7. Frequently Asked Questions (FAQ)

 

Q1: What are the advantages of double-pass RO compared with single-pass RO?

 

A double-pass RO system performs a second desalination process after the first RO stage, providing higher water purity, better stability, and is suitable for industries requiring higher water quality standards.

 

Q2: Can this system treat well water or groundwater?

Yes, it can. For well water or groundwater applications, it is recommended to install a water softening system or chemical dosing system to protect the RO membranes and extend their service life.

 

Q3: Does the equipment require a dedicated operator?

No. The system can operate automatically and is equipped with automatic protection functions such as low water level protection, low pressure protection, and high pressure protection. Daily operation only requires regular inspection and filter replacement.

 

Q4: How often should the filters and RO membranes be replaced?

 

• Pretreatment cartridge filters: normally replaced every 3–6 months
• RO membranes: service life is typically 2–3 years, depending on raw water quality and maintenance conditions.

 

Q5: Can the system be customized for other capacities?

Yes. We provide customized solutions from 0.25–5 m³/h, with optional modules such as EDI, sterilization systems, variable frequency water supply systems, and other functional upgrades.

 

Q6: What are the power consumption and water recovery rates?

The power consumption of the 1 m³/h model is approximately 2.2 kW. The system recovery rate is 65–75%, providing an energy-efficient and water-saving solution.
