Frequently Asked Questions

Why does this 4m³/h RO system include both multi-media filter and softener?
The multi-media filter removes suspended solids, while the softener eliminates calcium and magnesium ions. This combination is essential to prevent membrane fouling and scaling, significantly extending the lifespan of the RO membranes.
What industries is this system suitable for?
Due to its high-purity output (≤20μS/cm) and SS304 construction, it is ideal for the food and beverage industry, pharmaceutical production, and electronics manufacturing.
Can the equipment be customized for specific requirements?
Yes, we offer full OEM/ODM customization services. We can adjust capacity, materials, and control systems based on your specific raw water quality and output needs.
What is the desalination rate of this system?
The system features a desalination rate of ≥98% using high-quality 8040 Polyamide membranes, ensuring highly purified water output.
What type of control system is used?
The system utilizes an advanced PLC control system (S7-200 compatible) with an RS485 interface for reliable, automated operation and easy monitoring.
