Product Introduction
The 250LPH Reverse Osmosis RO System is an advanced water treatment solution tailored for the electrophoretic coating process. It integrates a specialized concentration membrane for electrophoretic paint, reverse osmosis technology, and ion exchange systems to recover paint efficiently, recycle wastewater, and minimize environmental impact. This system not only enhances resource utilization but also reduces operational costs for enterprises.
Features
1.Special Concentration Membrane for Electrophoretic Paint
- High-Efficiency Interception: The ultrafiltration membrane, with a pore size of 50 nm, effectively intercepts large molecular electrophoretic paint particles in cleaning water.
- Anti-Fouling Performance: Its smooth surface with a roughness of less than 5 nm ensures excellent anti-fouling properties and durability.
- Flow Channel Optimization: The diamond grid design improves water flow distribution, reduces pressure loss by 20%, and decreases cleaning frequency by 35%.
2. Reverse Osmosis and Ion Exchange Integration
- Efficient Desalination: The RO system reduces water conductivity to ≤50 μs/cm, meeting reuse standards.
- Fine Filtration: The cation and anion exchange system further lowers metal ion content, achieving a water quality of ≤0.2 μs/cm.
3.Operational Economy
- Energy Efficiency: The membrane's hydrophilic surface reduces energy consumption by 20%.
- Extended Service Life: Enhanced materials extend membrane life by 1.5 times, lowering replacement costs.
Operating Parameters
- Processing Capacity: 250 L/h
- Operating Pressure: 0.1–0.5 MPa
- Influent Conditions: Suspended solids ≤50 mg/L; Conductivity ≤50 μs/cm
- Water Quality: Conductivity ≤0.2 μs/cm; Suspended solids = 0 mg/L; Metal ions ≤0.1 mg/L
Working Principle and Process Flow
1.Preliminary Collection and Preprocessing
Wastewater from the cleaning tank is filtered through the special concentration membrane to separate fresh water from large molecular substances.
2. RO Reverse Osmosis Treatment
The 250LPH Electrophoretic Paint Cleaning Water Recycling Equipment further reduces water conductivity and suspended solids. Concentrated water is directed to sewage treatment for discharge compliance.
3. Ion Exchange Purification
RO-treated water enters the ion exchange system to remove residual metal ions and trace impurities, ensuring high-purity water for reuse.
4. Recycling Concentrated Liquid
Concentrated electrophoretic paint liquid is periodically sent back to the paint tank, reducing raw material waste and improving resource efficiency.
Usage and Maintenance
1.Operation Requirements
Ensure valves are properly positioned before initial operation.
Maintain pressure within 0.1–0.5 MPa to avoid automatic shutdown.
2. Maintenance and Cleaning
Use lactic acid solution every three months to clean membrane components.
Flush thoroughly with clean water post-cleaning to maintain stable performance.
3.Shutdown Precautions
Gradually turn off pumps and ensure membrane assemblies remain hydrated to prevent damage.
Application Areas
The Reverse Osmosis RO System is ideal for industries requiring efficient paint recovery and water reuse, such as automotive manufacturing and hardware electrophoretic coating lines. It excels in recycling electrophoretic paint cleaning water, cutting operational costs and supporting sustainable production practices.
