Product Introduction
The 250LPH Reverse Osmosis RO System is designed for electrophoretic coating lines that require efficient paint recovery and high-quality water reuse. By combining a specialized concentration membrane, reverse osmosis technology, and ion exchange purification, this system separates valuable electrophoretic paint components, removes dissolved impurities, and produces reusable process water.
This integrated solution helps manufacturers reduce wastewater discharge, improve material utilization, and lower long-term operating costs.

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.
