Frequently Asked Questions

  1. Q: What is the working principle of this system?
    A: It uses multi-media filtration, activated carbon adsorption, and precision filtration to remove suspended solids, organic matter, and chlorine from seawater, followed by evaporation concentration for brine treatment. The PLC automates backwash cycles.
  2. Q: Can this system handle high-salinity seawater?
    A: Yes, it is designed for Total Dissolved Solids (TDS) up to 45,000 ppm. For higher salinity, we can upgrade the material to duplex stainless steel.
  3. Q: What is the typical warranty period?
    A: Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. Extended warranty options are available upon request.
  4. Q: Does the system require special installation conditions?
    A: It requires a flat concrete foundation, 220V/380V power supply, and raw water inlet/outlet connections. We provide free layout drawing and installation manual.
  5. Q: What is the energy consumption per cubic meter of treated water?
    A: Typically 0.3-0.8 kWh/m³ depending on feed water quality and flow rate. Our system uses energy-efficient pumps and VFD to minimize costs.
  6. Q: Can I integrate this system with an existing RO plant?
    A: Absolutely. The system is designed as a drop-in pretreatment solution. We can customize the inlet/outlet flanges to match your existing piping.
  7. Q: Do you provide spare parts and after-sales service?
    A: Yes, we stock common spare parts and offer remote technical support. Our service team can visit your site for commissioning and training.
  8. Q: How long does delivery take?
    A: Standard delivery time is 30-45 days after order confirmation. For urgent projects, we can expedite within 20 days.
