Frequently Asked Questions (FAQ)
1. What types of brine can this equipment handle?
It is suitable for seawater brine, industrial brine (e.g., from chemical or mining operations), and concentrated brine from reverse osmosis reject streams. The 304 stainless steel construction resists chloride corrosion, but for highly aggressive brines (e.g., high chloride or acidic), we recommend SS316L or duplex stainless steel.
2. What is the typical payback period for this equipment?
Payback varies based on brine volume, salt price, and energy costs. For a typical 10 m³/day system, clients often recover their investment within 12–18 months through reduced waste disposal fees and salt sales.
3. Do you provide installation and training?
Yes, we offer on-site installation supervision and operator training for your team. Remote technical support is also available via video call.
4. Can the PLC control system be integrated with existing plant SCADA?
Absolutely. Our PLC supports Modbus, Profibus, and Ethernet/IP protocols for seamless integration with most SCADA systems.
5. What is the minimum order quantity (MOQ)?
We accept orders starting from one unit. For custom specifications, please contact our sales team for lead time and pricing.
6. How long is the warranty period?
Standard warranty is 12 months from commissioning. Extended warranty plans are available upon request.
7. What spare parts should I keep in stock?
We recommend keeping a set of seals, gaskets, and a spare PLC module. A detailed spare parts list will be provided with the equipment manual.
8. Do you have a reference list for similar projects?
Yes, we can share case studies and references under a non-disclosure agreement. Please contact us to discuss your specific application.
