Frequently Asked Questions (FAQ)
Q1: What type of wastewater can this evaporator handle?
A: This evaporator is specifically designed for high-salinity wastewater containing sodium nitrate. It can also be adapted for other nitrate salts with minor modifications.
Q2: How does the triple-effect evaporation work?
A: The system uses three evaporator stages in series. Vapor from the first stage heats the second stage, and vapor from the second heats the third, significantly reducing steam consumption.
Q3: Is the PLC system difficult to operate?
A: No, the PLC comes with a user-friendly touchscreen interface. Operators can start, stop, and monitor the process with minimal training. Remote monitoring is also available.
Q4: What is the typical payback period?
A: Depending on the scale and local energy costs, many clients recover their investment within 1–2 years through reduced disposal fees and recovered salt sales.
Q5: Can the evaporator achieve zero liquid discharge (ZLD)?
A: Yes, when combined with a crystallizer or dryer, the system can achieve ZLD. We offer integrated solutions upon request.
Q6: What materials are used for corrosion resistance?
A: Standard construction uses SS304 or SS316L stainless steel. For highly corrosive environments, we can upgrade to duplex stainless steel or other alloys.
Q7: Do you provide installation and commissioning services?
A: Yes, we offer on-site installation guidance and commissioning support. Our team can also provide training for your operators.
Q8: What is the warranty period?
A: We offer a standard 12-month warranty against manufacturing defects. Extended warranties are available as an option.
