

4. Energy saving Low-pressure membrane design, energy consumption is reduced by 20% compared with the conventional system

Ⅳ. Dyeing Factory RO Water Treatment System Application Scenarios

1.Industrial field

 • Electronics industry: semiconductor cleaning, circuit board manufacturing (resistivity ≥ 10MΩ-cm).

 • Pharmaceutical industry: water for injection, oral liquid preparation (in line with GMP standards).

2. Commercial Scenario

 • Direct drinking water system for hotels and schools (support daily water consumption for 500-1000 people).

3. Special needs

 • Boiler make-up water, laboratory ultrapure water pre-treatment.

V. Selection Guide

1. Water quality matching

 • High hardness areas need to be strengthened pre-treatment (such as the addition of scale inhibitor injection device).

 • Fluoride/arsenic water sources need to customize special membrane elements.

2. Brand and after-sales

Priority is given to manufacturers who have passed the ISO9001 certification

Ⅵ. Maintenance points

1. Daily inspection: pressure gauge fluctuation, conductivity abnormal alarm.

2. Regular maintenance:

   • Clean RO membrane (citric acid chemical cleaning) every 3 months.

   • Replace the precision filter (precision 5μm) every year.

 Conclusion: Reverse osmosis equipment is a cost-effective choice for industrial and commercial water, the purchase of a comprehensive consideration of water quality, budget and long-term maintenance costs. Our company can provide customized solutions to ensure efficient and stable operation of the system.
