Frequently Asked Questions
Have questions about ZLD technology? We have answers. If you don't see your question here, feel free to contact our experts.
Q1: What is Zero Liquid Discharge (ZLD)?
ZLD is an advanced water treatment process that completely eliminates liquid discharge from an industrial facility. It separates wastewater into two outputs: clean, reusable water (typically >98%) and solid waste (crystallized salts). This allows a plant to meet the strictest environmental regulations and maximize water recycling.
Q2: Is a ZLD system economically viable?
While the initial investment for ZLD is high, it becomes highly economically viable when you factor in:
- Soaring Costs: The rapidly increasing costs of fresh water and hazardous waste disposal.
- Energy Efficiency: Our use of MVR technology significantly reduces the operating cost compared to older thermal systems.
- Risk Mitigation: The immense cost of fines, shutdowns, and brand damage associated with non-compliance.
In many cases, a Hanpu ZLD system offers a rapid return on investment.
Q3: What is the core process of a Hanpu ZLD system?
Our typical ZLD solution follows a proven, multi-stage process:
- Pre-treatment: To remove solids and scale-forming ions, protecting downstream equipment.
- Membrane Concentration: Using Reverse Osmosis (RO) to recover the bulk of the water at low energy cost.
- Thermal Evaporation & Crystallization: Using our high-efficiency MVR evaporators and crystallizers to treat the final, highly concentrated brine and produce solid crystals.
