Frequently Asked Questions (FAQ)
Q1: What types of chemical wastewater can this ZLD system treat?
A: Our system is designed to handle a wide range of chemical effluents, including those from pharmaceutical, petrochemical, textile, electroplating, and food processing industries. It effectively removes heavy metals, organic compounds, salts, and other contaminants. For specific chemical compositions, we recommend a lab analysis to confirm suitability.
Q2: What is the typical lifespan of the 304 stainless steel components?
A: With proper maintenance, the 304 SS structure can last 15–20 years or more, even in corrosive chemical environments. The system’s corrosion resistance is further enhanced by passivation and optional protective coatings.
Q3: Is the system fully automatic? Can it be integrated with existing SCADA?
A: Yes, the standard control system is PLC-based with HMI and supports remote monitoring via Ethernet or RS485. It can be integrated with your existing SCADA or DCS system upon request.
Q4: What is the minimum order quantity (MOQ)?
A: As a manufacturer, we are flexible. The MOQ for standard models is 1 set, but we also offer pilot-scale units for testing before full-scale deployment.
Q5: Do you provide installation and commissioning services?
A: Yes, we offer on-site installation supervision and commissioning support for international clients. Our technical team can also train your operators. Additional service packages are available upon request.
Q6: How do you handle the solid waste (crystals) from the ZLD process?
A: The solid residue is typically a dry salt cake or mixed salts, which can be disposed of in licensed landfills or, in some cases, reused as raw material for other industries. We can provide guidance on solid waste management options.
Q7: What is the warranty period for this system?
A: We offer a standard 12-month warranty from the date of commissioning, covering manufacturing defects. Extended warranty options are available for purchase.
Q8: Can you customize the system for a specific flow rate or space constraint?
A: Absolutely. Our modular design allows for easy customization. We can adapt the system to fit your site layout, flow requirements, and treatment goals. Contact us with your parameters for a tailored solution.
