Frequently Asked Questions (FAQ)
Q1: What does ZLD stand for and how does it work?
A: ZLD stands for Zero Liquid Discharge. It is a water treatment process that eliminates liquid waste by recovering clean water and concentrating impurities into solid residues. Our system uses a combination of membrane filtration, thermal evaporation, and crystallization to achieve this.
Q2: What is included in the mill test report?
A: The mill test report verifies the chemical composition and mechanical properties of the materials used in the system, such as stainless steel grades. It ensures material quality and traceability, providing confidence in the system's durability.
Q3: Can the system handle high-salinity wastewater?
A: Yes, our ZLD system is designed to treat feed water with total dissolved solids (TDS) up to 50,000 mg/L. For extremely high salinity, additional pre-treatment or customized configurations are available.
Q4: What is the typical payback period for this system?
A: Payback depends on local water costs, discharge fees, and energy prices. Typically, clients recover their investment within 2–4 years due to reduced water purchase and waste disposal costs. Our team can provide a detailed ROI analysis based on your specific data.
Q5: Do you provide installation and commissioning support?
A: Yes, we offer on-site supervision and technical guidance during installation and commissioning. Remote assistance is also available via our service team. Full documentation, including P&IDs and operation manuals, is provided.
Q6: How long is the warranty and what does it cover?
A: The standard warranty is 2 years from the date of shipment. It covers defects in materials and workmanship under normal operating conditions. Consumables (e.g., membranes, filters) are excluded. Extended warranty options are available upon request.
Q7: What certifications does your company hold?
A: Our company is certified under ISO9001, ISO14001, OHSAS18001, and many other international standards including HACCP, TL900, QS9000, SA8000, ISO17799, ISO10441, ISO16949, TS16969, ISO19011:2000, and others. These certifications reflect our commitment to quality, environment, and occupational health.
Q8: Can you provide references or case studies from similar installations?
A: Absolutely. We have numerous successful projects in power, chemical, and pharmaceutical industries globally. Upon request, we can share non-confidential case studies and contact references.
